How can Organisms Reproduce?
Organisms can reproduce in the two following ways:
- Sexual Reproduction
- Asexual Reproduction
Asexual Reproduction
Asexual reproduction is a type of reproduction where a new offspring is being produced from single parents. It doesn’t perform any fertilization or fusion of gametes. This type of reproduction can be seen in unicellular organisms like amoeba, worms, and hydra. No or less variety of offspring are being produced as in asexual reproduction only one parent is involved. Some of the ways in which asexual reproduction takes place are- Fragmentation, budding, and fission.
Sexual Reproduction
Sexual reproduction refers to a reproduction in which a new offspring is being produced from the combination of two different individual of different sexes. In this type of reproduction two parents are involved by the fusion of male and female gametes. It performs fusion of gametes. It can be seen in multicellular organisms like humans, animals and so on. Variety of offspring are formed due to involvement of two parents.
Do Organisms Create Exact Copies of Themselves? – Class 10 Notes
Organism consists of similar body structure. The DNA molecules that are found in the chromosome in the nucleus of the cell are responsible for the transfer of characters from the parents to the offspring. During the process the sexual reproduction these cells produce two copies of DNA which further separate into two cells. These two DNA copies will not be identical to each other but they consist of some similarities. Therefore these two organisms will have some variation from their parents.
