Leaflets are a characteristic of ________ leaves.

a. alternate

b. whorled

c. compound

d. opposite

Leaves are the main sites for the process of photosynthesis. In this process, plants synthesize their food. Most leaves are of green color because of the pigment called chlorophyll that gives the greenish color to leaves. Other pigments like carotenoids, xanthophyll usually give different colors to some leaves other than green.

Phyllotaxy is the arrangement of leaves on the stem. Leaves can be categorized as having simple or compound structures. Simple leaves are those leaves that are having an undivided blade even if it is lobed. In a compound leaf, leaflets are formed due to the complete division of the leaf blade as in the locust tree. The leaflets generally have their stalk but are attached to the rachis.

The alternate leaves are arranged alternatively on both sides of the stem.

A whorled type of arrangement is seen where three or more than three leaves are attached to one node.

In opposite arrangements two leaves arise from a single point but are connected oppositely to each other.

Therefore, option ‘c’ is the correct answer.

Compound leaves possess leaflets where the complete division of leaf blades is found.
