Class 12 Biology Chapter-01: Reproduction in Organism
Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. The offspring grow, mature and in turn produce new offspring. Thus, there is a cycle of birth, growth and death. Reproduction enables the continuity of the species, generation after generation. You will study later in Chapter 5 (Principles of Inheritance and Variation) how genetic variation is created and inherited during reproduction.

Reproduction is a biological process of the formation of new offspring from pre-existing organisms. It ensures continuity of species generation after generation as older individuals undergo senescence, and ultimately they die.
Life span – The period from birth to the natural death of an organism represents its life span. The life span of organisms varies from a few days (Butterfly-1to 2 weeks) to thousands of years (Banyan tree). Reproduction becomes a vital process without which species cannot survive for long.
Types of Reproduction: Based on whether there are one or two organisms taking part in the process of reproduction
1. ASEXUAL REPRODUCTION
2. SEXUAL REPRODUCTION
Modes of Asexual Reproduction
1. Usually followed by organisms with relatively simpler organizations.
2. Offsprings produced by a single parent.
3. With/without the involvement of gamete formation.
4. Offsprings produced are genetically and morphologically similar to each other and the parent, i.e., clones.
In Protista and Monera, the parent cells divide into two to give rise to new individuals. Thus, in these organisms, cell division is the mode of reproduction itself.
>Binary fission– in this method of asexual reproduction, a cell divides into two halves and rapidly grows into an adult—Ex- amoeba, paramecium.
> Budding– small buds are produced that remain attached initially with parents and get separated on maturation.
