Answer 2

Reproduction can be of two types-

Sexual reproduction
Asexual reproduction
These two modes of reproduction have given birth to all life forms.

Sexual Reproduction

It is the mode of reproduction in which sex cells from two organisms, one male and one female, combine to form a singular zygote.

Sexual Reproduction in Plants

Plants that reproduce sexually have sex parts which we know as flowers. The process of reproduction involves the fusion of male gametes, namely, pollen with the female gamete, also known as ovules. This fusion results in the formation of a zygote and an endosperm nucleus, which grow into seeds and fruits respectively.

Sexual Reproduction in Animals

Among the different modes of reproduction in animals, sexual reproduction is the most common one. Most animals reproduce sexually, though in a variety of different ways.

Sexual reproduction in animals involves the union of a haploid sperm and a haploid egg to form a diploid zygote, which shares its DNA with both the parent cells.

Asexual Reproduction

It is the mode of reproduction which involves only one organism. The offspring that is produced is genetically identical to the mother and almost always has the same number of chromosomes.

Asexual reproduction in plants

Some plants have the ability to reproduce asexually, that is, without the help of flowers or pollens. There are different modes of asexual reproduction in plants, both natural and human induced.

Asexual reproduction in animals

Some simple animals, many of whom are single celled, reproduce asexually.
