QUEST REVIEW WITH
MISS DELL
- If you did not do your homework
- If you got one or more wrong the
QUEST check
- You would like a further review of
the Characteristics of Living Things
All other students
- Work on your QUEST
- Read Pages 7-11 and Answer Question 4
- Watch Wacky History of the Cell Theory

1. Living things are Organized
Cell- basic unit of structure and
function in an organism.
Living thing are made up of small units
called cells. Each cell has an orderly
structure and contains genetic
material – a blueprint for the cell’s
organization and function.
Unicellular – one cell.
EXAMPLE: Bacteria
Multicellular – more than one cell.
EXAMPLE: Humans!
Entamoeba gingivalis
2. Living Things Contain Similar Chemicals
a. WATER- most
b.
c.
d.
e.
abundant
chemical in
cells
Carbohydrates
Proteins
Lipids
Nucleic Acids
(DNA)
3. Living things use energy
3. Living things use energy
 List 3 things for which cells use energy:
 REPAIR
 GROWTH
 MOVEMENT OF MATERIALS; BUILDING
MOLECULES
4. All living things respond to
their surroundings
 Stimulus- a change in an organism’s surroundings
that causes the organism to react
 Response- an action or change in behavior
5. Living things
Grow and develop
 Growth- the
process of
becoming larger
 Development- the
process of change
that occurs during
an 0rganism’s life
to produce more
complex organisms
6. All living things reproduce
The ability to produce offspring that are similar to the
parents.
Spontaneous Generation Theory
Idea that life can spring from nonliving matter.
Most people believed in this theory until the 1600s!
What observations could have supported this
theory?
For example, People believed:
-Mice came from straw
-Frogs and turtles developed from rotting wood
and mud at the bottom of a pond.
-Flies came from rotten meat.
Francesco Redi’s Experiment
How did this experiment disprove spontaneous
generation?

How are multicellular organisms
organized?
Are we just a pile of cells?
6. In Multicellular Organisms:
Cells  Tissues  Organs  Organ Systems
7.
• Cell- the basic unit of structure and function in living
things (Ex. Nerve Cell)
• Tissue- Group of similar cells that work together to
perform a specific function (Ex. Nervous Tissue)
• Organ- Different tissue that work together (Ex. Brain)
• Organ System- Group of organs that work together to
perform a major function (Ex. Nervous System)
