Jan 24, · The fully grown sporophyte, what the layman refers to as the fern, produces genetically unique spores in the sori by meiosis. The haploid spores fall from the sporophyte and germinate by mitosis, given the right conditions, into the gametophyte stage, the prothallus. The Sporophyte Generation In a plant there is always, at some time during the life cycle, a multicellular adult organism whose cells contain diploid nuclei. These adults are called sporophytes. At maturity, specialized cells (usually called sporocytes or spore mother cells) within the sporophyte .
Which part of the pine life cycle is an adult sporophyte? An adult sporophyte is at the diploid stage. 2. Which part of the pine life cycle is the male gametophyte? The female gametophyte? In both male and female pine life cycle, mitosis the life cycle. 3. Where does fertilization occur and . The character and relative extent of the two phases vary greatly among different groups of plants and algae. Over the course of evolution, the gametophyte stage has become progressively bizard.xyz, the gametophyte stage is dominant in the more primitive (nonvascular) plants (), whereas the sporophyte is the dominant phase in the life cycle of higher (i.e., vascular) bizard.xyzg: adult.
In pteridophytes, the main plant body is a sporophyte which is differentiated into true root, stem and leaves and gametophyte is small or inconspicuous, and it is usually independent. Gymnosperms and Angiosperms do not produce spores. Hence the correct option is A. Answer verified by Toppr. OUROBOROS is a master regulator of the gametophyte to sporophyte life cycle transition in the brown alga Ectocarpus Susana M. Coelho a,b, Olivier Godfroy, Alok Arun, Gildas Le Corguilléc, Akira F.
