During the gametophyte phase in bryophytes
WebNov 6, 2024 · The life cycle of bryophytes shows two distinct phases sucb as a haploid gametophytic phase and a diploid sporophytic phase alternating with each other The adult plant body represents the gametophyte. A short-lived sporophyte occurs as a parasite on the gametophyte. It is the adult plant body in bryophytes. WebBryophyta is a division of non-vascular terrestrial plants. They consist of mosses, liverworts and hornworts. They are commonly found in moist and shady places. Bryophytes need water to complete their life cycle, so they are also called amphibians of plants. 1. Which among the following is also known as bog moss? (a) Riccia (b) Sphagnum
