Hey there!
Your question states: <span> Explain why cells are so small, considering the relationship between surface area and volume for objects of different sizes but similar shapes.
Cell's are small because the size of the other surface area's and also there volume would obviously be bigger than the cell it self. So, they are basically bigger based on that it</span><span> is the most efficient at their </span><span>size. Cell's can not be big and there on some one's hat, that would be very weird. This would be why cell's are the size that they are.</span>

Answer: The Earth
This was believed to be true for hundreds of years....
Option1) a cell membrane.
Option2) kinetic energy.
If none of these options are right. Can I please have the right answer, I would love to know.
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular.Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells.
Difference Between Plant And Animal Cells 1 Chloroplast. Like animal cells plant cells have mitochondria. 2 Cell Wall. Animal cells do not contain a cell wall while plant cells and fungi cells do. 3 Vacuole. Vacuoles are very large membrane-bound sacs within plant cells.
