Question

Transition to land habit of archegoniate

Answer 1

Hot, dry areas, for example, are often covered in hot deserts. Warm, wet regions may give rise to tropical rain forests. There are 10 main types of land habitat on Earth. ... The animals and plants that live in each habitat are adapted to cope with the conditions around 

Answer 2

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.
