Read the following statements carefully: A. Sporogenous tissue occupies the centre of each microsporangium and is composed of haploid cells. B. Each cell of the sporogenous tissue is a potential pollen mother cell (PMC). C. The PMCs undergo mitotic divisions to form microspore tetrads. D. As the anthers mature and dehydrate, the microspores dissociate from each other. How many of the above statements are incorrect?

Step-by-step solution

Statement A is incorrect because sporogenous tissue is composed of diploid cells, not haploid cells. Statement B is correct as each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad, thus acting as a potential pollen mother cell (PMC). Statement C is incorrect because PMCs undergo meiotic (not mitotic) divisions to form microspore tetrads. Statement D is correct as the dehydration of anthers is the physical trigger for the dissociation of microspores from the tetrad. Therefore, exactly
