Question

difference between microsporogenesis and megasporogenesis

Answer 1

The formation of microspores inside the microsporangia (or pollen sacs) of seed plants. A diploid cell in the microsporangium, called a microsporocyte or a pollen mother cell, undergoes meiosis and gives rise to four haploid microspores.



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. 

Answer 2

. 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.
