Tetragonal anther consists of
1 Two microsporangia
2 Four microsporangia
3 Three microsporangia
4 Five microsporangia
Explanation:
The anther is a four-sided (tetragonal) structure consisting of four microsporangia located at the corners, two in each lobe.

In plants meiosis occurs in
1 Root tip
2 Anther
3 Cambium
4 Pollen grains

Microsporogenesis occurs
1 On margins of leaves.
2 Inside the ovule.
3 Inside the anther.
4 In non- essential floral organs.
Explanation:
Microsporogenesis is the process of formation of microspores or pollen grains, from a pollen mother cell through meiosis is micro sporogenesis Each cell of sporogenous tissue serve as microspore mother cell (MMC). These MMCs undergo meiosis and form microspore tetrad and become haploid, microspores or pollen grains. As anthers mature microspores of the tetrad separate from each other and develops into pollen grains. Each microsporangium contains numerous pollen grains which are released after dehiscence of anther wall.
