|
What are the principle of cell theory |
-all organisms are composed of cells -all cells come from pre existing cells -cells are the smallest structural and functional unit of organisms |
|
|
Why is cell size limited |
-Cells need a lage surface area of plasma membrane -surface area to volume ratio require cell to be small |
