Final Answer:
Large megaspores, which develop into female gametophytes, are characteristic of heterosporous plants.
Step-by-step explanation:
Heterospory is a reproductive strategy observed in certain plants where the production of two types of spores occurs—megaspores and microspores. Megaspores are larger and develop into female gametophytes, while microspores are smaller and give rise to male gametophytes. This reproductive adaptation is commonly found in seed plants, including gymnosperms and angiosperms.
In heterosporous plants, megaspores are typically larger in size compared to microspores. After germination, a megaspore develops into a female gametophyte, which is the structure responsible for producing eggs. This reproductive strategy enhances genetic diversity and is a key evolutionary development in the plant kingdom.
