.

All living things are made of cells.

The cell is the smallest thing that can be considered a living thing.

Multiple Choice

What is an organism?

• a cell

• a part of a cell

• a living thing

Multiple Choice

What are organisms made of?

• DNA

• cytoplasm

• cells

• nuclei

Organisms are made of cells

• Organisms can be made of one cell (unicellular)

• Organisms can be made of many cells (multicellular)

Multiple Choice

What does multicellular mean?

• Made of one thing

• Made of cells

• Made of a single cell

• Made many things

Multiple Choice

What does unicellular mean?

• made of one thing

• made of many things

• made of a cell

• made of cells

Two Main Types of Cells

• Prokaryotic Cells

• Eukaryotic Cells

Prokaryotic Cells

• no nucleus so the DNA floats freely in the cell

• simple cells

• no membrane bound organelles

• organisms such as bacteria, paramecium, and amoeba are made of a prokaryotic cell

Eukaryotic Cells

• have a nucleus to contain the DNA

• complex/complicated cell

• has many parts (organelles)

• organisms such as humans, animals and plants are made of multiple eukaryotic cells

Multiple Choice

Which type of cell has a lot a complex parts?

• Prokaryotic

• Eukaryotic

Multiple Choice

Which type of cell does not have a nucleus?

• prokaryotic

• eukaryotic

Multiple Choice

Prokaryotic and Eukaryotic cells do have some similarities.

Multiple Select

Eukaryotic and Prokaryotic cells have the following parts in common:

• cell membrane
