difference between microsporogenesis and megasporogenesis
Answers
The formation of megaspores inside the ovules of seed plants. A diploid cell in the ovule, called a megasporocyte or a megaspore mother cell, undergoes meiosis and gives rise to four haploid megaspores.
Microspores are spores that are specifically male and give rise to male gametophytes; megaspores, on the other hand, are specifically female and give rise to female gametophytes.
. It is meiotic formation of haploid microspores from diploid microspore mother cell.

ADVERTISEMENTS:
2. The arrangement of microspores in a tetrad is generally tetrahedral.
3. All the four microspores of a spore terad are functional.
4. Micro sporogenesis is found inside microsporangium.
ADVERTISEMENTS:
5. A large number of microspore mother cells are functional in a microsporangium.
Mega sporogensis:
1. It is meiotic formation of haploid megaspores from diploid megaspore mother cell.
2. The arrangement of megaspores in a tetrad is commonly linear.
3. Only one megaspore of a spore tetrad is functional.
4. It is found inside a mega sporangium.
5. Generally a single megaspore mother cell is functional in a mega sporangium.
