Question

What is actual difference between sporophyte and gametophyte?

What is the actual difference between spore and gametes?

What is difference among haplontic ,diplontic and haplo-diplontic?

Answer 1

Answer:

1. Gametophytes are haploid (n) and have a single set of chromosomes, whereas Sporophytes are diploid (2n), i.e., they have two sets of chromosomes. ... A sporophyte reproduces asexually and a gametophyte sexually. Significance: For a diploid (2n) sporophyte to produce haploid (n) spores, the cells have to undergo meiosis.

2. One difference is in the type of reproduction that each are involved in. Spores are used in asexual reproduction, while gametes are used in sexual reproduction. ... A gamete has to fuse with another gamete before it can form a zygote that then can grow into the adult sporophyte.

3. Definition. Haplontic life cycle refers to a life cycle in which the main form is haploid, with a diploid zygote being formed only briefly while diplontic life cycle refers to a life cycle in which the main form, except for the gametes, is diploid.
