transport if the CO2 moves into the cell?

3. Is this diffusion, osmosis, or active
transport if food moves into the cell?
5. 4. If diffusion occurs, which direction
will the oxygen move?
59% Oxygen
43% Oxygen
6. Salt Water Solution
5. If osmosis occurs, will water move
into this cell or out of this cell?
7. Passive Transport:
• In diffusion, substances move
from areas of HIGHER
concentration to areas of
LOWER concentration.
8. Passive Transport:
• If the substance that is moving
from high concentration to low
concentration is water, then we
call it osmosis.
9. Active Transport:
• If diffusion just won’t work (maybe
because the substance needs to
come in but diffusion would be
forcing it out), then the cell has to
use energy to make the substance
go from low to high.

It’s moving from

The water is moving

This food is moving
into the cell, that’s from
low to high – that’s not
diffusion!

High

Low

It’s just a bit higher
outside, but the oxygen
would still try to
balance, so it needs to…
Move into
the cell
14. Salt Water Solution
5. If osmosis occurs, will water move
into this cell or out of this cell?
Since this cell is in salt
water, that means that
there is more water
inside the cell than
outside….
The water would move
out of this cell and
it would
appear to shrink.
