When offspring is produced by single parent or without the 
involvement of gamete formation, the reproduction 
is asexual.

FAQs on Flashcards: Reproduction in Organisms (Old NCERT) - Flashcards for CUET UG Preparation

1. What is reproduction in organisms?
Ans. Reproduction in organisms is the biological process by which new individuals of the same species are produced, either sexually or asexually. It is a fundamental characteristic of all living organisms and plays a vital role in the survival and continuation of species.
2. What are the types of reproduction in organisms?
Ans. There are two main types of reproduction in organisms: sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of gametes (sperm and egg) from two parents, resulting in offspring with a combination of genetic traits. Asexual reproduction, on the other hand, does not involve the fusion of gametes and produces offspring that are genetically identical to the parent.
3. How does sexual reproduction occur in organisms?
Ans. Sexual reproduction in organisms involves the production of specialized cells called gametes, which are haploid (containing half the number of chromosomes) and have genetic material from both parents. These gametes, namely sperm and egg, unite during fertilization to form a zygote, which develops into a new individual. This process introduces genetic variation and allows for the exchange of genetic traits.
4. What are the advantages of sexual reproduction in organisms?
Ans. Sexual reproduction offers several advantages to organisms. Firstly, it promotes genetic diversity within a population, which enhances the chances of survival in changing environments. It also allows for the repair of damaged DNA through recombination. Additionally, sexual reproduction facilitates the elimination of harmful mutations and the evolution of new traits, leading to the adaptation and evolution of species over time.
5. What are the examples of asexual reproduction in organisms?
Ans. Asexual reproduction in organisms can take various forms. Some common examples include binary fission, where an organism divides into two identical individuals (e.g., bacteria); budding, where a new individual grows out of the parent's body (e.g., yeast); regeneration, where a complete organism regrows from a body part (e.g., starfish); and vegetative propagation, where new individuals arise from plant structures (e.g., runners in strawberry plants).
