Question

Equal amount of sunlight is received on all sides by

• A. Unipinnate leaf
• B. Palmately compound leaf
• C. Isobilateral leaf
• D. Dorsiventral leaf

Answer 1

The correct option is C Isobilateral leaf

A. Unipinnate leaf- The leaflets are directly borne on the rachis (midrib). They are usually borne in opposite or sub- opposite pairs.

B. Palmately compound leaf- In this, the individual leaflets radiate in a digitate pattern from a very short rachis.

C. Isobilateral leaf- The leaves in which upper and lower surfaces are similar are called isobilateral.

D. Dorsiventral leaf- The leaves which possess distinct dorsal and ventral surfaces are called dorsiventral.

Sunlight is essential for photosynthesis. Proper sunlight is received by isobilateral leaf as they are placed parallel to the main axis and are also parallel to the sun rays.

Hence, the correct answer is 'Isobilateral leaf'.
