Which of the following undergoes meiosis in the development of pollen grains?
|
Microspore
|
|
Megaspore
|
|
Megaspore mother cell
|
|
Microspore mother cell
|
Explanation:
Detailed explanation-1: -In angiosperms, all the sporogenous cells in the anther become microspore mother cells which undergo meiosis or reduction division to form a tetrad or a group of four pollen grains.
Detailed explanation-2: -The process of formation of microspores from a mother cell through meiosis is called microsporogenesis. The microspores, as they are formed, are arranged in a cluster of four cells-the microspore tetrad. As the anthers mature and dehydrate, the microspores dissociate from each other and develop into pollen grains.
Detailed explanation-3: -The process of formation of microspores from pollen mother cell (PMC) through meiosis is called microsporogenesis.
