Cellulose is defined as a fibrous carbohydrate found in the cell walls of plants.
This picture of paper represent cellulose because paper is made from the 30% of cellulose found in a tree.
Chitin is defined as a polymer of nitrogen-containing polysaccharide, made from carbohydrates, rendering a tough covering on some organisms.
This picture of a scorpion shows an arthopod with an exoskeleton that is chitinous.
Disaccharide is defined as a sugar, or a carbohydrate, composed of two monosaccharides, yielding two monosaccharide monlecules on complete hydrolysis. One example being lactose.
Milk naturally contains lactose, which is a complex sugar, or carbohydrate.
Monosaccharide is defined as a the simplist form of carbohydrate, and cannot be broken down to simpler sugars. Examples of monosaccharides are glucose, fructose, and ribose.
This picture of tree sap is an example of glucose.Glucose is one of the primary molecules which serve as energy sources for plants and animals.
A polysaccharide is defined as a complex carbohydrate composed of a chain of monosaccharides joined together by glocosidic bonds.
This picture of corn starch is an example of a starch, which is a polysaccharide. The formation of starches are the way that plants store glucose.
An amniotic egg is defined as a shelled egg where an embryo develops within a fluid-filled amniotic sac and is nourished by a yolk. The egg is an example of a storage protein and contains ovalbumin, and serves as an amino acid source for developing embryos.
Endosperm is defined as the tissue surrounding the embryo of flowering plant seeds, that provides nutrition to the developing embryo. An example of a product of endosperm is flour, which is used to make bread. The endosperm contains starchy carbohydrates, proteins and small amounts of vitamins and minerals.
An enzyme is defined as a chemical substance that is produced in a plant or animal, and the protein aids in the speed of chemical reactions.
The human digestive tract consist of enzymes, and contains amylase. Amylase helps breakdown complex carbohydrates into smaller chains.
Homeostasis is defined as the ability of an organism or cell to seek and maintain a condition of equilibrium. This picture shows how the organism will shutdown parts of itself to survive. The stored protein reserves in vegetative cells provide the building blocks for rapid expansion of vegetative structures after periods of dormancy.
Territorial behavior is defined as the methods of which an animal, or group of animals, protects its territory.
In this picture, my dog Slinkey, is showing his teeth in an act of defense to warn, in this case, the camera to back off. The brain recieves messages, or hormonal proteins, which help to coordinate certain bodily activities.
A heterotroph is an organism that is unable to make its own organic compounds from inorganic sources, like photosynthesis, hence why it feeds on organic matter, or other organisms. Also called a consumer. This is a spiny backed orb weaver spider and uses it's web to catch and eat prey.
The spiny backed orb weaver spider is part of the arthropoda phylum, and animalia kingdom.
An ectotherm is an animal that cannot regulate it's own body temperature. This gecko is a cold blooded animal and classified as an ectotherm, because it needs to seek an outside source of heat to survive. The gecko is a part of the chordata phyla, in the animalia kingdom.
The exhibit to the left is Oscar the Cat. He identifies the term epithelial tissue, which is a type of animal tissue made up of densely packed cells to act as a covering or lining of various bodily surfaces, or more simple, epidermis.
The picture of his stomach is to also focus on what used to be in his digestive tract. He was just recently wormed because he had hookworms, part of the nematoda phyla, and animalia kingdom.
A littoral zone organism is an organism inhabiting the seashore. This used to be clam, was found at Port Aransas on the coastline, and is part of the mollusca phyla, in the animalia kingdom.
Littoral Zone Organism
Radial symmetry in an animal is a characteristic described as pie rememblance when cutting different planes into roughly identical pieces. This starfish shows radial symmetry in it's five legs. Though one is missing, they are all roughly the same. The sea star is a part of the echinodermata phyla, in the animalia kingdom.
Genetic variation is when the genes of organisms within a population change. Here are two dogs, Rosy, left, and Moose, right. The coloration and different features about the two dogs have changed over many years. Since all dogs started from the wolf, and there are many different breeds today, the genetics have varied.
Genetic Variation within a Population
Cartilage is defined as a more flexible and compressible substance than bone and often serves as an early skeletal framework. In this case, the ears of my rabbit Cali, serve as the example.
