Question

Selaginella has a tendency to form seed, called seed habit, because it follows

• A. Retention of megaspore permanently inside the megasporangium
• B. Heterospory
• C. Both above characters
• D. None of the above

Answer 1

The correct option is A Retention of megaspore permanently inside the megasporangium

Selaginella is a genus of primitive vascular plants in the family Selaginellaceae. Selaginella has a tendency to form seed because the retention and germination of single megaspore within megasporangium to form a female gametophyte led to the phenomenon of seed habit, a characteristic feature of spermatophytes.

So, the correct answer is 'Retention of megaspore permanently inside the megasporangium'.
