Question

what is reproduction​

Answer 1

Reproduction:

• Reproduction is the production of offspring ( the biological process by which new individual organisms are produced from their parents).
• There are two main forms: sexual and asexual reproduction.
• In sexual reproduction is a type of reproduction that involves the production of offspring by the fusion of male and female gametes.
• In asexual reproduction, one parent copies itself to form a genetically identical offspring. Asexual reproduction is not limited to a single-celled organism.
• The process involves rapid population growth and no mate is required for the process. Asexual reproduction is further divided into:

                           Binary Fission

                           Budding

                           Fragmentation

                           Sporogenesis.

Answer 2

Reproduction: It is the process by which a living organism is able to produce new individuals of its own kind. Unlike other life processes such as nutrition, respiration, etc ., it is not essential to maintain the life of an individual organism. But it is for the existence and continuity of the species.

Explanation:

• Reproduction involves the creation of DNA copy and additional cellular apparatus by the cell involved in the process.
• The process of DNA copying leads to variations. This inbuilt tendency for variations during reproduction is the basis for evolution.

Living organisms reproduce mainly through :

1. Asexual reproduction
2. Sexual reproduction

Asexual Reproduction

• single celled organism reproduce through following ways :

1. Fission
2. Budding
3. spore formation

• Reproduction by multicellular organisms

1. Fragmentation and regeneration
2. vegetative propagation

Sexual reproduction

• Sexual reproduction involves two individuals.
• reproduction begins with fertilization, which is defined as the union of two different gametes. The motile germ-cell ( pollen or sperm) is called male gamete and germ-cell containing stored food ( egg or ovum ) called female gamete. The process of fusion of two gametes is called fertilization. After fertilization, a zygote is formed, which develops into a new organism.
