Differentiate between the following.
Apogamy and Apospory
Apogamy:
- Formation of haploid sporophytes from haploid cells of gametophytes without fusion of gametes.
- It is a type of asexual reproduction discovered by Farlow in Pteris.
Apospory:
- Formation of diploid gametophyte from diploid cells of the sporophyte (which do not undergo meiotic cell division).
- This was discovered by Druery in fern Athyrium.
Apogamy
Apospory
1. Apogamy is a type of fern reproduction in which the sporophyte develops from the gametophyte without any gamete fusion.
1. Apospory is the improvement of 2n gametophytes from vegetative, or non-reproductive, cells from the sporophyte, without meiosis or spores.
2. Apogamy, on the other hand, is the formation of an embryo without fertilisation, particularly the formation of some ferns from a gametophyte without fertilisation.
2 .Apospory is the development of a gametophyte from a sporophyte without the need for meiosis or the formation of spores.
3. Because there is no fusion of gametes in this case, the gametophyte and sporophyte are both haploid.
3.Because there is no meiosis, the sporophyte and gametophyte are both diploid.
4. Apogamy is visible in Funaria.
4. Apospory can be seen in anthoceros.
5. Apogamy is when one sporophyte develops into another..
5. Apospory is the development of two gametophyte.
6. It lacks gametes and relies on vegetative cells for syngamy
6.There is no meiosis and spore.
