What is a Eukaryotic Cell?
Eukaryotic cells are found in many places.
Can you name some examples of
Eukaryotic cells?
Parts of a Eukaryotic Cell
CELL WALL- A rigid structure that gives the support to a cell.
It is the outermost part of a cell.
Plants have a cell wall made out of cellulose to help plants stand upright.

CELL MEMBRANE-
A protective barrier that encloses a cell.
It separates the cell contents from the outside.
ALL CELLS HAVE A
MEMBRANE!
It’s made up of lipids and proteins.
Parts of a Eukaryotic Cell
CYTOPLASM- A liquid web of proteins.
It helps keep cell membranes from collapsing.
It also helps cells move.
Suspends organelles
Parts of a Eukaryotic Cell
NUCLEUS- A large organelle that contains the cell’s
DNA (genetic material).
The nucleolus is a dark area inside the cell and makes ribosomes.
Parts of a Eukaryotic Cell
Ribosomes- The smallest of all organelles. Some are free floating and others are attached to membranes.
They make proteins
Proteins are made up of amino acids
ALL cells have ribosomes
Parts of a Eukaryotic Cell
ENDOPLASMIC
RETICULUM- (ER) A system of folded membranes in which proteins, lipids, and other materials are made.
There is Rough ER and Smooth ER
Parts of a Eukaryotic Cell
Rough ER is found near the nucleus
Ribosomes are found on the Rough ER and make proteins that are taken all over the cell.
The Smooth ER lacks ribosomes. It makes lipids and breaks down toxins.

MITOCHONDRIA-
The main power source in the cell.
It breaks down sugar to produce energy.
It stores energy as
ATP.
Most Eukaryotic cells have mitochondria

CHLOROPLAST-
Organelle found in plant and algae cells in which photosynthesis takes place to make food.
Photosynthesis is the process by which plants use sunlight,
Carbon Dioxide, and water to make food.

GOLGI APPARATUS-
The organelle that packages and distributes proteins
It looks like the Smooth
ER
This membrane pinches off to form small bubbles that transport contents to other places in the cell
Parts of a Eukaryotic Cell
VESICLE- A small sac that surrounds material to be moved into or out of a cell.
ALL Eukaryotic Cells have Vesicles
Parts of a Eukaryotic Cell
LYSOSOMES-
Organelles that contain digestive enzymes
They destroy wornout or damaged organelles, get rid of waste, and protect the cell from foreign invaders.
Parts of a Eukaryotic Cell
Vacuoles- A Large
Vesicle that stores digestive enzymes and aid in digestion within the cell.
Some vacuoles store plant cells water and other liquids
ONLY FOUND IN
PLANTS!
