Eukaryotic Cells

Their Functions and Roles

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.

Parts of a Eukaryotic Cell

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!
