Identify the correct statement from the following .

Options

A. Prokaryotic cells has only one ribosome
B. Vacuoles are not present in all prokaryotic cells.
C. Cell wall is present in all prokaryotic cells.
D. Size of a typical eukaryotic cell is

Answer

To identify the correct statement from the options provided, we will analyze each statement one by one:

1. **Statement 1**: "Prokaryotic cell has only one ribosome."
- This statement is incorrect. Prokaryotic cells, such as bacteria, contain multiple ribosomes. They are involved in protein synthesis and can have many ribosomes attached to a single mRNA strand.

2. **Statement 2**: "Vacuoles are not present in all prokaryotic cells."
- This statement is correct. While some prokaryotic cells may contain vacuoles, they are not universally present in all prokaryotic cells. Vacuoles primarily function in storage and osmoregulation.

3. **Statement 3**: "Cell wall is present in all prokaryotic cells."
- This statement is incorrect. While many prokaryotic cells have a cell wall, there are exceptions, such as mycoplasma, which lack a cell wall.

4. **Statement 4**: "The size of the typical eukaryotic cell is."
- This statement is incomplete. It does not provide a specific size range, which is necessary for it to be considered correct. Typically, the size of a eukaryotic cell ranges from 10 to 100 micrometers.

After analyzing all the statements, we conclude that the correct statement is **Statement 2**: "Vacuoles are not present in all prokaryotic cells."
