Microsporangiate is also called male strobili because they contain microspores that form male gametophyte

Gametophytes can’t exist independently i.e. free living

Microsporangiate and microsporangia exist within the same plant

3. Which among the following is incorrect?

13. Which among the following is incorrect?

The reduced male gametophyte is termed as pollen grains

Pollen grains may be monosaccate, disaccate, trisaccate or non-saccate

Megasporangium tissue is soft and non-woody

After mitosis, a megaspore forms female gametophyte with two or three archegonia that undergoes fertilization
