Development of the Cell Theory

Importance of the Cell Theory

- All cells perform the following functions:

            - they digest nutrients

            - get rid of (excrete) wastes

            - make the chemicals they need (synthesize)

            - reproduce

-Cells define life and death

            - 10 trillion cells in the human body, different cells have different functions

            - all life is composed of at least one cell

            - bacteria and fungus living on your body

Abiogenesis: is a theory that states that nonliving things can spontaneously change into living things.

●          Outline the events leading to the theory of abiogenesis.

- A hypothesis is a possible solution to a problem or an explanation of an observed phenomenon.

- Experimental variables are designed to test a hypothesis. Experimental groups test a single variable at a time.

- Controls are standards used to verify a scientific experiment. Controls are often conducted as parallel experiments.
