Microsporogenesis and megasporogenesis differ in the following ways:
Microsporogenesis | Megasporogenesis |
The process by which microspore mother cells divide and produce pollen grains is known as microsporogenesis. |
Megasporogenesis is the process by which megaspore mother cells are formed and differentiate into megaspores by meiosis. |
Located within the pollen sac of the anthers. |
It is present in the nucellus of the ovule. |
A pollen grain produced by a microspore mother cell functions properly. |
The megaspores have only one functional megaspore. |
Results in the formation of pollen grains (male gametophyte) |
Resulting in the formation of embryo sacs (female gametophyte) |
Microspore mother cells and megaspore mother cells are every diploid, as they have two sets of chromosomes |
The mother cells for megaspores and microspores enlarge and undergo meiosis in order to produce four haplotypical cells called megaspores and microspores, respectively. |
