AP BIOLOGY

Detailed explanation-1: -In botany, a bud is an embryonic or underdeveloped leafy offshoot that forms either plants’ vegetative (leaves) or reproductive (flowers) structures. There are several types of buds, but the terminal bud, also referred to as the apical or apex bud, is most commonly associated with growth.

Detailed explanation-2: -Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root. The girth (width) of the stem or root increases due to lateral meristem. Intercalary meristem is present at the base of the leaves and internodes (between two nodes) on twigs.

Detailed explanation-3: -A terminal bud grows at the tip of a shoot and causes the shoot to grow longer. These buds produce hormones that move downward along the shoot, inhibiting the growth of other buds on that shoot. Lateral buds grow along the sides of a shoot and give rise to the sideways growth that makes a plant bushy.

Detailed explanation-4: -When a seedling begins growth, it produces a growing tip, also known as a terminal (apical) bud. Like the growing tip of a root, this area contains the actively dividing cells of the apical meristem–responsible, in stems, for stem elongation and leaf development.
