18.) Endotherm
Definition: An endotherm is an animal that can regulate it's own body temperature and keep it constant, or a warm-blooded animal.
* A cat is an endotherm because they are warm blooded animals.
19.) Adaption of an animal
Definition: An adaptation is a trait that becomes commonplace in a species because it benefits the survival of organisms in that species in someway.
* A dog is an adaption of an animal because they have fur to keep them warm.
20.) Ethylene
Definition: A gaseous plant hormone directly associated with the ripening of fruit.
* A banana is an example of a ethylene because they grow and change from green and hard to rip and ready to eat.

21.) Lichen
Definition: Symbiotic organism, associated with fungus or algae.
* This is an example of lichen because it's like fungus or tree moss.
22.) Vestigial Structure
Definition: A vestigial structure is an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species.
* The ear is an example of a vestigial stricture because there is an entire group of muscles attached to our ears that just sit there and move nothing.
23.) Stem- woody
Definition: a stem that is hard textured and has secondary xylem.
* A tree is an example of a woody stem because it's hard textured.

24.) Stem- Herbaceous
Definition: The stem of a plant that dies down to its roots every year during cold climates.
* This flower is an example of a herbaceous stem because it dies in the winter.

25.) Glycogen

Definition: a substance deposited in bodily tissues as a store of carbohydrates.
* Chicken is an example of glycogen because is has one of the highest amounts of glycogen in it.
26.) Gibberellins
Definition: Gibberellins are defined as a class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of the seed and breaking of bud dormancy, and stimulate fruit development with auxin.
* A seedless watermelon is an example of a gibberellins because it takes away the seeds.
27.) R-strategist
Definition: R-strategists predominate as the ability to reproduce quickly in unstable environments. Many offspring are produced but each offspring has a poor chance of survival.
* Flies are an example or r-strategists because they live a short life and have many offspring.
28.) Gymnosperm Leaf
Definition: Gymnosperms are plants in which the seeds are produced in open organs.
* Pine trees are an example of a gymnosperm leaf because they have cones to help them reproduce.

29.) Radial Symmetry
Definition: A basic body plan in which the organism can be divided into similar halves by passing a plane at any angle along a central axis
* A tiger lily can be used as radial symmetry because if you cut it anywhere, it would be the same on both sides.
30.) Genetically modified organism
Definition: An organism whose genetic material has been modified, especially by genetic engineering.
* Rice plants can be modified in DNA to generate nutrients or increase grain size.
31.) Modified Leaf
Definition: When leaves do more then just photosynthesis and transpiration.
* Scales of an onion bulb are actually modified leaves that provide protection.
32.) Niche
Definition: A Niche is a habitat where an organism has everything it needs to survive.
* A nest is an example of a niche because birds eat and live in there.

33.) Amylase
Definition: An enzyme, found chiefly in saliva and pancreatic fluid, that converts starch and glycogen into simple sugars.
* Saliva is an example of amylase because it breaks down carbs and starches into simple sugar.
34.) Autotroph
Definition: An organism that is capable of making its own food.
35.) Parasitism
Definition: The relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it.
36.) Exoskeleton
Definition: A rigid external covering for the body in some invertebrate animals, esp. arthropods, providing both support and protection.
37.) Rhizome
Definition: A horizontal, usually underground stem that often sends out roots and shoots from its nodes.
38.) Fermentation
Definition: The chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.
39.) C3 Plant
Definition: A plant that turns CO₂ into CO₃ before going into the Calvin cycle of photosynthesis.
* Dandelions are an example of a C3 plant because they are a broad leaf plant and dandelions use this technique.
40.) Pine cone- female
Definition: Female cones tend to be rigid and more long lasting and don't provide pollen.
41.) Bilateral Symmetry
41.) K- strategist
Definition: Few offspring, nurtures each offspring thoroughly, long life span.
* Humans are an example of a K-strategist because we live long and take care of our children.

42.) Bilateral Symmetry
Definition: The property of being divisible into symmetrical halves on either side of a unique plane.
43.) Cuticle layer of a plant
Definition: A continuous layer of waxy substances covering over the outer surfaces of the epidermis of plants.
44.) Asexual Reproduction
Definition: A form of reproduction on which there is no exchange of genetic material.
45.) Angiosperm
Definition: A flowering, fruit-bearing plant or tree, the ovules of these plants develop within an enclosed ovary.
* Oranges are an example of a angiosperm because the seeds develop in an enclosed ovary.
46.) Phototropism
Definition: The growth response of plant parts to the stimulus of light, producing a bending towards the light source.
* A sunflower is an example of a phototropism because they grow toward the sun.

47.) Deciduous Leaf
Definition: Refers to a plant (usually a tree or shrub) that sheds its leaves at the end of the growing season

* A maple tree has an example of a deciduous leaf because they change colors and fall in autumn.
48.) Animal that produces uric acid as a waste product.
* A maple leaf is an example of bilateral symmetry because if you folded it in half it would be the same thing.
* This plant I found in my front yard is an example of a cuticle layer because it feels waxy and is shiny

49.) Genetic Variation within a population
Definition: Genetic differences both within and among populations.
*Hair is an example of genetic variation within a population because no two humans are genetically the same.
* This pine cone is a female because its rigid and there's no pollen.
* This is an example of an exoskeleton because it's an outside covering of a body.
* Strawberries are an example of an asexual reproduction because once the strawberry plant hits the ground, it develops new roots and grows a new plant.
* Dough is an example of fermentation because it expands.
* Potatoes are an example of a rhizome because its main growth is happening underground.
* Grass is an example of an autotroph because it gets energy from the sunlight.
50.) Modified root of a plant
Definition: Modified roots are roots which change their structures to carry out vital functions such as photosynthesis, gather oxygen, store food or water, or support the stem.
* A carrot is an example of a modified root of a plant because its roots adapt to its environment.
