There is no natural death in single celled organisms like Amoeba and bacteria because

Options

A. they cannot reproduce sexually
B. they reproduce by binary fission
C. parental body is distributed among the offspring
D. they are microscopic

Answer

**Step-by-Step Solution:**

1. **Understanding Single-Celled Organisms**: Single-celled organisms like Amoeba and bacteria reproduce through a process called cell division. Unlike multicellular organisms, they do not have a complex life cycle that includes aging and natural death.

2. **Reproduction Mechanism**: These organisms primarily reproduce asexually through binary fission. In binary fission, the parent cell divides into two equal halves, each of which grows into a new individual.

3. **Distribution of Parental Body**: When a single-celled organism divides, the parental body is effectively distributed among the offspring. This means that the original cell does not die; instead, it continues to exist in the form of two new cells.

4. **Absence of Natural Death**: Since the process of reproduction involves the division of the parent cell into offspring, there is no concept of natural death as seen in multicellular organisms. The parent cell's genetic material and cellular components are passed on to the new cells, allowing them to continue living and growing.

5. **Conclusion**: Therefore, the reason there is no natural death in single-celled organisms like Amoeba and bacteria is that the parental body is distributed among the offspring during reproduction, and the original cell does not die but continues to exist in the new cells.

**Final Answer**: There is no natural death in single-celled organisms like Amoeba and bacteria because the parental body is distributed among the offspring during reproduction.
