Cell Key Defenitions

Question 1

Turgid

Answer 1

cell swells, cell membrane pushes out against cell wall in plants

Question 2

Flaccid

Answer 2

cell shrinks, cell membrane retracts, pulls away from cell wall in plants, because water has moved out of cell

Question 3

hypotonic

Answer 3

solution has lower solute concentration than the cell so water will enter the cell

Question 4

hypertonic

Answer 4

solution has higher solute concentration than the cell so water leaves by osmosis

Question 5

Isotonic

Answer 5

solute concentration of cell + solution are balanced

Question 6

Plasmolysis

Answer 6

cell has swollen + burst ( like red blood cells in pure water)

Question 7

organelles

Answer 7

specialised sub cellular structures found within living cells

Question 8

cells

Answer 8

basic structural unit of a living organism

Question 9

Question 10
