Explanation:
Heterospory in Plants:
- Heterospory is a reproductive strategy in plants where they produce two distinct types of spores - microspores and megaspores.
- Microspores develop into male gametophytes, which produce male gametes (sperm).
- Megaspores develop into female gametophytes, which produce female gametes (eggs).
Example of Heterosporous Plants:
- Genera like Selaginella and Salvinia are examples of heterosporous plants because they produce both microspores and megaspores.
Characteristics of Heterosporous Plants:
- Heterosporous plants have separate male and female reproductive structures, which increases the chances of successful fertilization.
- This reproductive strategy is more advanced compared to homospory, where plants produce only one type of spore.
Therefore, plants like Selaginella and Salvinia are classified as heterosporous due to their ability to produce both microspores and megaspores, leading to the development of male and female gametophytes.
