Text Solution

Verified by Experts
The correct answer is:
C

Seed habit refers to the evolutionary development of seeds in plants.

The most important step toward seed formation is heterospory.

• Heterospory means production of two types of spores:

• Microspores → develop into male gametophyte

• Megaspores → develop into female gametophyte

This separation allows:

Retention of the megaspore within the parent plant

Protection and nourishment of the developing embryo.
