Reproduction is the process of continuation of species. It is the process by which new organisms are formed.
It is necessary because of the following reasons-
1. for the continuation of species
2. For the formations of new organisms
3. For the continuation of the life on earth
4. To maintain the life chain
5. To pass on the genes
Organisms can reproduce by two ways-
1. Asexual
2. Sexual
ASEXUAL REPRODUCTION- In this process only a single parent is involved and no gamete formation takes place.
For example- Amoeba, Yeast , Hydra etc.
There are different types of Asexual Reproduction and they are-
1. Budding
2. Fission
3. Vegetative Propagation
4. Regeneration
5. Spore formation
SEXUAL REPRODUCTION- In this process two parents are involved and gamete formation takes place.
For example- Humans, Animals
Reproductive organs of the organisms are required for this type of reproduction.
