1. Science Quiz Review Notes

2. Animal Cell Plant Cell
Cells – a membrane covered structure that
contains all materials necessary for life.

3. Organism – A living thing

4. Reproduction
Asexual Reproduction:
A single parent produces
offspring (new organism)
that are identical to the
parent
Sexual Reproduction:
Two parents that produce
offspring (new organism)
that share characteristics
of both parents

5. DNA – a molecule found in the cells of all
living things. It provides all instructions
for making proteins.

6. Stimulus
A change in an organism’s environment that affects
the activity of the organism.

7. Unicellular Organisms Multi-cellular Organism
An organism made of
one cell.
An organism made of
many cells.
Cellular Organisms

8. Eukaryotic Cell Prokaryotic Cell
A cell that contains a
nucleus and a
complicated internal
structure
Ex. Plant and Animal
cells
A cell that does not have
a nucleus and does not
have membrane-covered
organelles
Ex. Bacteria
Cells

9. Organelle
A structure (mini-organ) within a cell, sometimes
surrounded by a membrane.

10. Chromosomes
Packages of coiled DNA found in the nucleus of a cell.

11. Cell Theory
1. All organisms are composed of one or more cells.
2. The cell is the basic unit of life in all living things.
3. All cells come from existing cells.
(You must know the parts of cell theory)

12. Additional Information to Review
 Know how to calculate the total magnification on a
microscope
(multiply the eyepiece magnification by the magnification of the objective)
 Know the reason why we place a cover slip, onto a
slide, at an angle (to avoid having air bubbles)
 Cells join to form tissues; tissues join to form organs;
organs join to form organ systems
