Question

differentiate between microsporogenesis and megasporogenesis

Answer 1

Microsporogenesis 
1. It is meiotic formation of haploid microspores from diploid microspore mother cell.
2. The arrangement of microspores in a tetrad is generally tetrahedral. 
3. All the four microspores of a spore tetrad are functional.

Megasporogenesis
1. It is meiotic formation of haploid megaspore from diploid megaspore mother cell.
2. The arrangement of megaspores in a tetrad is commonly linear. 
3.Only one megaspore of a spore tetrad remains functional, other three degenerate.
