NCERT CBSE Class 8 Science Chapter 9: Important Topics
NCERT Solutions for Class 8 Science Chapter 9-Reproduction in Animals explains all the fundamental concepts of this chapter interactively. Several reproduction-related concepts have been illustrated with various diagrams and activities. It helps you to understand all concepts thoroughly and in a very natural way.
Some significant concepts covered in CBSE NCERT Class 8 Chapter 9 are as follows.
In this portion of NCERT Solutions for Class 8 Science Chapter 9-Reproduction in Animals, you will get detailed knowledge about various kinds of reproduction in animals. It helps you to understand the chapter in a perfect way. They answer significant questions like what is a reproduction, and what are the different types of reproduction.
- Sexual reproduction
This topic of CBSE NCERT Class 8 Science Chapter 9- Reproduction in Animals describes sexual reproduction. In this type of reproduction, female and male reproductive organs produce female and male gametes, respectively. When these two different gametes fuse, a new offspring is formed. Here you will learn how both parents pass on their genetic information to their offspring. For example, reproduction in humans.
- Asexual reproduction
In this part of CBSE NCERT chapter 9, you will learn that asexual reproduction in animals is another type of reproduction where only one parent gets involved. No genetic information gets mixed. In Hydra, this type of reproduction usually happens.
Following are some different types of asexual reproduction
CBSE Class 8 Science Chapter 9 explains in detail about budding. It tells you that It is a type of asexual reproduction that occurs in different organisms such as Yeast and Hydra. This chapter explains this concept with the help of detailed illustrative diagrams to help you understand better.
This subtopic of NCERT CBSE Class 8 Science Chapter 9 describes that fission is an asexual reproduction where a one-celled organism divides into two cells. At first, the nucleus of the cell divides, then cell organelles divide and finally, the cytoplasm divides and makes two cell bodies. Fission can be of two types: binary fission and multiple fission. In Amoeba, you can find reproduction by way of binary fission.
This topic also explains that when one parent cell reproduces multiple daughter cells, multiple fission occurs. NCERT Solutions for Class 8 Science Chapter 9-Reproduction in Animals, explains this concept diagrammatically so that you can understand it better.
- Cell division
In this part of NCERT solutions, Class 6 Science Chapter 9- Reproduction in Animals, talks about cell division by reproduction. It states that life cannot generate without cell division. It also says that without cell division life cannot grow, regenerate or repair. Gamete formation is also not possible without cell division.
The cell divides in two ways:
- Mitosis: In this subtopic of NCERT Solutions for Class 8 Science Chapter 9-Reproduction in Animals, it explains that mitosis is when a single cell divides into two identical daughters. This section also elaborates about the steps of mitosis, namely interphase, prophase, metaphase, anaphase and telophase through a self-explanatory diagram.
- Meiosis: In CBSE NCERT Solutions for Class 8 Science, another type of cell division is meiosis, where one cell divides into four haploid cells. This has been explained in detail with the help of diagrams.
- Human sexual reproduction
This topic is an essential part of NCERT solutions Class 6 Science Chapter 9- Reproduction in Animals. Here we speak about human reproduction. Human reproduction has been divided into two main subtopics, i.e., male reproductive system and the female reproductive system.
- Male Reproduction
This topic of Class 6 Science Chapter 9, gives details about the male reproductive system. The male reproductive system includes testes, penis and sperm ducts. Sperms are the male gametes and produced in testes. With an illustrative diagram, this section describes the whole reproductive system. It teaches you that sperm is a microscopic cell, a body divided into head, middle piece and tail. This section explicitly elaborates about each part of the male reproductive organ in humans and also tells you about the functions of each part.
- Female reproduction
This part of the NCERT solutions class, 8 Science Chapter 9-Reproduction in Animals, explains the female reproductive system. It consists of vagina, cervix, ovary, endometrium, uterus, fimbriae, and fallopian tubes. The ovary produces Ovum is the female gamete, much larger than the male gamete or sperm. This section also speaks about ovary that secretes Oestrogen or Estrogen hormone that helps in the development of female sex organs, secondary sexual characteristics in the female. This hormone also controls the menstrual cycle in the female.
Fertilization is a vital process that creates new life. NCERT Solutions for Class 8 Science Chapter 9-Reproduction in Animals helps you understand the process of fertilization in humans through a detailed diagram. It explains that when male gamete or sperm comes in contact with female gamete or ovum, both fuse and form zygote. This zygote is carried to the uterus and forms the embryo. This process occurs in fallopian tubes. Both male and female gametes contain a single set of haploid chromosomes, after fusing, it maintains the chromosome numbers in the new life.
