BOTANY

Detailed explanation-1: -Lateral buds and leaves grow out of the stem at intervals called nodes; the intervals on the stem between the nodes are called internodes. The number of leaves that appear at a node depends on the species of plant; one leaf per node is common, but two or more leaves may grow at the nodes of some species.

Detailed explanation-2: -a leaf scar is the scar remaining after the leaf falls off. Bundle scars are the broken ends of the vascular bundles passing from the stem into the leaves. They are identified as small dots, discolorations, or raised bumps on the surface of the leaf scar ( not very visible here).

Detailed explanation-3: -This area is called a bundle scar, and it is the torn vascular bundle. Buds often form just above leaf scars, and they leave scars of their own. They are called bud scars.

Detailed explanation-4: -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-5: -For dicots, is commonly know when any plant shed their leaves naturally. Leaf scar is commonly phenomena to protect the living part from any infection. Leaf scars are also prominent in thicker grasses such as bamboos. Since there are leaf sheaths, the scars are circular, for example is a Bambusa rhizome.
