Production of a new organism from an existing organism (parent organism) of the same kind is called reproduction.
The process involves the creation of a neworganism that is essential for the survival of a particular species.
Reproduction is necessary for the continuation of the species to maintain the continuity of the species across various generations. The new organism is called the young one.
Cats reproduce by giving birth to kittens. Dogs reproduce to give birth to puppies, and hens reproduce to give birth to chicks.
Reproduction and it's types:
Types of reproduction
The two modes of reproduction are :
- Sexual reproduction
- Asexual reproduction
The two gametes - male and female gamete fuses together to form a new cell called the zygote. Zygote grows and develops into a new organism. The male and female parents have male and female reproductive organs that produce the male and female sex cells or gametes.
Production of a living organism by the fusion of gametes or sex cells is called sexual reproduction.
In a male, the gametes or the sex cells are called sperms, while the female gametes or the sex cells are called eggs or ovum.
Dog, cat, fish, frog, and humans reproduce through sexual reproduction.
Production of a new offspring that involves only a single parent without the involvement of sex cells is called asexual reproduction.
It is called asexual reproduction as it does not involve the sex cells for the production of a new organism. The young ones that are produced is an exact copy of the parent.
Binary fission in Amoeba and Euglena
Budding in Hydra and Yeast
Spore formation in Fungi like Mushroom
Fragmentation in Spirogyra and Planaria
Different forms of asexual reproduction: Binary fission, Budding, Fragmentation, Spore formation, Regeneration
