Cell Theory Warm Up

An Amoeba is a unicellular, animal-like protist that lives in ponds and streams. According to cell theory, where did this cell come from?

• another pre-existing amoeba cell.
• energy from sun that allowed the protist to reproduce.
• a multicellular organism.
• the nonliving environment.

Robert Hooke, Anton van Leeuwenhoek, Theodor Schwann, Rudolf Virchow, and Matthias Schliden were all responsible for what theory?

• The Theory of Gravity
• The Theory of Relativity
• The Cell Theory
• The Theory of Continental Drift

All cells come from___________ cells.

• pregnant
• pre-existing
• paternal
• pin size

Rocks are not living because

• they never move
• they aren't needed for humans
• they are not made of cells
• they don't break down

What is one way in which all living things on Earth are alike?

• All living things have hair.
• All living things are made of cells and come from other cells.
• The cells of all living things have chloroplast.
• All living things can move. 

Which of the following statements is not part of the cell theory?

• Cells are the basic unit of structure and function in all living things.
• All cells are produced from other cells.
• Only animal cells are composed of cells.
• All living things are composed of cells.

What is the basic structural and functional unit of all living things? 

• atom
• cell
• molecule
• human

What is one way in which all living things on Earth are alike?

• All living things have hair.
• All living things are made of cells and come from other cells.
• The cells of all living things have chloroplast.
• All living things can move. 

When cells are damaged, new cells are created by cell a process called 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.

In order to be considered a living thing, that thing must

• grow and develop

• take in food and excrete waste

• reproduce

• all of the above
