A cell is the smallest unit of life and makes up all living things. Different cells have specific roles like providing energy.

Organelles

Is a subcellular structure that has one or more specific jobs to perform in the cell.

Nucleolus

Surrounds the nucleus and stores the DNA

Nucleus Membrane

Surrounds and protects the nucleus

Golgi Body

Acts as the cells post office and sorts and transport proteins.

Ribosomes

Responsible for protein sythesis and is helped by the rough endoplasmic reticulum

Lysosomes

Acts as the janitor of the cell and gets rid of waste

Rough Endoplasmic Reticulum

Modifies, change and synthesis proteins and

Smooth Endoplasmic Reticulum

Makes fat and detoxes chemicals in the cell

Cytoplasm

Gel like fluid that supports organelle and gives the cell its shape

Mitochondria

Known as the powerhouse of the cell and break down glucose into Adenosine Triphosphate (energy)

Vacuole

Acts as a storage for water, nutrients and waste

Cell Membrane/Cell Wall

Cell membrane is for animal and plants, cell wall is for plants. A double layer wall that controls what enters and leaves the cell

Chloroplasts (Plants)

Chloroplasts are organelles in plant cells where photosynthesis occurs, using light energy to make glucose from carbon dioxide and water.
