Question

Are Pteridophytes haplodiplontic?

Answer 1

Haplodiplontics:

1. This life cycle involves the clear alternation of generation between a haploid gamete-producing gametophyte and a diploid spore-producing sporophyte.
2. Both are multicellular and free-living and either phase is dominant.
3. Haplodiplontic is a type of plant life cycle seen in the Pteridophytes and Bryophytes.
4. The sporophyte of Pteridophytes is the independent and free-living dominant stage which is replaced by a short-lived gametophyte.
5. The sporophyte (diploid) undergoes meiosis to form spores (haploid).
6. Examples: Kelps, Ectocarpus, Ulva.
