|
Plasma Membrane |
|
|
02. A ________________________ describes the difference across the membrane. |
Concentration Gradient |
|
|
03. Osmosis, diffusion, and facilitated diffusion are grouped into ___________________movements because they do not require cellular energy or potential energy (ATP). |
Passive Transport |
|
|
04. A/An ________________________ solution has the same concentration ofdissolved solutes in the surrounding solution as it does in the cytoplasm of the cell. |
Isoosmotic |
|
|
05. _________________________________ is the process of cells, such as whiteblood cells, engulfing large particulate matter. |
Phagocytosis |
|
|
06. _______________, ______________, and ________________ molecules diffuse across the plasma membrane vary easily. |
Oxygen; Carbon; Water |
|
|
07. _______________________________ is defined as the net movement of moleculesacross a selective permeable membrane from an area of low concentration to an areaof high concentration which requires potential energy or ATP. |
Active Transport |
|
|
