NCERT Solutions for Class 8 Science Chapter 6 Topics

6.1 Modes of Reproduction: As discussed in reproduction of animals class 8 science chapter 6 ncert solution, Reproduction is the process of creating new members of the same species. There are two primary ways of reproduction: sexual reproduction and asexual reproduction.

6.2 Sexual Reproduction: As discussed in reproduction of animals class 8 science chapter 6 ncert solution, in animals, males and females have different reproductive parts or organs. Just like in plants, the reproductive parts in animals also create gametes that fuse together to create a zygote, the zygote that develops into a whole new individual. This type of reproductive process begins from the fusion of the male and female gametes. This fusion of gametes is known as sexual reproduction. 

Following subtopics will be discussed in the section 6.2 sexual reproduction: 

• Male Reproductive Organs

• Female Reproductive Organs

• Fertilisation

• Development of Embryo

• Viviparous and oviparous animals

• Young ones to adults

6.3 Asexual Reproduction: As discussed in reproduction of animals class 8 science chapter 6 ncert solution, Asexual reproduction is the process of creating offspring without the use of gametes, or the combination of genetic material from both parents. A single parent organism can produce genetically identical offspring, called a clone, in this mode. Asexual reproduction tends to be less complicated than sexual reproduction, and can be beneficial in stable and predictable conditions.

Following subtopics will be discussed in the section 6.3 Asexual Reproduction:

• Budding

• Binary Fission

Key Features of Class 8 Science Chapter 6

• There are two ways of reproducing in animals: sexual reproduction and asexual reproduction. 

• Sexual reproduction involves the fusion of a male and a female’s gametes. In females, the reproductive organs are ovaries and uteruses. 

• In males, the reproductive organs include testes, sperms and penises. The ovaries of females produce female gamets called ova, while the testes of males produce male gamets called sperms. 

• The fusion of the ovum and the sperm is referred to as fertilisation, and the fertilized egg is called “zygote”. Internal fertilisation occurs inside the female’s body, and is observed in humans, other animals and dogs.

• External fertilisation takes place outside of the female body. This is what we see in frogs, fishes, starfish etc.

• Zygotes divide repeatedly to give birth to an embryo. The embryo gets inserted into the uterine wall for further growth.

• The stage of an embryo where all the body parts are visible is called a fetus.

• Animals like humans, cows and dogs that give birth to babies are called viviparous animals. 

• Animals like chickens, frogs, lizards and butterflies, which lay eggs, are called oviparous animals. 

• The larva changes into an adult through drastic changes called metamorphosis

• Asexual reproduction takes place when only one parent is involved. This is asexual reproduction.

• In hydra, new organisms form from buds. This is called budding.

• An amoeba divides itself into two to reproduce. This is called binary fission.
