Question

Embryo sac development in angiosperms can be all, Except

• A. Monosporic
• B. Bisporic
• C. Tetrasporic
• D. Trisporic

Answer 1

The correct option is D Trisporic

Embryo sac is the female gamete of the seed plants which later produces eggs. There are different types of embryo sacs on the basis of the number of megaspore nuclei involved in the development of an embryo, they are:

1. Monosporic - single megaspore nuclei are involved in embryo development.
2. Bisporic - Two megaspore nuclei are involved.
3. Tetrasporic - Four megaspore nuclei are involved.

So, the correct option is 'Trisporic'.
