Download Plant Cell

Hypo-
Describe: There is a higher
concentration inside the cell
than outside. Water moves
into the cell to equal out
concentration
Animal Cell (RBC and Cell in
Beaker): Cells swell and burst
due to water moving in.
Plant Cell: Cells remain in a
normal “turgid” state but the
vacuoles are swelled and full.
Iso-
Describe: The inside of the cell
and outside has an equal
proportion of concentration.
Water continually flows in and
out to keep concentration
balanced.
Animal (RBC and Cell in Beaker):
cell is in normal condition as
homeostasis has been reached.
Plant Cell: Cell is in normal
condition. Vacuole is full but not
overly.
Hyper-
Describe: Concentration inside is
less than outside of the cell.
Water moves out of the cell to
try to even out the
concentration.
Animal(RBC and Cell in Beaker):
Cell has lost so much water that
it is shriveled.
Plant Cell: vacuole has lost water
and cytoplasm shrinks away
from the cell wall causing a loss
of turgidity. (plant wilts).
Exocytosis:
Part of the cell membrane surrounds materials in a vesicle and
carries them out of the cell to be released outside.
Used for:
-Molecules that are too large to move through the cell membrane
-Removing waste and worn out organelles
-Requires the use of ATP energy
-Active Transport
Endocytosis:
Part of the cell membrane surrounds materials in a vesicle and
carries them into the cell to be released inside.
Used for:
- Molecules that are too large to move through the cell membrane
- Engulfing food
- Requires the use of ATP energy
- Active Transport
Passive Transport
Passive Transport: Diffusion of molecules
across the cell membrane WITHOUT the
use of ATP energy
Used for: -Movement of molecules from
high concentration to low concentration
WITH the concentration gradientContinues until concentrations reach
equilibriumExample: Carbon Dioxide, Water, Oxygen
Movement of water molecules from high
to low
-Osmosis: Movement of water
molecules from high to low
concentration with the gradient.
Continues until concentrations
reach equilibrium/homeostasis.
Does not require energy = passive
transport
Active Transport
Active Transport: Movement of
molecules across the cell membrane
using ATP ENERGY
Used for:-Movement of molecules
from low concentration to high
concentration against the
concentration gradient.
Example: Sodium and PotassiumMolecules that are too large to move
through the cell membrane easily.
Example: Glucose and Starch
Transport Protein: Protein
embedded in the cell membrane
responsible for “picking up”
molecules from the outside or
inside of the cell and carrying them
across the cell membrane
Used for:-Molecules that are too
large to move through the cell
membrane
-Requires ATP energy = ACTIVE
TRANSPORT
