Answer and Explanation:
Size of the cell=diameter of field in цm/number of cells across the field
Example:
A student observed a row of 16 epidermal cells in a microscopic field that was 800цm in diameter. Calculate the average length of each cell.
Answer:
size of the cell=8000цm/16
= 500цm.

Answer:
The correct answer is <em>c.pinocytosis – liquids secreted from the cell </em>
