Write down anything that is underlined in your notes (OneNote/composition book)

Cell Theory

• Cells are the smallest unit of life

• All living things are made of 1 or more cells

• Cells come from preexisting cells

Prokaryote vs Eukaryote

Prokayrotes

• No nucleus

• No membrane bound organelles

• Single celled only

• (Bacteria & Archaea)

Eukayrotes

• Nucleus

• Membrane bound organelles

• Unicellular or multicellular

• (Protist, Fungi, Plants & Animals)

Kingdoms

• Prokayrotes: Bacteria & Archaea

• Eukaryotes: Protists, Fungi, Plants & Animals

Plant cells

• Cell wall

• Chloroplast (for photosynthesis)

• Large central Vacuole

Multiple Choice

When cells are damaged, new cells are created by cell division. How does the cell theory support this fact?

• It states that all cells have a nucleus which divides.
• It states that all living things are made up of one or more cells.
• It states that cells come from previously existing cells.
•  It states that the basic units of structure and function are cells.
