Cell

Smallest living part of an organism

Many forms

• Nerve cell
• Fat cell
• Blood cell
• Etc.

Cells

Organisms are made up of many cells.

Cells contain organelles

Organelles = the 'organs' of cells

cell membrane

cell wall

nucleus

cytoplasm

chloroplast

vacuole

Different cells for different groups

Keeps outside of the cell sturdy (strong and rigid)

Thin layer around the cell.

Gel-like liquid inside the cell that contains all other organelles.

Control center of the cell, contains the DNA

Performs photosynthesis (process of making food), only found in plants

Turns food into energy, so organisms can do things

Stores water, food and other substances

Bacteria do have DNA but it is not contained inside a nucleus

Many animals have specialized cell types that help them be sturdy (for example bone cells)
