Heterospory, i.e., formation of two types of spores-microspores and megaspores is a characteristic feature in the life cycle of a few members of pteridophytes and all spermatophytes. Do you think heterospory has some evolutionary significance in plant kingdom?

Explanation

### Step-by-Step Solution:

1. **Definition of Heterospory**:
- Heterospory refers to the production of two distinct types of spores in plants: microspores and megaspores. Microspores develop into male gametophytes, while megaspores develop into female gametophytes.

2. **Comparison with Homospory**:
- In contrast to heterospory, homospory is the condition where only one type of spore is produced. This is typical in bryophytes, where all spores are identical.
