| Read the passage given below and answer the following questions. |
| As the anther develops, the cells of the sporogenous tissue undergo meiotic cell divisions to form microspore tetrads due to callose. As each cell of the sporogenous tissue is capable of giving rise to a microspore tetrad. Each one is a potential pollen or microspore mother cell. The process of formation of microspores from a pollen mother cell through meiosis is called microsporogenesis. The microspores or pollen grains (n), as they are formed, are arranged in a cluster of four cells- the microsporetetrad i.e., tetrahedral due to callose. As the anthers mature and dehydrate, the microspores dissociate from each other due to callase and develop into pollen grains (n). Inside each microsporangium several thousands of microspores or pollen grains are formed that are released with the bursting of anther. |
