Important Topics for Lakhmir Singh and Manjit Kaur Solutions for Class 8 Science Chapter 9
The important topics which are described in Lakhmir Singh Solutions for Chapter 9 – Reproduction in Animals are listed below:
What is Reproduction?
Reproduction is the method of producing characters of the same kind. Most of the organisms reproduce by pairing off that rises the hereditary variability of the organism. The males and females have distinct reproductive organs identified as gonads. These gonads generate gametes that fuse together to form a single cell termed the zygote.
Modes of Reproduction
Depending on the number of parents included, there are various modes of reproduction. In animals, reproduction is of two types including Sexual Reproduction and Asexual Reproduction.
Sexual Reproduction in Animals
The method in which the male and female gametes fuse together to produce a new character is called sexual reproduction. Let us have a detailed account of the human reproductive organs and their role in reproduction.
The male reproductive organs consist of a pair of sperm ducts, testes, and a penis. The sperms are generated by the testes. The sperms are very small in size with a middle piece, a head, and a tail.
The female reproductive organs consist of a pair of oviducts, ovaries, and uterus. The eggs are formed by the ovaries. The growth of the baby takes place in the uterus. A mature egg is unconfined into the oviduct every month.
The zygote splits frequently to form a ball of cells. This ball of cells is well-known as the embryo. These cells separate into respective tissues and organs. The embryo gets inserted into the wall of the uterus. This process is called implantation. When all the body parts of the embryo start being noticeable, it is named a foetus. The child is completely developed after nine months.
Asexual Reproduction in Animals
Asexual Reproduction is the process in which a new character is produced by the association of a single parent with or without the participation of the gamete formation. The entities produced are genetically and morphologically alike. It generally takes place in unicellular organisms. The cells are split by mitotic division and no reproduction takes place. The separation occurs very quickly.
Types of Asexual Reproduction
The different types of Asexual Reproduction available are Regeneration, Binary Fission, Fragmentation, Budding, and Parthenogenesis.
