Question
Differentiate halpontic and diplontic life cycle.
Solution 1
| Haplontic life cycle | Diplontic life cycle | |
| Gametophyte phase | Dominant photosynthetic independent Recessive represented by the zygote. | Recessive represented by single to few celled stage. |
| Sporophytic phase | Zygote undergoes meiosis to restore haploidy. | Zygote develop in to dominant sporophyte. |
| e.g. Volvox.Spirogyra | e.g. Fucus, Gymnosperm, Angiosperm. |
Solution 2
- Halpontic cycle:
- Gametophyte is dominant
- Sporophyte is represented by zygote
- Diplontic cycle:
- Sporophyte is dominant
- Gametophyte is represented by few cell gametophyte
