Identify the statement which is true for cells.

Options

A. Cells can be easily seen with naked eyes.
B. Insect’s egg is not a cell.
C. A single cell can perform all the functions in a unicellular organism.
D. The size and shape of cells is uniform in multicellular organisms

Answer

To identify the true statement about cells, we can analyze each of the provided statements step by step:

1. **Statement 1: Cells can be easily seen with the naked eye.**
- This statement is **false**. Most cells are microscopic and cannot be seen without the aid of a microscope. Cells are generally too small to be observed without magnification.

2. **Statement 2: An insect egg is not a cell.**
- This statement is also **false**. An insect egg is indeed a single cell, known as a zygote, which is capable of developing into an organism.

3. **Statement 3: A single cell can perform all the functions in unicellular organisms.**
- This statement is **true**. Unicellular organisms, such as bacteria and amoebas, consist of only one cell, which carries out all the necessary functions for survival, including metabolism, reproduction, and response to the environment.

4. **Statement 4: The size and shape of the cells is uniform in multicellular organisms.**
- This statement is **false**. In multicellular organisms, cells can vary greatly in size and shape depending on their function. For example, nerve cells, muscle cells, and blood cells all have different structures and sizes.

**Conclusion:**
The true statement about cells is: "A single cell can perform all the functions in unicellular organisms."
