The temperature reading on the thermometer
would most likely indicate the temperature
1. of a human body on a very hot summer day
2. at which water freezes
3. at which water boils
4. of a human with a very high fever
The diagram shows equal masses of four
different earth materials at different
temperatures.
2.7g/cm3
7.7 g/cm3
1.0
g/cm3
.00012 g/cm3
Which material has the greatest density?

Excretion • Removal of cellular
(metabolic) waste
Locomotion • Ability of an organism to
move
Factors that
influence
metabolism
• Gender
• Age
• Exercise
• Diet
• Drugs and alcohol
Cells
• Carry out life processes
• Make up living things
(ORGANISMS)
Just like bricks make up a brick
house, cells make up an
organism
The Robert
Cell Theory
timeline
Hooke–( a1665)
1. Cells are the basic unit of
Cell
structure in all living
Theory
things.
(Living things are made of
cells)
2. Cells are the basic unit of
function of all living things
(They carry out life
processes)
3. All cells come from
pre-existing cells.
Exceptions
to the
Cell
Theory
• Viruses:
- not composed of cells
- contain genetic information
- reproduce inside host cell
Virus do not
reproduce
by division
because
they are not
cells.
Did you know…
• The first virus was found in both
plants and animals 100 years ago.
• The common cold is a type of virus.
• Viruses can be treated with antiviral
drugs.
Let’s summarize…
1. What do all organisms consist of?
2. Explain the three parts of the cell
theory.
3. Explain why viruses are exceptions
to the cell theory.
Review:
Which statement is not a part of the cell
theory?
1. Cells are the basic unit of structure of living
things.
2. Cells are the basic unit of function of living
things.
3. Cell parts such as chloroplasts are selfreplicating.
4. Cells come from preexisting cells.
2. The cell theory states that all
living things are made up of
1. organisms
2. cells
3. tissues
4. proteins
3. Which choice is NOT part of cell
theory?
1. Cells are the basic units of life.
2. All living things are made of one or
more cells.
3. All cells come from other living cells.
4. New cells have the same nuclei as those
of pre-existing cells.
