Question

The statement ‘nothing lives forever, yet life continues’ illustrates the role of
A. Embryogenesis
B. Morphogenesis
C. Replication
D. Reproduction

Answer 1

Hint: The statement ‘nothing lives forever, yet life continues’ means that no organism lives forever, i.e. they die eventually but their species continue to survive on earth generation after generation.

Complete answer:
Let us look at each option individually.
A. Embryogenesis- when a male gamete fertilizes the female gamete a zygote is formed which is single celled. This single celled zygote develops and multiplies to form an embryo. The process by which embryo develops into a foetus is called embryogenesis.
B. Morphogenesis- It is the process by which an organism takes its shape by embryological processes of differentiation of cells, tissues, organs, and organ systems.
C. Replication- It is the process by which the DNA of prokaryotes and eukaryotes forms two copies which are identical to each other and the parent DNA. It is a semiconservative process, i.e. each new DNA contains a strand from the original DNA and a new strand.
D. Reproduction- Reproduction is the process by which organisms produce offspring of their own species. It ensures continuation of species on earth.
We know that no organism continues to live forever, but through the process of reproduction, organisms produce their offspring and ensure the survival of their species generation after generation.
Thus, we can say that the statement ‘nothing lives forever, yet life continues’ illustrates the role of reproduction.

Hence, the correct answer is option D.

Note:
Following are the features of replication-
1. It enables continuation of species.
2. It is of two basic types- asexual and sexual reproduction.
3. Sexual reproduction involves a single parent while in sexual reproduction there is the involvement of both the male and female parents.
4. In reproduction, replication of DNA takes place.