Described as a warm-blooded animal who maintains a constant body temperature, my rabbit Duchess doesn't require an outside heat source to maintain a state of homeostasis. She is a mammal who makes her own body heat.
to the Leporidae
family in the
mammalia class.These two
the difference in
In botany, the flower ovary is an enlarged basal portion of the pistil, and develops seeds upon fertilization. Like this peach seed, it was once matured into a fruit by the flower ovary, and was kept inside the skin of the actual peach.
Ethylene is a plant growth substance involved in promoting growth, epinasty, fruit ripening, senescence and breaking of dormancy. It is a plant hormone that helps to ripen fruit, like this nectarine.
The peach seed and the nectarine are almost classified the exact same way. The nectarine has an orange inside and smooth skin, while the peach has a white inside with a fuzzy skin. Through reserching these two fruits, it is thought that they were named differently for marketing reasons. The two fruit are still two different species.
Angiosperm is a flowering, fruit-bearing plant or tree which has seeds in a closed ovary. This bell pepper found in my garden, or also commonly know as a capsicum, has seeds on the inside that classifies the plant as an angiosperm.
The capsicum is in the solanales order, but in the solanadeae family.
Though many might say a potato is a root, it is actually a stem, called a "tuber". They are swollen regions in the stem that store food for subsequent growth.
The potato is a part of the solanales order, but in the solanaceae family.
Modified Stem of a Plant
An autotroph is another word for a producer. An autotroph is an organism capable of making nutritive organic molecules from inorganic sources, via photosynthesis. This twisted acacia plant makes it's own food through photosynthesis.
The twisted acacia is a part of the fabales order, but in the fabaceae family.
Tropism is the turning or bending of a part of an organism toward or away from an external source like light, heat, or gravity. In this picture, it shows a velvet mesquite growing nearly completely sideways. This is because of it's attraction toward the light.
The velvet mesquite is a part of the fabales order, but in the faboideae family.
A modified leaf of a plant is a leaf of a plant that has other functions to the plant other than photosynthesis. This greenbriar has leaves that are used to grasp onto the fence for support in the weak stem.
Greenbriar is a monocot, classified that way because of the parallel veins on the leaves of the plant.
Modified Leaf of a Plant
Seed dispersal is a plant's way to distribute it's seeds away from the parent plant. This beggar's lice is using the animal dispersal technique by using the sticky burrs to attach the seeds to passing organisms.
Beggar's lice is a dicot because the plant's root grow from the radicle, or the first part of the seedling emerging from the seed, downward.
The carrot is a modified root of a plant. It serves as an enlarged taproot, where these roots function in the storage of food as carbohydrates. When the plant flowers, the carrot uses these stored carbohydrates.
The carrot is a part of the plantae kingdom, in the angiosperm division.
Modified Root of a Plant
Cambium is a meristematic plant tissue, that is commonly present as a thin layer of new cells on both sides. This picture shows the rings of this elm tree, formed over the years as new cells formed each year.
The elm tree is a part of the plantae kingdom, in the magnoliaphyta division.
A habitat is a plavce where an organism or a biological population normally lives or occurs. This picture shows a small habitat where organisms live alongside many others.
In the center of this picture is a cedar tree, a part of the plantae kingdom, in the pinophyta division.
The phloem of a vascular plant is a tissue that functions primarily in transporting organic food materials from the leaves to all parts of the plant, not just up and down like the xylem. This picture of an oak sapling shows the inner tissue of the tree, where the phloem is.
Parasitism is defined as a type of symbiosis where one organism benefits at the expense of another organism. This mistletoe is a parasitic plant. It is grown into the tree, and using it for food and leverage.
Mistletoe is a dicot because the root starts from the radicle, but then taps into the host's nutrients.
Bilateral symmetry is a term given to an organism which is divisable into equal mirror halves in one plane only. This butterfly is symmetrical if the plane is vertical putting a wing on each half.
The butterfly is in the insecta class, but in the lepidoptera order.
Cellular respiration is defined as a series of metabolic processes within a cell where energy is harvested from organic materials and stored for later use that requires energy for the cell. The cell takes in molecular oxygen and releases carbon dioxide. This small hackberry tree is shown to represent the intake of carbon dioxide, and the release of oxygen.
The hackberry tree is a dicot because the arrangement of vascular bundles are in concentric circles.
Detritivores are described as organisms that feed on detritus or organic waste. These termites were found in the base of a fallen dead tree. When the termites eat dead trees, they help the environment by making space for new organisms.
