Ch10 movement through membranes Flashcards
1
Q
diffusion
A
is the movement of molecules from areas of high concentraion to areas of lower concentration
2
Q
osmosis
A
the movement of water from an area of high concentration of water to an area of lower concentration across a semi-permeable membrane
3
Q
osmoregulation
A
the control of water and salt levels in the cell or the organism
4
Q
turgor pressure
A
the force of the cell contents against the cell wall in plant cells
5
Q
turgid cell
A
a plant cell in which the contents of the cell are pushing against the cell wall due to turgor pressure
6
Q
plasmolysis
A
the loss of turgor pressure in a plant cell due to loss of water from the cytoplasm
7
Q
active transport
A
the absorption of molecules into cells against the concentration gradient, using energy
