The size of the cells of an organism has no relation with the size of its body. Do you agree? Give reason for your answer.

Explanation

**Step-by-Step Solution:**

1. **Understanding Cell Size and Body Size**: Begin by recognizing that cells are the basic structural and functional units of life. They perform all the necessary functions to sustain an organism.

2. **Independence of Cell Size**: It is important to note that the size of cells does not vary significantly between different organisms, regardless of their overall size. For example, the cells in a small organism like a rat are similar in size to those in a much larger organism like an elephant.

3. **Functional Consistency**: The functions that cells perform are consistent across different species. This means that even though an elephant is much larger than a rat, the cells in both animals carry out similar functions, such as respiration, digestion, and reproduction.
