Complex organisms quite often have very highly specialized types of cells. Scientists theorize that there are many reasons for this. Which of the following is NOT one of the reasons? |
| | A) | Cells are able to change their size, shape, and functions to meet the needs of the organism. |
| | B) | Specialized cells are better able to meet the demands of a larger organism. |
| | C) | As an organism gets more complex, cells are naturally specialized based upon their primary function within the organism. |
| | D) | Many cells need to increase the amount of surface area that they have in order to increase the diffusion of materials across the membrane. They have done this by developing finger-like projections or folding of the cell membrane. |
