CELL THEORY

• ALL living things are made of 1 or more cells• CELLS come only from other

living cells• A CELL is the basic unit of

structure and function in all living things

Page 6: ROBERT HOOKE 1 st to see cells. Cork Cells Cork cells. Are they living? Which cell part are we seeing here?

A THEORY

• Is NOT an educated Guess.

Page 7: ROBERT HOOKE 1 st to see cells. Cork Cells Cork cells. Are they living? Which cell part are we seeing here?

A THEORY

• * Explains many observations

• * Is Testable

• * Could be disproven

• * Allows us to make accurate predictions
