Question 1

Conc. of solute outside cell = conc. inside cell .

Answer 1

no
change in size

Question 2

Conc. of solute outside cell > conc. inside cell →

Answer 2

cellshrinks
(Plasmolysis)

Question 3

Conc. of solute outside cell < conc. inside cell →

Answer 3

cell swells(Turgid)

Question 4

In animals:
Increasing solute concentration inside of cell cancause cell to

Answer 4

cell to
explode as a result of it having too muchwater, crenation.

Question 5

In plants:
Increasing or Decreasing solute concentration inside of cell causescell to

Answer 5

In plants:

Increasing solute concentration inside of cell causescell to
become turgid, vacuole fi lls up.

Decreasing solute concentration inside of cell causescell to
become fl accid, losing water and vacuole getssmaller. Cell body
shrinks, pulling away from cell wall

Question 6

Active Transport

Answer 6

Active Transport
Movement of particles through a cell membrane, from aregion of
lower concentration to a region of higherconcentration against a
concentration gradient, usingenergy released during respiration
Active transport is needed when an organism wants tooptimize the
amount of nutrients it can take up - ionuptake by root hairs and
uptake of glucose by epithelialcells of villi.

Question 7

Why r animal cells harmed by water and turgidity unlike plant cells

Answer 7

Plant cells have a cell wall
