No individual is immortal then it is wondering that vast number of plant and animal species have existed on earth for several thousands of years. There must be some processes in living organisms that ensure this continuity. This process is called

Options

A. Growth
B. Development
C. Reproduction
D. Fertilisation

Answer

**Step-by-Step Solution:**

1. **Understanding Immortality in Organisms**:
- No individual organism is truly immortal, but some species can exist for thousands of years. This raises the question of how these species maintain their existence over time.

2. **Identifying the Process**:
- The key process that allows for the continuity of species is reproduction. Reproduction ensures that the genetic material is passed on to the next generation, allowing species to survive even if individual organisms die.

3. **Types of Reproduction**:
- There are two main types of reproduction: asexual and sexual. Asexual reproduction, such as binary fission in single-celled organisms like bacteria, allows for rapid population growth and the creation of genetically identical clones.

4. **Asexual Reproduction Example**:
- In binary fission, a single bacterium divides into two daughter cells. This process does not involve sexual reproduction or the fusion of gametes, which means that the offspring are clones of the parent.

5. **Conclusion**:
- Therefore, the process that ensures the continuity of life in organisms, allowing species to exist over long periods, is reproduction, particularly asexual reproduction in certain organisms.

**Final Answer**: The process that ensures the continuity of life in living organisms is called **reproduction**.
