How it works
|Types of plant parts Meristems Meristems, or buds, are actively dividing regions of cells that produce new plant parts. Any meristem can be in one of two states: vegetative or reproductive. Meristems in the vegetative state produce stems and leaves, and meristems in the reproductive state produce inflorescences. An apical meristem is found at the end (apex) of a plant stem. An axillary meristem is found in the angle between leaf and stem (axil) on the side of a stem. If an axillary meristem develops vegetatively, a new branch will result. Internodes and leaves An internode is a portion of stem between (inter) two leaf nodes. Each internode is associated with one or two leaves. Reproductive parts Inflorescences are structures that hold flowers and fruits. Any time you see several flowers in the same spot on a plant, they are usually in an inflorescence. We stretch the meaning a little to include situations where flowers are single. Each inflorescence creates a number of flowers, and the flowers develop into fruits.|
