Cellular Transport
Glencoe Chap 8.1
| Question | Answer |
|---|---|
| Active transport | cell moves materials across the cell membrane from area of lower concentration to higher concentration. Requires energy. |
| endocytosis | active transport (requires energy). Cell surrounds material with part of the plasma membrane and absorbs it into the cell. |
| exocytosis | Active transport (requires energy). process in which the cell removes materials from the cell. |
| facilitated diffusion | Passive transport ( does not require energy). Process that move materials through the plasma membrane via the transport proteins. |
| hypertonic solution | dissolved substances have a greater concentration outside the cell then inside the cell. Causes water to leave the cell and the cell to shrink |
| hypotonic solution | Concentration of dissolved substances is lower outside the cell than inside so water moves into the cell causing the cell to expand and possibly burst. |
| isotonic solution | concentration of dissolved substances outside the cell is equal to what is inside the cell. water molecules continue to diffuse through the membrane maintaining homeostasis in the cell. |
| osmosis | process of diffusion of water across the selectively permeable membrane of the cell. Direction of movement depends on the concentration of materials on either side of the cell membrane |
| passive transport | diffusion of particles across the cell membrane. No energy is used. |
