Plants have fruits to protect the seeds inside. A seed is the beginning of a plant.
Leaves make food by going through photosynthesis, it holds up the plant and carries chlorophyll.
The stem attaches almost all the parts to itself and helps keep the plant upright. It also acts like a highway in that it brings nutrients to other parts of the plant. A bud is a flower that hasn't bloomed yet. A branch is attached to the leaf and the stem. Leaves have vines and chlorophyll in them.
