Question

Defferentaite between microsporophyll and megasporophyll in cycas

Answer 1

microsporophyll :-

1. It bears microsporangia.

2. A micro sporangium contains numerous microspores or pollen grains.

3. Microspores or pollen grains are not retained. They are always shed.

4. The male gametophyte is formed near the female gametophyte.

5. In angiosperms, the microsporophyll is modified into stamen.

megasporophyll

1. Megasporophyll bears mega sporangia.

2. A mega sporangium usually bears one functional megaspore.

3. In seed plants, the megaspore is retained inside the mega sporangium.

4. In seed plants, the female gametophyte is produced inside the mega sporangium. Ferti­lisation and embryo formation occur there.

5. In angiosperm, the megasporophyll is rolled to produce a carpel.

hope helps ☺️☺️☺️

Answer 2

Microsporophyll bears spores that grow into male gametophytes.
The microsporophylls located just inside the petals, are the Stamens.

Megasporophyll bears spores that grow into female gametophytes.
The megasporophylls located just inside the stamens, are the Carpels.
