Question

Intine and exine layers of pollen grain are made up of which of the following substances?

• A. Pectocellulose- sporopollenin respectively
• B. sporopollenin- pecto cellulose respectively
• C. pectocellulose- chitin respectively
• D. chitin- sporopollenin respectively

Answer 1

The correct option is A Pectocellulose- sporopollenin respectively

The pollen is made up of two layers:-

1. Exine which is made up of a most resistant organic chemical sporopollenin and it the outer layer.
2. Intine which is the inner layer is made up of cellulose and pectin.

So, the correct option is 'Pectocellulose- sporopollenin respectively'.
