Correct Option: A

The process of regeneration of new individual of the same kind is called as

  1. Metabolism

  2. Differentiation

  3. Reproduction

  4. None of the above

Show answer
Correct Option: C
Explanation:

Reproduction refers to the process by which new individual organisms (offspring) are produced from their parent.

Some animals like Planaria reproduce by regeneration. It is a type of asexual reproduction in which an organism is capable of regrowing certain body parts or the whole organism from different pieces.
So, the correct option is 'Reproduction'.

Man and dog reproduce by

  1. Laying eggs

  2. Hatching eggs

  3. Producing young ones

  4. Through their roots

Show answer
Correct Option: C
Explanation:
Man and dog are viviparous that means they give birth to young ones through sexual reproduction.
So, the correct answer is 'Producing young ones'.

The production of offsprings by sexual or asexual process is called as

botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

  1. Division

  2. Growth

  3. Reproduction

  4. All of the above

Show answer
Correct Option: C
Explanation:

Reproduction is the process by which organisms produce offspring that are similar to themselves.

  • Reproduction can be either sexual or asexual.
  • Asexual reproduction involves only a single organism while sexual reproduction involves gamete formation from two different sexes and their fusion.
  • So, the correct option is 'Reproduction'.

The process of production of closely resembled young one is called as

botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

  1. Reproduction

  2. Division

  3. Growth

  4. None of the above

Show answer
Correct Option: A
Explanation:
  • Cell Division results in two or more daughter cells.
  • Growth is the irreversible increase in the dry mass of an organism. It is brought about by an increase in cell size or number.
  • Reproduction results in production of closely resembling young ones.
  • So, the correct option is 'Reproduction'. 

The process of propagation of new individual from the existing one is called as

botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

  1. Fertilization

  2. Syngamy

  3. Reproduction

  4. Propagation

Show answer
Correct Option: C
Explanation:
  • Reproduction refers to the production or propogation of new individuals by an organism. 
  • Syngamy of fertilisation refers to the fusion of gametes which may or may not be similar.
  • So, the correct option is 'Reproduction'.

Production of the same type of organism is called as 

botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

  1. Reproduction

  2. Division

  3. Duplication

  4. None of the above

Show answer
Correct Option: A
Explanation:
  • 'Re' prefix is used to denote 'again'.
  • Hence, reproduction word itself means 'again production' of the same type of organisms.
  • So, the correct option is 'Reproduction'.

Reproduction is a

  1. Biological process

  2. Chemical process

  3. Physical process

  4. None of the above

Show answer
Correct Option: A
Explanation:
Reproduction is the biological process by which new individual organisms or offspring are produced from their parents. It has two forms i.e., sexual and asexual.
So, the correct answer is option A.

Which one of the following is correct?

biology how do organisms reproduce? different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

  1. Reproduction is linked to stability of population of a species.

  2. Reproduction is linked to instability of a population.

  3. Reproduction is linked to instability of a species.

  4. None of the above.

Show answer
Correct Option: A
Explanation:

During the process of reproduction, the DNA is passed from one generation to another. This replication takes place with little or no errors. There is consistency which leads to stability of reproduction. Also, reproduction helps in replacing aging population with new population and thus ensures the survival of the species. In the absence of reproduction, one particular species will disappear with time.
Thus, the correct answer is the option (A).