Termites are in the insecta class, but in the isoptera order.
The cuticle layer of a plant is a continuous layer of waxy substance on the plants epidermis, or leaves in this case. The waxy layer contains cutin and protects against water loss and damage.
The boxwood bush is a dicot because the vascular bundles are in concentric circles.
Cuticle Layer of the Plant
Analogous structures are structures of different species having similar functions, but not from the same evolutionary origin. This picture shows a red wasp and a picture of a cardinal, both having wings, but not from the same evolutionary origin.
The red wasp is in the insecta class, but in the hymenoptera order.
R-strategist organisms are ones that have many, small, offspring that die easily, and don't live long. This fly has many offspring, dies easily, and are adults for only days.
This fly is in the insecta class, but a part of the diptera order.
This animal, or arthropod, has a segmented body. This insect has a head, thorax, and an abdomen. It also possesses an exoskelton, and jointed appendages.
This boxelder bug is a part of the insecta class, but in the hemiptera order.
Animal that has a Segmented Body
Vestigial structures refers to the part which is greatly reduced from the original ancestral form and is no longer functional, or reduced to an altered form. This used to be snake, has a pelvis, which is no longer needed because of the lack of appendages.
The snake is a part of the animalia kingdom.
Fungi is a general term used to denote a group of eukaryotic protists, including mushrooms and molds. Characterized by the absence of chlorophyll, fungi does not use photosynthesis to make food. This picture shows some kind of fungus on a decaying piece of wood.
Fungi is one of the six kingdoms.
The xylem is a type of vascular tissue and is primarily involved in transporting water and nutrients, and providing structural support. This unfortunate piece of pecan firewood represents the xylem with the account of wood vessels and xylem fibers transporting nutrients through the plant.
The pecan tree is a part of the plantae kingdom.
Hydrophilic is the characteristic of having an affinity for water, and capable of interacting with water through hydrogen bonding. Like this sea salt, the molecules have polar groups, enabling them to dissolve in water.
In the sea salt is a bacteria called halobacterium ("salt" or "ocean bacterium"). Halobacteria are halophilic, which means they can grow in extremely high salinity environments. Halobacterium are in the archaebacteria kingdom.
Fermentation is an anaerobic, doesn't require oxygen, cellular process in which organic foods, or water, are converted to simpler compounds. Vinegar is made by mixed fermentation of yeast followed by acetic acid bacteria. This is the same process in which yogurt is made, just not the same bacteria.
The bacteria used in fermenting vinegar is called acetobacter aceti, and belongs to the eubacteria kingdom.
Altruistic behavior is defined as an organism costing it's own life, for the benefit of others. These red fire ants are behaving altruistically in that none of these worker or soldier ants will ever reproduce, but they devote their entire life to making a nest, finding food, and aiding the queen.
The different allele present in these ants is their job, either worker or soldier.
The crapes/crepes myrtle was introduced to America in the 1700's from Japan, and is now in many varieties all over the United States.
The different allele present is the flower colors. Depending on where they grow and what species determines the flower color.
This catclaw acacia has adapted by growing thorns, and having a cuticle layer on the leaves so that it can survive in arid climates.
The different alleles present are the size of the thorny spikes on the stem and branches of the plant.
Adaptation of a Plant
Hydrophobic is the characteristic of lacking an affinity for water, or quite literally, "the fear of water". Some examples include oils, fats, and greasy substances. Olive oil is insoluable in water and eventually separates when put together, and therefore hydrophobic.
The different allele is the olive. The olive can be either green or black.
A large group of symbiotic associations between fungi and green algae. The associations are so stable and of such varied but distinct types that some have their own species. This picture shows some lichen growing on the bark of a tree.
The algae part of the lichen is a part of the bryophyte division of plant.
Water adhesion is a characteristic that water has where it will stick to other objects besides other water molecules. In this case, the penny has water sitting on top of it, and the edges of the water are actually hanging over the edge of the penny. Without this property of water, the water would not sit on top of the penny.
A eukaryote can be a single-celled or multicellular organism whose cell contains a distinct membrane-bound nucleus. A eukaryote can be in the animalia, plantae, fungi, and protists kingdoms, because their cells are structured with organelles, but the nucleus in particular.
This picture of yeast is a eukaryote because yeast is in the fungi kingdom, with eukaryotic cells.
