5. Cells
 All living things are formed by cells. They are the
basics unts of life.
 Unicelular: 1 cell.
 Multicelular: more than 1 cell.
 They perform basic life processes.

6. Parts of a cell
Membrane: surrounds and protects the cell.
Membrane
Nucleous: controls everything.
Cytoplasm: thick, clear liquid inside the
membrane. We find nucleous and
organelles.

tissues that work
together to
perform an action.

10. The 5 kingdoms
 We can clasify living things into 5 kingdoms.
Moneran kingdom
• Unicellullar.
• Bacteria.
Protist kingdom
• Unicellular-multicellular.
• Protozoans and algae.
Fungus kingdom
• Unicellular-multicellular.
• Yeast and mushrooms.
