Plant and Animal Cell
Organelles and Functions
LETS LEARN
ABOUT CELLS!
Animal Cell Organelles and Function
Nucleus:
Function: The control center of the cell which

holds the cell’s DNA.


Nickname: “The Brain of the Cell”
Parts:
1.
2.
Nuclear Membrane: A thin covering that
surrounds the nucleus allowing materials to
move in and out of the nucleus.
Nucleolus: Appears as a dark spot in the
nucleus; helps make proteins.

Ribosomes


Function: Organelles in the cell that make
proteins.
Found in all cells on the ER
Chromosomes: Organelles that carry genetic
information for each cell.

Endoplasmic Reticulum (ER)
Function: The internal delivery
(transportation) system of the cell.

Nickname: “Roads of the cell”
Cytoplasm: The jelly-like material between
the cell membrane and the nuclear
membrane which holds organelles in the
cell.

Endoplasmic Reticulum

2 Types of Endoplasmic Reticulum:
1.
Rough ER:


2.
Rough appearance because it has ribosome's on
it.
Function: Helps to make proteins, with it’s
ribosome's.
Smooth ER:


NO ribosome's
Function: The smooth ER makes fats or lipids.

Golgi Bodies:
Function: To package, modify, and
transport materials to locations inside
and/or outside the cell.

Nickname: The shippers (UPS of the cell)

Appearance: Looks like a stack of
pancakes
Vacuoles: A sac filled with liquid and
nutrients, used for storage. Plants have
one large vacuole and animals have
several small vacuoles.

Mitochondria


Function: The mitochondria make energy
for the cell.
Nickname: “The Powerhouse of the Cell”
you can remember this by remembering
“the MIGHTY MITOCHONDRIA!”

The mitochondria break down food to
make ATP.
 ATP: is the major fuel for all cell
activities that require energy.

Now let’s talk about structures only
found in PLANT Cells!!
Plant Cell Organelles and Function
Vacuoles: Each plant cell only has 1!

Function: The vacuole stores water and
nutrients.

This is what makes lettuce crisp.

When there is no water, the plant
wilts.

Chloroplasts


Function: Chloroplasts trap energy from
the sun to produce food for the plant cell.
Chloroplasts are green in color because
of chlorophyll, which is a green pigment
that has its own function in a plant cell.

Chlorophyll


Chlorophyll works much like a solar panel,
absorbing light energy, which is then stored as
food energy. Chlorophyll uses the suns light
energy to change carbon dioxide and water into
glucose and oxygen. This process is called
photosynthesis.
Photosynthesis
Photosynthesis is the process of using light
energy to combine carbon dioxide and water to
produce glucose which plants use as food.
Plant Cell Organelles and Function
Cell Wall


Function: The plant cell wall provides
support and protection to the cell
membrane much like a brick wall protects
a house.
Found outside the cell membrane in plant
cells; the cell wall gives plant stems and
tree limbs their rigid structure.
