Which one of the following wavelengths is more effective for the photo morphogenetic phenomenon?

  1. $730$nm
  2. $680$nm
  3. $660$nm
  4. $560$nm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photomorphogenesis, particularly the phytochrome-mediated response, is most sensitive to red (660 nm) and far-red (730 nm) light. Far-red light (730 nm) is highly effective at converting Pfr back to Pr, influencing germination and growth.

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
Reveal answer Fill a bubble to check yourself
C Correct answer
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'.

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

  1. Division

  2. Growth

  3. Reproduction

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
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'.

A Correct answer
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'.

C Correct answer
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'.

Which one of the following is correct?

  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.
Reveal answer Fill a bubble to check yourself
A Correct answer
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).
