HORTICULTURE

Detailed explanation-1: -The growing portion at the apex of the shoot is the terminal bud of the plant, and by the continued development of this bud and its adjacent tissues, the stem increases in height. Lateral buds and leaves grow out of the stem at intervals called nodes; the intervals on the stem between the nodes are called internodes.

Detailed explanation-2: -Root is a part of a plant which is present below the ground. Except for roots, all the parts of a plant like flowers, leaves and fruits grow on stems.

Detailed explanation-3: -In a plant, the point on the stem where leaves develop is called a node. The region between two adjacent nodes is called the internode. Mostly one leaf emerges per node.

Detailed explanation-4: -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 (cambium). Intercalary meristem is present at the base of the leaves or internodes (between two nodes) on twigs.
