Reproduction is a distinctive characteristic of Living Organisms. All living organisms have survived and evolved over the centuries by virtue of Reproduction. Living Organisms Reproduce and give rise to similar organisms of the same species. Different organisms have different ways and process of Reproduction. In this chapter, we will learn about the types and processes of Reproduction.
Reproduction is the biological process by which organisms give birth or give rise to a new organism. This process is seen in all living organisms- both plants and animals.
Asexual Mode of Reproduction
Reproduction is the biological process by which new organisms known as the offsprings are produced by their parents. It is of two types: Sexual reproduction and Asexual reproduction. The difference between the two types lies in the number of parents required for both. In Sexual reproduction, two parents are required to give rise to the offspring. In asexual reproduction, a single parent can give rise to the offspring. Asexual reproduction is commonly seen in plants but is less common in the animal kingdom.
Sexual Reproduction in Flowering Plants
Sexual reproduction is the type of reproduction that involves two different parents that belong to the opposite sex. This type of reproduction is seen in both plants and animals. In plants, sexual reproduction occurs in flowering plants. Before we learn more about sexual reproduction in flowering plants, we must understand the anatomy of a flower.
Reproduction in Human Beings
Reproduction in human beings is by sexual reproduction where both the male and female gametes fertilize to give rise to an embryo. The fertilization of human embryo occurs inside the body of the female. Thus, it is called Internal Fertilization. Human Beings are viviparous organisms who give rise to Embryos directly instead of laying eggs. Let us understand a little more about the male and female reproductive organs and the process of fertilization in them.
