- Characteristics similar to two parent organisms.
(9) How are the modes for reproduction different in unicellular and multicellular organisms?
Answer :
In unicellular reproduction happens through fission, fragmentation, regeneration, Budding. In these the parent cell divides itself into two or more cells.
But in multicellular organisms reproduction occurs through vegetative propagation, spore formation. In these different organs is specialized for production of new organisms. In human and animals sexual reproduction is done by sexual intercourse and special organs develop egg cells for new organisms to produce.
(10) How does reproduction help in providing stability to populations of species.
Answer :
Reproduction is necessary for organisms to be in existence, we notice organisms because of their population. If organisms didn’t reproduce it is sure that their existence will become history. It helps in keeping species for next generation and maintaining stability by maintaining the rate of death and birth.
