Cell Organelles

What’s a Cell Organelle?

• Humans have organs that do specific, important jobs.

• Cell Organelles are a lot like Human Organs.

Organ: StomachJob: Break down food after you eat it.

Organ: Heart• Job: Pump Blood (oxygen) through the body.

Organ: KidneysJob: Clean blood & remove waste from body (pee).

What are Cell Organelles?• Inside a human,

there are organs that do special jobs to keep the human alive.

• Inside a cell, there are organelles that do special jobs to keep the cell alive.

Cell OrganellesCell Organelle: a structure inside of a cell that does a special job to keep the cell alive.

Nucleus- Controls functions of the cell. - Holds genetic information.

Nucleus - City Hall• The nucleus is responsible for controlling

the rest of cell just like a city hall is where the city is governed from.

Chromosomes - Blueprint • The chromosomes are the DNA of a cell

which is like a blueprint for a building or structure.

Endoplasmic Reticulum - Roads

• The Endoplasmic Reticulum is like roads in a city, transporting proteins around the cell.

Ribosomes- Make proteins.

Ribosomes - Shops• Ribosomes are like small shops in a

city. The ribosomes produce proteins like shops produce important things for the city.

Golgi ApparatusReceive

proteins, package

them & send them to

other parts of the cell.

Golgi Apparatus – Post Office

The Golgi Appartus is like the post office, packaging & sending proteins to other

parts of the cell.

Mitochondria - Powerhouse- Makes energy that fuels the cell.

Mitochondria – Power plant• The mitochondria is like a power plant

because it produces energy like a power plant does for a city.

Cell Membrane• Regulates what goes in & out of a cell.

Cell Membrane - Fence• The Cell membrane is like a fence, because it

let’s some things in but keeps others out.

Cytoplasm - Grass • The cytoplasm is like the grass in a town,

all over and surrounding all the parts of a cell/city.

Vacuole

• Water & garbage storage.

* Plants have BIG

water vacuoles!

Vacuole – Garbage collector • The vacuole is like a garbage collector

getting rid of unwanted waste from the cell.

Chloroplast (Only Plants)• Site of photosynthesis.

Chloroplast – Solar Collector• The Chloroplast (only in plant cells)

convert sunlight into usable energy.

Cell Wall (Only Plants)• Gives structure to a plant cell.

Cell Wall – City Limits• The cell wall (a plant cell) of a cell is like

the city limits of a cell giving the cell/city its shape.
