4. Why do living organisms need to reproduce?
Each organism can live for a certain period of time. Hence, organisms need to reproduce to continue the survival of their kind. The only way by which a species can continue to survive is by reproduction. It is a necessary process by which any living being maintains the continuity of its genes. An organism’s characteristics are heavily dependent on how it brings its offspring to the world. It is compulsory for Biology students to learn the reproduction process in order to understand how life sustains.
5. What do you understand by reproduction according to NCERT Solutions for Chapter 1 of Class 12 Biology?
Reproduction is a biological process where the living organism gives birth to the offspring, which has the similarity of the living organism giving birth. This offspring grows, gets mature and further gives birth to its own offspring. Reproduction is the continuous cycle of birth, growth and death and helps in the continuity of the species from generation to generation.
6. Name the important concepts discussed in NCERT Solutions for Class 12 Biology Chapter 1.
The topics in Class 12 Chapter 1 Reproduction are;
Topic 1 Characteristic features of all organisms for continuation of species.
Topic 2 Modes of Reproduction – asexual and sexual reproduction.
Topic 3 Asexual reproduction.
Topic 4 Binary fission.
Topic 5 Sporulation.
Topic 6 Budding.
Topic 7 Gemmule formation.
Topic 8 Fragmentation.
Topic 9 Vegetative propagation in plants.
These topics have to be studied and understood correctly to ace the exam.
7. Sexual reproduction is the better way of reproduction. Give reasons?
Sexual reproduction is considered a better way of reproduction because the DNA of the two individuals is combined and forms a new variant. This is formed by the fusion of male and female gametes. Hence, the offspring produced can sustain the environmental changes. One more important reason is that the survival of the species is more significant compared to the other methods of reproduction.
8. What do you understand about clones?
The offspring formed by the asexual reproduction where only a single parent is involved is known as clones. This is a word used to describe genetically identical groups. This can be mainly seen in prokaryotic organisms and some eukaryotic single-celled and multicelled organisms. A detailed explanation of the chapter can be found in Vedantu’s NCERT Solution in a very organized way helping the students to have a better understanding.
9. What kind of reproduction is involved in the eyes of potato and leaf buds of Bryophyllum?
The process of reproduction in both cases is vegetative reproduction, which is also asexual reproduction. The new plants are obtained from the vegetative parts of a plant. Like the eyes of a potato, the surface of the potato that looks like an eye when buried gives rise to a new plant. Similarly, the Bryophyllum plant has many buds in the edges and when the leaves break, the shoots grow into a tiny new plant when they come in contact with the moist soil.
