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. Nuclear Membrane: A thin covering that surrounds the nucleus allowing materials to move in and out of the nucleus.
2. Nucleolus: Appears as a dark spot in the nucleus; helps make proteins.

Animal Cell Organelles and Function
Cell Membrane: The thin covering that surrounds the cell allowing materials to move in and out of the cell.
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: Rough appearance because it has ribosome's
on it. Function: Helps to make proteins, with it’s
ribosome's.
2.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.

Plant Cell Organelles and Function
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.
PhotosynthesisPhotosynthesis 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.
