ESSENTIAL QUESTION:
WHAT ARE THE
STRUCTURES AND
FUNCTIONS OF PLANT
AND ANIMAL CELLS?
DIFFERENCES BETWEEN PLANT &
ANIMAL CELLS
Shape:
- Plant: rectangular
- Animal: circular
Cell Wall:
- Plant: rigid Cell Wall
that surrounds the cell
- Animal: do not have
Chloroplasts:
- Plant: converts sunlight
into food
- Animal: do not have
Vacuoles:
- Plant: have 1 large Vacuole
- Animal: have several
smaller Vacuoles

CELLS FUNCTIONS
•  Cytoplasm
Thick, jelly-like substance
Holds cell organelles in place inside
the cell
Helps support & protect the cell’s
organelles
CELLS FUNCTIONS
•  Cell Membrane
Function is to regulate the transfer of
material in & out of the cell
Maintains homeostasis
CELLS FUNCTIONS
•  Nucleus
Round, double-walled structure
Found in the center of plant/animal cells
Function is to contain genetic material
Controls cell’s activity
CELLS FUNCTIONS
•  Mitochondria
Function is to produce energy for
cellular functions
Breaks down sugar (glucose) to
produce energy
Known as the Power House of the cell
CELLS FUNCTIONS
•  Vacuoles
Round in shape
Bigger in plants, smaller & several in
animals
Function is to store water, waste, &
nutrients for the cell
In Plants stores mostly water
CELLS FUNCTIONS
•  Chloroplasts
Oval discs with green chlorophyll
Found in plant cells
Function is to use the energy from the
sun (photosynthesis) to make food
(glucose) & oxygen
CELLS FUNCTIONS
•  Cell Wall
Rigid outer layer of plant cells
Function is to help maintain its shape
under the changing water pressure
Supports & Protects
