This document provides information about cells and their structure and function. It discusses key topics like the cell theory, discovery of cells using microscopes in the 1600s and 1800s, parts of animal and plant cells and their functions, and comparisons between plant and animal cells. The document also includes true/false questions about species and provides guidelines for using a microscope properly.

1. Structure and Function
of Cells

2. Species
Group of
organisms
Share certain
characteristics
Can mate and
produce offspring

3. SO…..True or False
A = True
B = False
Members of different species that mate
can produce fertile offspring.
Members of the same species share
similar characteristics.
A dog and a cat are the same species.

5. Cell Theory
Theory stating
All living things
are made of cells
that the cell is the
basic unit of all
living organisms,
only living cells
can produce new
living cells

6. Cell Theory
1663 – Robert Hooke discovers cells
1683 – Leeuwenhoek observes “very little
animalcules”
1831 – Brown discovers the cell nucleus
1838 – Schleiden and Schwann propose
the cell theory
1855 – Virchow states that cells could
come only from other living cells

7. Microscopes
Compound
Microscope =
microscope having
more than one lens
Parts of the
microscope

8. Microscope Guidelines
Hold arm with one
hand and base
with other hand
DO NOT set on
edge of table or
counter
ALWAYS store on
low power
Focus FIRST on
low power using
course adjustment

9. Microscope Guidelines
Adjust diaphragm
under the stage to
adjust the amount
of light
Turn to medium
power, then high
power using fine
adjustment for
exact focusing
Clean eyepiece
and objectives with
lens paper ONLY!

10. Parts of Animal/Plant Cells and their
Function
Animal Cell
Handout
Plant Cell Handout

11. Comparison of Plant And Animal Cell
PLANT ANIMAL

12. Plants…
Why are they important??
