Answer:
• Life cycle of a plant is called alternation of generations. • Haploid and diploid age exchanging during life cycle - Sporophyte ie. Multicellular , spore framing diploid plant structure. Gametophyte ie. Multicellular haploid plant structure, frames gametes.
3. Rotation of ages in various plants • Depends on kind of plant • Bryophytes(mosses and greeneries) - overwhelming age haploid stage - principle plant body is made out of gametophyte • Pteridophytes and gymnosperms - predominant age diploid stage - fundamental plant body is made out of sporophyte.
4. Importance: • Better possibility for survival • Better adjusted to condition • Newer assortments create • Variations are delivered during meiosis.
5. Variation of age in Bryophytes • Haploid stage is gametophytic age or sexual stage. • Bears regenerative organs - produce antherozoids and eggs • Gametophytic organize - longer lived ,obvious when contrasted with sporophyte. • Gametophytic stage is predominant in life cycle.
