Question
Majority of cells cannot be seen directly with our naked eyes because: a. organisms are generally unicellular b. cells are grouped into tissues c. cells are microscopic d. cells are present only inside the body
Correct Answer
Option C is the correct answer.
Detailed Explanation
The primary reason we cannot see most cells with the naked eye is their extremely small size. Most cells are microscopic, meaning they are below the resolution limit of the human eye. The resolution of the human eye is about 0.1 mm, and many cells are much smaller than that.
Hint
It's a simple matter of scale – they are just too tiny.
