Reproduction in Animals Class 8 Science (Chapter 9) in One Shot | BYJU'S - Class 8
BYJU'S - Class 6, 7 & 8・2 minutes read
Ankita introduces the topic of reproduction, discussing the importance of reproduction for species continuation, including asexual and sexual reproduction with examples like binary fission and cloning. The text also covers the processes of fertilization, zygote formation, and the role of gametes in genetic inheritance.
Insights
- Asexual reproduction involves only one parent and creates identical offspring, while sexual reproduction involves two parents, combining genetic material through gametes to create unique offspring.
- Cloning, exemplified by Dolly the sheep, involves transferring genetic material from one cell to another, resulting in an identical copy of the original organism, showcasing the potential for human intervention in reproduction processes.

Recent questions
What is reproduction?
Reproduction involves producing offspring similar to the parent organism. It is essential for the continuation of species and has led to the Earth's population reaching 8 billion.
How does asexual reproduction occur in amoeba?
Asexual reproduction in amoeba occurs through binary fission, where the cell splits into two identical daughter cells. This process results in the production of offspring that are genetically identical to the parent organism.
What is cloning?
Cloning is a process that involves creating exact copies of an organism by combining genetic material from different sources. Dolly the sheep was the first cloned sheep, created through a unique process that included taking a cell from one sheep and the nucleus from another sheep's egg.
What is the role of gametes in sexual reproduction?
Gametes are specialized reproductive cells involved in sexual reproduction. In males, sperm is the gamete, while in females, the ovum serves as the gamete. The fusion of these gametes during fertilization results in the formation of a zygote, which is the first cell of a new organism.
What is the function of the placenta during pregnancy?
The placenta is a vital organ that provides nutrition and waste removal between the mother and fetus during pregnancy. It plays a crucial role in supporting the developing baby by facilitating the exchange of nutrients and oxygen between the mother's and baby's bloodstreams.
