Question

• A. Pea
• B. Gram
• C. Castor
• D. Maize

Answer 1

The correct option is D Maize

Maize or corn seed is actually a one seeded fruit called caryopsis or grain. It is a monocot endospermic seed. It consists of following parts:

(i) Seed coat: It is fused with the fruit wall (pericarp). It encloses a kernal which includes embryo and endosperm.

(ii) Endosperm: It constitutes 2/3 of the grain. Endosperm consists of outer aleurone layer and inner starchy endosperm.

(iii) Embryo: It lies on one side of the starchy endosperm and appears to be a lighter oval area in the whole seed.

So, the correct answer is ‘Maize’.
