EzraMicrospores are produced in the male reproductive structures (microsporangia) of plants and develop into male gametophytes, while megaspores are produced in the female reproductive structures (megasporangia) and develop into female gametophytes. Microspores are smaller in size compared to megaspores.

Is selaginella a homosporous or a heterosporous plant?
Selaginella is a heterosporous plant, meaning it produces two types of spores – megaspores and microspores. Megaspores develop into female gametophytes, while microspores develop into male gametophytes.
Is a stamen the site where microspores are produced?
Yes, a stamen is the male reproductive organ of a flower that produces pollen grains containing microspores. The microspores develop into male gametophytes.
Will megaspores divide to form the female gametophyte or the sporophyte?
Megaspores will divide to form the female gametophyte.
What is magaspore?
A megaspore is a type of haploid spore produced by some plants that develops into a female gametophyte during sexual reproduction. It is typically larger than microspores, which develop into male gametophytes. Megaspores are an important part of the life cycle of plants that reproduce through alternation of generations.
What is heterospory?
Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. Heterospory was evolved from isospory independently by several plant groups in the Devonian period as part of the process of evolution of the timing of sex differentiation. Heterosporic plants produce small spores called microspores which either germinate to become male gametophytes or have reduced male gametophytes packaged within them, and similarly larger spores called megaspores that germinate into female gametophytes, or which have female gametophytes packaged within them.
