The Cell Theory
The cell theory has 3 major tenets:
1. All living things are composed of one or more
cells.
2. Cells are the basic unit of structure and function in
living things.
3. New cells are produced from existing cells.
The ability of cells to divide to form new cells is the basis
for all reproduction (both sexual and asexual) and for the
growth and repair of all multicellular organisms.
Unicellular vs. Multicellular
It is the LOWEST LEVEL of structure capable of life.
Don’t forget: Unicellular organisms are made up of one cell only
Multicellular organisms are made up of many cell, like us!
Prokayotic vs. Eukaryotic Cells…
a song too
2 Main Types of Cells
Both main types of cells contain cell membrane, DNA,
cytoplasm, and ribosomes.
1. Prokaryotic Cells
Do not have a true nucleus
So, the cell’s DNA is not completely separated from
the rest of the cell by a nuclear membrane (envelope)
DNA is circular, floats within cell.
DNA (deoxyribonucleic acid) is a chemical compound
that stores and transmits genetic information
2 Main Types of Cells
2. Eukaryotic Cells
Have a nucleus
DNA is arranged in strands called chromosomes
DNA is housed in the nucleus and separated from the
rest of the cell by a cell membrane
A Little More about Prokaryotic Cells…
Prokaryotic cells:
lack most organelles
Organelles = tiny “organ-like” structures
in the cell
do not contain mitochondria but
obtain energy from either sunlight
or from chemicals in their
environment.
contain ribosomes which create
proteins
Most prokaryotes are unicellular
organisms, such as bacteria.
Much smaller than eukaryotic
cells
2 Types of Eukaryotic Cells
Eukaryotic cells are much more complex and larger than
their simple cousins the prokaryotic cell.
They contain membrane-bound organelles (including
mitochondria and chloroplasts)
Most are Multicellular, few unicellular
We will talk more about the inner workings of the
eukaryotic cell tomorrow, but for now we are going to
learn the basics of the 2 types of eukaryotic cells:
Plant Cells
Animal Cells
Plant vs. Animal Cells Rap
Plant vs. Animal Cells
Plant Cells:
Have a cell wall, which helps with
cell support
Have a central vacuole, which
acts as a water storage center for
the plant cell
Contain chloroplast, where
photosynthesis takes place
Photosynthesis = process
through which plants get their
energy by converting sunlight
and energy into glucose
Plant vs. Animal Cells
Animal Cells:
Do not have a cell wall
Do not have a central vacuole,
but may have a few tiny
vacuoles/vesicles
Do not contain chloroplasts
