| What three methods do materials move into and out of cells? |
|
Definition
| 1. Diffusion 2. Osmosis 3. Active Transport |
|
|
Term
|
Definition
| Molecules move for an area of higher concentration to lower concentration. |
|
|
Term
|
Definition
| Active transport is the movement of materials through a cell membrane using energy. Passive Transport in the opposite. |
|
|
Term
|
Definition
| Hypertonic - Cell shrivels up. Hypotonic - Cell grows bigger. Osmosis is a type of diffusion. Isotonic - Cell stays the same. |
|
|
Term
|
Definition
| This type of membrane only allows small molecules to pass through it through passive transport. Water molecules cross the membrane by osmosis. Other molecules like sugar use diffusion. Starch molecules are too big to pass through the membrane. Sugar molecules are small enough. |
|
|
Term
|
Definition
| Starch is made of simple chains of sugar particles held together by chemical bond. Amylase can break that bond. Starch molecules have to broken down so the sugars can pass through the membrane and be used for energy. |

|
Definition
| Mechanical Digestion increases surface area. More surface area allows enzymes to react more with food. More surface area decreases digestion time. |
|

Term
|
Definition
| Amylase is an enzyme in your saliva that breaks large starch molecules into smaller sugar molecules. |
