Answer:
Explanation:
Gametes are able to survive extensive heat and radiation. The gametes have storage tissue that supply nutrients needed, sustain growth and protective coat this hardened tissue prevent dessication i.e dryness through loss of water and maintain its water level. Abscissic acid helps keep the plant in shape if desssication occur. Ability to regulate fluid helps maintain heat.
d. disperse offspring through both time and space, seeds are disperse via diverse means such as insect, wind, mechanical transport. The protective covering on the seeds help them to last longer and protect damage to the cells till they get a favourable condition to establish and grow. Hence offspring can be disperse in space and time.
Seeds contains endosperm which are food reserves for developing embryo. In seeds adequate nutrients required for growth are supplied for gamete to survive
Alteration of generation occur in plant where a multicellular gametophyte that has n chromosome i.e haploid chromosome will alternates with
A diploid sporophyte with 2n chromosome this two then fuse to products a gametes.
Hence, A,B,D,E are correct
but c. hydrodynamic locomotive forces and variable gametophyte generation is not correct because Locomotive forces and variable gametophytic generation in seed plants do not often occur. Gametophytes produces pollen and embryo sacs.
Answer:
in explanation
Explanation:
I'd say one species can become two different species by mating. If one species mates with a different species than they carry their genes over to the baby. This would become a repeating cycle making another species.
I don't know if this was the answer you were looking for, but this how animal breeders get a certain type of animal.
I would include
- The nucleus: contain genetic info
- Lysosome: clean up things
- Mitochondria: ATP factory
- Ribosome: make protein
- Cell membrane and Cell Wall: maintain and shape the cell etc
