Most cells are microscopic because at this small size, __________.
A
free-living unicellular organisms are difficult for predatory organisms to detect and capture
B
many more cells can be packed into an organ while maintaining its compact size
C
smaller cells require fewer nutrients and increase the probability of survival
D
the amount of vulnerable plasma membrane is minimized relative to that of a larger cell with more cytoplasm
E
the ratio of surface area to cell volume is maximized
Verified step by step guidance1
Understand that the problem is asking why most cells are microscopic in size.
Recognize that the size of a cell affects its surface area to volume ratio, which is crucial for efficient nutrient uptake and waste removal.
Recall that as a cell grows, its volume increases faster than its surface area, leading to a decreased surface area to volume ratio.
A high surface area to volume ratio is beneficial because it allows for more efficient exchange of materials between the cell and its environment.
Conclude that cells remain small to maximize their surface area to volume ratio, which is essential for maintaining cellular functions and survival.
