HORTICULTURE

Detailed explanation-1: -A bud formed in the axil of a previously formed leaf is called an axillary bud, and it, like the leaves, is produced from the tissues of the stem. During the development of such buds, vascular bundles are formed within them that are continuous with those of the stem.

Detailed explanation-2: -Structurally, twigs are made of stacks of shoots with alternating nodes and internodes. Internodes elongate creating the effect called growth. Nodes are non-elongating areas which generate flowers, leaves, buds, and other twig parts. A node can be considered just the localized area where a twig component is generated.

Detailed explanation-3: -Leaf scars are crescent shaped and have small, circular bundle scars within them where vascular bundles traversed the plant tissues. A leaf scar will be located below a bud, branch, or bud scar. Plants that grow in temperate regions generally have a growing season.

Detailed explanation-4: -The leaf is attached to the plant stem by the petiole.
