Make outline diagram of different types of life cycle in algae
Hey,
The process involving growth and development leading to different morphological and cytological changes is referred as Life Cycle.
Algae basically comprises of five different types of Life Cycle,
- Haplontic Life Cycle:
Gametophyte (n) ---->Gametes-(n)---> Fusion of Gametes to form Zygote (2n)-----> Meiosis in Zygote to form Haploid Zoospores (n).
- Diplontic Life Cycle:
Gametes (n) -----> Zygote (2n)-----> Mitosis in Zygote to form Sporophyte ( 2n)
-Haplo- Diplontic Life Cycle:
Gametes (n) -----> Zygote (2n) -----> Mitosis to form Sporophyte-(2n) ---> Meiosis in Sporophyte to form Zoospores ( n).
- Haplobiontic Live Cycle:
Gametes(n) ---> Zygote-(2n)-->Meioisis in Zygote to form Carposporophyte(n) ----> Carpospores(n).
- Haplo-diplontic Life Cycle:
Gametophyte (n) -> Gametes(n) -> Fusion to form Zygote (2n) -> Mitosis to form Carposporophyte( 2n) -> Carpospores( 2n) -> Tertrasporophyte( 2n) -> Meiosis to form Tetraspore (n).
Above are the fives stages in the life cycle of algae.
note: 'n' represents haploid nature
'2n' represents diploid nature.
Hope that helps.
Thank you
