Detailed explanation-1: -Compound leaf: in a compound leaf, the leaf blade is clearly divided into many distinct parts called leaflets.

Detailed explanation-2: -In compound leaves, a blade has two or more subunits called leaflets: in palmately compound leaves, the leaflets radiate from a single point at the distal end of the petiole; in pinnately compound leaves, a row of leaflets forms on either side of an extension of…

Detailed explanation-3: -A leaf remains attached to the stem through a common stalk known as the petiole. A leaf in which the flat and green lamina part is cut into different smaller leaflets on a common stalk is called a compound leaf. The leaflet present at the very end of the leaf is termed the terminal leaflet.

Detailed explanation-4: -Compound leaf has multiple leaflets that connect to the stem through the petiole and exhibit the whole division of the lamina or leaf blade along the midvein, in addition to the main leaf. The rachis, or modified mid-vein, on which this arrangement may be observed is called rachis.

Detailed explanation-5: -The difference primarily between simple and compound leaves is that in simple leaves there is a single leaf blade and depression that do not split the leaf blade, whereas, in compound leaves, the depression is deep such that it splits the leaf blades into leaflets.
