Cell Organelles Whats a Cell Organelle Humans have

Cell Organelles

What’s a Cell Organelle? • Humans have organs that do specific, important jobs. • Cell Organelles are a lot like Human Organs.

Organ: Stomach Job: Break down food after you eat it.

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

Organ: Kidneys Job: 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 Organelles Cell 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 Apparatus Receive 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.
