Ap Biology

Carbohydrate-fibrous- they mostly come from green vegetables, made up of cellulose and they help move starch through your system and, in the process, allowing your body to extract their nutritional elements. This cucumber represents fibrous carbohydrate.

Autotroph- An autotroph is an organism that makes its own food, often through the process of photosynthesis, this tress represent autotroph because it makes its own food through photosynthesis and it’s able to grow without eating other organism.
Heartwood- center of a stem that is made up of dead cells which give trees the support needed for standing. This picture showed a cut tree, and the center of it.


Gastropod- characteristically having a single usually having a shell or no shell at all, a ventral muscular foot for locomotion, and eyes and feelers located on a distinct head. An example would be a snail, in this picture there is a snail, the snail has eyes and fellers located on a distinct head.
Flower ovary- the ovary is at the bottom and middle of all stamens. Flower ovaries hold, protect, and nourish the ovules of the plant before the fertilization. This picture shows the location of the flower ovary.
Cuticle layer of plant - The cuticle is the waxy coating on the uppermost surface of this leaf, the picture of the leaf is composed of layers and its shiny, the cuticle help the plant from water lost.


Enzyme- a chemical produced by cells to speed up specific chemical reaction. This picture shows an apple turning brown, which is releasing the enzyme.
Scale with animal with two chambered heart-an animal that has scale and two chambered heart. This picture show a fish, a fish has scale and a two chambered heart.
Epithelial tissue- covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This picture shows skin, skin cover the surface of the body and is made up of cells
Cambium- In a tree the cambium is located between the inner bark and the sapwood. This picture shows part of the tree to show where the cambium is located inside the outer bark.
Deciduous Leaf- they tend to fall off from trees or lose their leaves seasonally. This picture shows a leaf that fell from the tree, this kind of leaf usually falls off seasonally.
Conifer leaf- has needle shaped leaves and come from a tree that produces its seeds. In this picture shows a tree that is made up of conifer leaves.
Bryophytes- are plants that lack vascular tissue and other parts, this picture shows moss. Moss is considered a bryophyte because it doesn’t produce seeds or flowers.
Pollinator- Pollinators are what move pollen from the anthers of a flower onto the stigmas. This picture shows a bee, bees are the most common known pollinators, they pollinate by getting some pollen on their legs and rubbing it off in a different flower.
Pollen- The pollen is the structure that will produce the sperm in the seed plants. It is the yellow dust located at the tip of the stamen. This picture shows the little yellow dust that is at the tip of the stamen on the flower.
Long Day Plant- These types of plants need at least more than 6 hours of sunlight to produce. That is why most long-day plants flower during the late spring and early summer when the days are the longest. This picture shows a lettuce plant, lettuce needs a lot of sunlight to become green and fresh and grow strong.
Thorn of a plant- plants that have thorns on their stem like a rose, this picture shows a thorny stem of a rose.
Radical symmetry- organism in which a vertical cut through the axis in any of two or more produces two of the same image. In this picture there is a lemon cut in half, it had radical symmetry. Once cut it looked like the other half and if cut again.
Connective tissue- a type of tissue made up of fibers forming a framework and support structure for body tissues and organs. In this picture is an ear, an ear has connective tissue.

Stem-Woody- this mean that the stem of a plant is woody and usually they store a moderate amount of starch in the living cells. An example of a woody stem would be a tree, like in this picture.
