Question

what is heterospory??
lengthy answer required plz​

Answer 1

Explanation:

Develpoment of two types of spores is known as heterospory and the plants are known as heterosporous. Megaspores produce female gametophyte while microspore produce male gametophyte. In seed bearing plants the gametophytes produced by megaspores and microspores are very small and never released from the spores. This protects the gametophytes from desiccation which is a very important evolutionary advancement.

Answer 2

Answer:

Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. The smaller of these, the microspore, is male and the larger megaspore is female.

Producing two types of spores differing in size and sex, the male microspore and the female megaspore, which develop into separate male and female gametophytes. All seed-bearing plants, as well as some ferns and other seedless plants, are heterosporous. Compare homosporous.
