T2-osmosis/active transport Flashcards
Plasmolysis
Too much water is lost (osmosis)
Vacuole and cytoplasm shrink
Cell membrane pulls away from the cell wall
cells die quickly (unless osmotic balance restored)
Diffusion and Osmosis
Movement DOWN concentration gradient
From Higher to lower concentration
Cells hard and rigid
Correct amount of water in cells
Plant is well supported
turgid
osmosis
Diffusion of WATER
From a dilute to a concentrated solution
Through partially permeable membrane
Flaccid
Cells soft
Little pressure on cell walls
Plant wilts
Hypertonic
The concentration of solutes outside the cell is HIGHER than inside the cell
Shrivels - can no longer survive
The cell in a hypertonic solution
concentrated solution
The high concentration of sugar (the solute)
Low concentration of water (the solvent)
Hypotonic
The concentration of solutes outside the cell is LOWER than the inside of the cell
Dilute solution
The high concentration of water (the solvent)
Low concentration of sugar (the solute)
Concentrated solution
The high concentration of sugar (the solute)
Low concentration of water (the solvent)
Isotonic
Concentration is THE SAME inside and outside of the cell
The five kingdoms
Animals, Fungi, plants Protoctist and Prokaryotes
