History of the Cell
• The Cell
–The basic unit of an organism
–The discovery of the cell was
made possible by the invention
of the microscope.
Glue in your scientists!
Anton van
Leeuwenhoek
Robert Hooke
Microscopes and Cells
• 1600’s- Anton van
Leeuwenhoek first
described living
cells as seen
through a simple
microscope.
Microscopes and Cells
–Robert Hooke used the first
compound microscope to view thinly
sliced cork cells.
• Compound scopes
use a series of lenses
to magnify in steps.
• Hooke was the first
to use the term “cell”.
Microscopes and Cells
• 1830’s - Mathias Schleiden
identified the first plant cells and
concluded that all plants are made
of cells.
- Thomas Schwann
made the same
conclusion about
animal cells.

Bellwork 11/3/15
1. What discovery is Robert Hooke
responsible for?
Robert Hooke observed empty
spaces in a slice of cork and called
them “cells”.
2. Who identified that all animals are
made of cells?
Thomas Schwann concluded that all
animals are made of animal cells.

Cell Theory
1. All organisms are made up of one or
more cells.
2. The cell is the basic unit of organization
of all organisms.
3. All cells come from other cells already in
existence.
Two Basic Cell Types
1. Prokaryote
– Lacks internal
compartments.
– No true nucleus.
– Most are single-celled
(unicellular) organisms.
– Examples: bacteria
Two Basic Cell Types
2. Eukaryote
–Has several internal
structures
(organelles).
–True nucleus.
–Either unicellular or
multicellular.
•unicellular example:
yeast
•multicellular examples:
plants and animals

Levels of Organization
https://www-brainpopcom.sled.idm.oclc.org/science/cellularlifeandgenetics/cells/
Did you know that you have 75 trillion cells
that make up your body?! (that is thousands of
times more than the number of people on the
planet!)
5 Levels of Organization
Cells
Tissues
Organs
Organ Systems
Organism
Organism
• A living system that
has several organ
systems that function
together.
• Examples: Animals,
plants, and bacteria
Organ System
• A group of organs that
carries out more
generalized set of
functions.
• Examples: digestive
system and circulatory
system.
Organ
• Organs are two or
more types of tissues
that work together to
complete a specific
task.
• Examples: heart or
stomach.
Tissue
• Groups of cells with
similar functions.
• Examples: Connective
(bone, blood) and muscle
tissue.
Cells
• The smallest unit of
life. Cells preform
specific functions.
• Example: muscle
cell or skin cell
