Microsporogenesis

Megasporogenesis

1. Formation of microspores and production of male gametophyte is termed micro-sporogenesis.

2.. It occurs inside the microsporangia or anther.

3. Many microspore mother cells are differentiated in a microsporangium.

4. All the four cells of the microspore tetrads are functional.

1. Formation of megaspores , female gametophyte from megaspore mother cells is called megasporogenesis.

2. It occurs in the nucellus of the ovule/megasporangium.

3. Only one megaspore mother cell is differentiated in a megasporangium.

4. Only one of the four cells in the megaspore tetrad continues to grow.
