cell transport

Question 1

osmolarity

Answer 1

total concentration of solute particles in a SOLUTION (Osm/L)

Question 2

molarity formula

Answer 2

1 mole of NaCl/ 1 liter of solution = 1M

Question 3

tonicity

Answer 3

measure of osmotic gradient between two solutions separated by semipermeable membrane.

Question 4

hypotonic

Answer 4

lower concentration of solutes

Question 5

hypertonic

Answer 5

high concentration of solutes

Question 6

isotonic

Answer 6

equal concentration from cell and solution

Question 7

if the solution tonicity is hypotonic what is the cell shape?

Answer 7

The cell will swell
- the solution will move into the cell

Question 8

if the solution tonicity is hypertonic what is the cell shape?

Answer 8

• cell shape will shrink
  -there is more water outside

Question 9

if the solution tonicity is isotonic what is the cell shape?

Answer 9

the cell shape doesn’t change

Question 10

How does solute particle size affect diffusion?

Answer 10

-If the particle is small, it will diffuse faster than larger ones because of the lower resistance and higher energy they have compared to larger particles.

Question 11

what’s the formula for percentage change?

Answer 11

final weight-initial weight/ initial weight x100
