Question
Red Blood cells can be seen with the naked eye
Correct Answer
Option B is the correct answer.
Detailed Explanation
This statement is false. Red blood cells are microscopic. A single red blood cell is about 6-8 micrometers in diameter. The human eye's resolution limit is around 100 micrometers, so individual red blood cells are far too small to be seen without the aid of a microscope.
Hint
Think about the size of a cell compared to the point of a needle.
