Term
|
Definition
| A cell divides because as a cell grows, the surface area becomes too small to allow materials to get in and out of cells at the proper rate. |
|
|
Term
|
Definition
• Requires energy
1. Cell Membrane Pumps- Carrier proteins are also involved in active transport. When energy is required they are called “pumps” because they move substances against the concentration gradient
2. Movement in Vesicles: Some molecules are too large to get across a membrane even with the help of a carrier protein. Vesicles enable the cell to take in, or get rid of, large substances. |

Definition
| The cell membrane folds in and forms a small pouch. The pouch then pinches off from the cell membrane to become a vesicle inside the cell. |

|
Term
|
Definition
| A vesicle moves into the cell membrane, fuses with it, and then releases its contents to the outside of the cell. |
