| diffusion | The movement of a substance from an area of high concentration to an area of low consentration (no energy - needed). |
| osmosis | Diffusion of <b> water </b> across the cell membrane. |
| active transport | Is used for substances that can not cross the cell membrane without energy. The large particles in the cell membrane (made of protein) help move the substances across the membrane. |
| photosynthesis | PLANTS - "putting together with light" - plants use the energy in sunlight to make glucose and carbon dioxide |
| respiration | ANIMALS - process where animals release the energy stored in glucose |
| fermentatoin | When cells do not have enough OXYGEN to carry out respiration glucose is broken down to form a carbon dioxide and an acid. |
| Two types of passive transport | Difusion & Osmosis = both processes require NO enery |
| three types of energy producing processes | Photosynthesis , Respiration , & Fermentation |
| In what 2 processes is glucose broken down to form carbon dioxide and an acid. | Respiration & Photosynthesis |
| Name 2 things that move in our body through passive transport. | Oxygen and Water |
| The process by which a cell nucleus devides into two identical nuclei | mitosis |
| There are ____ phases in mitosis | 5 |
| chromosomes | These are threadlike strands located in the cell's nucleus, they control the cell's activity. |
| impermeable | If substances do not pass through the membrane (the cell wall is like a barrier) the cell wall is considered ... |
| selectivley permeable | If a membrane is permeable to some materials but impermeable to others, it is described as .... |
| permeable | When substances are able to pass freely into or out of a cell's membrane, the membrane is said to be. |
