NCERT Solutions for Class 12 Biology Chapter 1 - Reproduction in Organism
The process of reproduction assists one to give birth to their offspring. It is a natural procedure which all living beings must follow for continuity of life on earth. Also, it can be taken as an entire life cycle of an organism, starting from birth, development and finally, death.
NCERT Solutions Biology Class 12, chapter 1 will make learners comprehend the different reproduction methods of organisms. High emphasis is given on this subjective topic such that you can have a clear understanding of the same, and also know how to write the solutions.
NCERT Class 12 Biology Chapter discusses in detail the process of reproduction in organisms. It explains the types of reproduction in living organisms, i.e., sexual and asexual reproduction. Various diagrams and illustrations are provided to help the students understand the difference between the sexual and asexual modes of reproduction.
Some of the important topics discussed in this chapter are mentioned in the table below:
Importance of Class 12 Biology Chapter 1 Topics
NCERT Solutions for Class 12 Biology Chapter 1 holds an important weightage in Class 12 Board exam. The topics covered are important to clear your concepts on different modes of reproduction in organisms. It gives a clear picture of the differences between sexual and asexual reproduction. In comparison to asexual reproduction, the sexual mode of reproduction is a more complex and slow process. The majority of higher animals reproduce nearly through the mode of sexual reproduction. Asexual reproduction is common in organisms such as fungus, algae, and some invertebrate organisms. Asexual reproduction produces identical offspring, which are referred to as clones. This chapter is also important to understand the process of mitosis, meiosis and post-fertilization events.
FAQs on Class 12 NCERT Solutions for Biology Chapter 1
1. What will a Student get to Learn in the Chapter of Reproduction in Organism?
This chapter of CBSE 12 comprises the topics of asexual reproduction, reproduction necessity, budding, binary fusion, fragmentation, sexual reproduction, vegetation propagation, sexual reproduction in plants and advantages of sexual and asexual reproduction.
By studying this chapter, students will get to know the processes of reproduction in detail. Moreover, this unit focuses on female and male reproductive systems, plant reproduction, contraceptive methods and fertilisation. Reproduction is essential for the progression of species on the planet. If organisms stop reproducing, there will be a discontinuity of life.
2. How is DNA Important in Reproduction? Is it Related to Proteins?
DNA is exceptionally vital for all living creatures on earth, even in plants. They are essential for coding for proteins, inheritance and acts as a guide of genetic instruction for life and related processes. DNA stores the information for each cell’s or a living being’s development, reproduction and finally death.
DNA holds the codes for proteins, but the real protein is different from the codes available on DNA. The fundamental steps included are transcription, translation, and at last, modification and folding.
3. Why is an Offspring Born from Sexual Reproduction Likely to Survive More Than Asexual Reproduction?
The mode of sexual reproduction necessitates female and male gamete fusion. During the zygote formation process, exchange of traits and genes takes place between the gametes. Similarly, during the process of chromosome segregation and crossing over, chances of elimination of non-identical characteristics are much higher. Therefore, the offspring born does not resemble its parents and hence more chances of survival. However, if the mother parent is suffering from an acute disease like AIDS, etc., the child may not survive for long.

5. Define clones according to Chapter 1 of Class 12 Biology?
During an asexual reproduction there is only one parent involved and no fusion takes place between the male and the female gamete. The offspring produced by this kind of reproduction are identical genetically and also morphologically to the parent. The offspring that do not show any variations and are vulnerable to the environment are called clones. The chapter is well defined systematically in Vedantu which becomes easy for the students.

7. List out the important concepts discussed in NCERT Solutions for Chapter 1 of Class 12 Biology.
The important concepts discussed in NCERT Solutions Class 12 Biology are Reproduction, Sexual Reproduction In Flowering Plants, Male And Female Reproductive Systems, Reproductive Health, Mendel’s Laws Of Inheritance, Genetics And Evolution, Common Diseases In Humans, Role Of Animal Husbandry, Microbes, Biotechnology, Biotechnological Applications In Agriculture, Hibernation, Nutrient Cycle, Biodiversity And Conservation, Air Pollution And Its Control, Water Pollution And Its Control.
8. What is Reproduction according to Chapter 1 of Class 12 Biology?
Reproduction is the process of living organisms giving birth to their young ones similar to them. This is a continuing process from one generation to another. If there is no reproduction, then the species will not live for a long time or may even become extinct. The world would have ended without this process.
