Transcript of Biology Photo Scavenger Hunt Project
Order: Apiales Lemon
Order: Sapindales Organisms in the Same Order but Different Families Oak Tree Maple Tree Birch Tree Order: Fagale
Family: Fagaceae Order: Fagale
Family: Aceraceae Order: Fagale
Family: Betulaceae Organisms in the Same Genus but are Different Species Genus: Cruciferous
Species: Cauliflower Genus: Cruciferous
Species: Broccoli Grass produces its own energy by way of photosynthesis and is therefore an autotroph. Autotrophs are on the first level of of the food chain. This grasshopper eats autotrophs as in this grass and is thus a heterotroph. Heterotrophs are 1st level consumers, meaning they are on the second level of the food chain. Organisms on Different Levels of the Same Food Chain Animal Adaptations If you look closely at Brook's paw you will see that it is webbed. Brook is a labrador retriever. Labrador retriver's were genetically engineered to work alongside duck hunters. When a duck would be shot by a lab's master the lab would go and retrieve it. Ducks' habitats are typically those of freshwater areas and in turn would be the prime hunting areas. This requires that labs be excellent swimmers. Their artifically selected webbed feet help in this task. Plant Adaptation This is leaf is that of a hosta. Hosta leaves are large and fan out parallel to the ground. This provides hostas with additional surface area in absorbing sunlight. Anther Filament Anther- the pollen-bearing part of stamen.
Filament- the stalk of stamen. Anther and Filament of Stamen Calvin Cycle Within the cells of this leaf are mitochondria. During nighttime hours the calvin cycle is run within the mitochondria. The Calvin cycle utilizes the products of ATP and NADPH from the photosynthesis reaction and carbon dioxide from the atmosphere and cycles it to produce NADP, ADP, and sugar. Cuticle Cuticle- a continuous layer of waxy substances on the outer layer of the epidermis of plants that protects against water loss. (Diagram- shiny surface of the orchid.) Decomposer Worms generally decompose any dead substances within or on the surface of soil, ranging from dead leaves to one's garbage. Flower Ovary The ovary of a flower is the enlarged lower part of the pistil in angiospermous plants, enclosing the ovules or young seeds. The highlighted portion of this image is of an ovary of a flowering plant. Lichen Lichen is formed by the symbiotic relationship of algae and fungus. Lichen occurs most commonly as a greenish hue along with the possible yellow, brown, gray, or blackish growth on crusty surfaces as in tree bark. Seed Dispersal By Way of Wind Dandelion seeds, as those pictured here, are dispersed by way of the wind. The seeds are attached to light feather like structures that act as a parachute. This light parachute design allows for the seeds to take loft with and be carried by the wind to new locations. Genetic Variation Within a Population Genetic variation describes the naturally occurring differences among individuals of the same species. Genetic variation promotes flexibility and survival in the event of the environment changing. Genetic variation in this portion of my back yard is plant height. In this area of my yard there is a short time window for sunlight. In such a near constantly shaded area the taller plants have the advantageous genetic variation as they are exposed to more sunlight than the shorter plants. C4 Plant C4 plants, as in corn, can undergo photosynthesis at lower concentrations of CO2 than C3 plants. With that, the CO2 will keep decreasing after the lower limit of C3 plants, until it reaches the later level of the C4 limit. In addition, C4 plants often have thylakoids with reduced complexes that produce oxygen (photosystem II) along with bundle sheath cells deep in the leaf so atmospheric oxyhen cannot diffuse easily into them. These combined adaptations maximinze C4 plants' carbon take-in and minimize the amount of oxygen produced as a useless bi-product of photosynthesis. Ethylene Ethylene, a small hydrocarbon gas, is naturally occurring and acts as a ripening hormone. Some fruits produce ethylene as ripening begins. Ethylene is responsible for the changes in texture, softening, color, and other processes involved in ripening. Furthermore, ethylene continues as an aging hormone in plants, and can cause plants to die. Ethylene is behind the shift in color from unripened green bananas to the yellow ripe bananas. Parasitism Parasitism is a relationship between organisms in which one organism, the parasite, lives off the other organism, the host, and harms it. This Japanese beetle eats the leaves and petals of this plant. Fermentation Fermentation is the use of yeast to convert carbohydrates into alcohol or the use of bacteria to create lactic acids in certain foods. Fermentation is frequently used in the creation of alcoholic beverages and the aging of cheese. Gymnosperm Leaf A gymnosperm is a vascular plant not having seeds enclosed in its ovary but rather enclosed in cone like structures. Hermaphrodite An organism, as in an earthworm or plant, that contains normally both the female and male reproductive organs. Lipid Used for Energy Storage Lipids comprise fats, oils, and waxes used for energy storage. Butter is an example lipid. When one's doctor says they have an excess of fat, it means they have an excess of lipids that their body does not need. Abnormal lipid levels are common in diabetes. Modified Root System Some plants have a root system that contains bulbs, as in garlic plants. The garlic one uses in cooking is the bulb. Bulbs contain food reserves to enable the plant to survive adverse conditions. Mutualism Mutualism is a symbiotic relationship in which both organisms benefit. In the case of the bee and flower, the bee pollinates the flower and gains nectar in return. Sporophyte Sporophyte phase- a diploid plant body grows and eventually produces spores through meiosis. These spores divide by way of mitosis to produce haploid, gamete producing bodies. The union of two gametes during fertilization produces a diploid zygote, which divides through mitosis to form a new sporophyte. A fern is a sporophyte. Stigma Style Stigma and Style Stigma- the apical end of the style where deposited pollen enters the pistil.
Style- the middle portion of the female productive part (carpel) of a flower, connecting the ovary to the stigma. Unicellular Organism Unicellular organisms are prokaryotic as they only consist of one cell. Example unicellular organisms are bacteria, such as the "live cultures" found in yogurt. An Organism with an Exoskeleton Ever step on an insect and heard a crunching sound? That would be the insect's exoskeleton. An exoskeleton is the protective or supporting structure covering the outside of the body of many animals, such as the thick cuticle of arthropods. This cricket is an arthropod and contains the characteristic exoskeleton. Long Day Plant A long day plant is a plant that flowers only after being exposed to light periods longer than average plants' typical length, such as towards the end rather than early summer. Lettuce, spinach, and some types of wheat are long-day plants. Genetically Modified Food Genetically modified foods are crop plants created for human or animal consumption using today's latest biology techniques. These organisms have been artificially selected so that the desired traits as in color, nutritional value, and aging have been increased. Tomatoes are one of the many foods treated for these qualities.
