A bud is growth point of a stem. Terminal bud is the growth point at the end of the stem that adds to the stem's lengths. Axillary bud is the growth point that occurs above each leaf. Buds may also be classified as either vegetative or reproductive. If the bud grows into a region of a stem that mainly produces photosynthetic leaves it is a vegetative bud, but if the bud grows into a stem that produces a flower it is a reproductive bud.
Compound leaf is a leaf in which the blade is dissected into leaflets.
Two types of compound leaves include Pinnately compound and palmately compound. If the blade is dissected into leaflets and they are arranged around the pinnate arrangement of veins - it is a pinnately compound leaf. If the blade is dissected into leaflets and they are arranged around the palmately arrangement of veins - it is palmately compound leaf. A Twig is the portion of a stem that has grown in the most recent growing season. Some plants lose their leaves during unfavorable growing seasons - these plants are referred to as deciduous plants.
