Correct Statements Regarding Gametophyte in Pteridophytes:
Three
- Small, inconspicuous: The gametophyte in pteridophytes is indeed small and inconspicuous, often being less prominent than the sporophyte stage.
- Mostly photosynthetic thalloid or saprophytic: The gametophyte in pteridophytes is mostly photosynthetic, deriving energy through photosynthesis. It can also be saprophytic, depending on the species.
- Short lived, haploid: The gametophyte in pteridophytes is short-lived and haploid, as it is the haploid stage in the life cycle of these plants. It produces gametes through mitosis to fertilize and form the diploid sporophyte.
Therefore, three statements are correct regarding the gametophyte in pteridophytes.
