Question

Why is reproduction essential for organisms?

Answer 1

Hint: Reproduction is a biological process where parents produce new organisms which are called as offsprings, where they carry some features of parents both in phenotype and genotype.

Complete answer:
Reproduction is mainly to continue the species on the earth, if there are no individual reproduction organisms extinct soon, so for the existence of species, and at the same time to maintain the balance in ecosystem reproduction plays a vital role.

Importance of reproduction
- To maintain the species of both plants and animals
- To keep the number of individuals, which means reproduction always replaces the old dead individuals.
- It is helpful to transfer the genes from parents to young individuals
- It is also essential for evolution

Before life begins there are so many chemical reactions happening and being developed in the form of single cells; later these single cells produce more new individuals by process of replication which results in the development of multicellular organisms. After that, the process of reproduction completely changed in multicellular organisms which influence some other things like hormones etc., so evolution will happen only when there is a reproduction

> Types: Mainly, reproduction is classified into two types.
- Asexual reproduction
- Sexual reproduction

Asexual reproduction: In this type, it involves only a single parent, there is no mixing of genetic material takes place. Examples are unicellular organisms such as paramecium, hydras where they reproduce by a process called budding.

Sexual reproduction: In this type, it involves two parents, and there is a mixing of genetic material from maternal and paternal, so genes are transferred
Sexual reproduction is an advanced type of reproduction as the genetic material from both parents are heridited into offspring.
Example is humans
