Current Question (ID: 13074)

Question:

Which is an incorrect statement? I. Each cell of sporogenous tissue in anther is capable of giving rise to microspore tetrad. II. The pollen grain represent male gametophyte III. Pollen grains are usually triangular and 10-15 um in diameter. IV. Sporopollenin is one of the most resistant organic materials which can be destroyed only by strong acids and alkali.

Options:

1. I, II are incorrect but III, IV are correct
2. III, IV are incorrect but I, II are correct
3. I, III are incorrect but II, IV are correct
4. II, IV are correct but I, III are incorrect

Solution:

The pollen grains are spherical and 25-50 um in diameter. Sporopollenin is resistant to strong acids and alkali.
