Hope that was helpful.Thank you! Some diploid cells in the sporangium expand and form elateres (tubular cells with spiral-like thickenings) that contribute to the dissemination of the spores. Haploid kommer från grekiskans haploos vilket betyder "enkel". En haploid cell har en enkel uppsättning kromosomer. [2] Uttrycket används om könscellerna hos arter som har sexuell fortplantning. [1] Dessa organismer alternerar mellan tillstånd med enkel kromosomuppsättning (haploid) och dubbel kromosomuppsättning (diploid).

Within the sporophyte, meiosis occurs producing haploid spores. These spores are dispersed and grow into the small haploid gametophyte, AKA the prothallium. True ferns The best known stage of the life cycle of true ferns is that of the mature diploid sporophyte.

Some diploid cells in the sporangium expand and form elateres (tubular cells with spiral-like thickenings) that contribute to the dissemination of the spores. Fertilization (syngamy) is the fusion of two haploid gametes (the sperm and the egg) to form a diploid (2n) zygote. This is how the chromosome number in a life cycle changes from haploid (n) to diploid (2n). The biflagellate sperm in the above illustration is characteristic of a moss. Human sperm have … Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.
