Question

The spore germinate to produce a haploid gametophyte called?

Answer 1

Dear student,
The main plant of Pteridophytes are sporophytes. They reproduce asexually by forming spores in sporangia. The plants may be homosporous, i.e., produce only one type of spores (e.g., Lycopodium, Pteridium) or heterosporous i.e., produce two different types of spores, smaller microspores and larger megaspores (e.g., Selaginella, Marsilea etc.).

The spores germinate to produce haploid gametophyte, called as prothallus. The homosporous Pteridophytes produce bisexual (monoecious) gametophytes, whereas heterosporous one produce unisexual (dioecious) gametophytes.
