Term
|
Definition
| the movement of materials in and out of the cell without the use of energy. Things move with the concentration gradient from high to low. |
|
|
Term
|
Definition
| the movement of materials where the cell actually uses energy to pump it against the concentration gradient |
|

Term
|
Definition
| Proteins located on cell membranes that attach to certain molecules and move them into the cell |
|
|
Term
|
Definition
| where a cell engulfs a particle too large to pass through the memebrane and forms a vacuole around it. |
|
|
Term
|
Definition
| cells have to be small, because if they were too big diffusion could not occur |

Term
|
Definition
| first stage of mitosis where the copied chromatin pairs coil and are joined in the center by a centromere to form chromosomes |
|
|
Term
|
Definition
| second part of mitosis where the chromosomes move to the equator of the cell |
|
|
Term
|
Definition
| third stage where centromeres split and move toward poles |
|
|
Term
|
Definition
| The fourth phase where the cell splits to form two new cells and enters the interphase cycle |
|
|
Term
|
Definition
| when cells loose control of the usual cell cycle and uncontrolled dividing takes place |
|
|
Term
|
