... have a copy of the DNA from the mother cell, so preparing to divide means the mother cell has to copy its DNA. Cells divide for various reasons: 1. growth of organism 2. healing or repair of tissues 3. to increase the efficiency of cells grown too large 4. reproduction in single-celled living things ...

... Cells are microscopic, they are visible only with light microscopes. Most of their size ranges from 1-100 µm. Cells are small, because they have to be able to carry materials from one side of the cell to the next in a short period of time. Cells must have a large enough surface area to be able to ta ...

The Cell Membrane
... 1. The cell is an open system with both matter and energy flowing in and out. The three roles of the cell membrane is to: a. Maintain equilibrium (balance) inside the cell b. Transport materials in and out of the cell c. Recognize foreign cells and communicate with other cells 2. The cell membrane ...
