Cell Theory
All living things are made of
cells.
All cells come from
preexisting cells.
The cell is the basic unit of
organization in living things.
Two Types of Cells
Prokaryote
Cells that lack internal structures
surrounded by membranes.
Cells with no defined
nucleus. The DNA
is a circular strand.
Eukaryote
Cells with
organelles
surrounded by
membranes.
Animal Cells
k
This
is what your
animal cells
should have
looked like!
Can you identify
any parts?
Plant Cells
This is what
your plant cells
should have
looked like.
What are the
green
structures?

Parts of a cell:
Boundries
Divide this page
into two sections
Plasma Membrane
Selectively permeable
Controls what enters
and leaves the cell.
Maintains chemical
balance.
Defines the boundary
of the cell.
Cell Wall
Gives a firm
structure to
plant cells.
Made mainly of
cellulose.
Divide this page into
two sections
Cytoplasm
Jelly-like
substance that
supports the
organelles.
Many chemical
reactions take
place in the
cytoplasm.
Cytoskeleton
Support
Scaffolding in
the cytoplasm
Divide this page into
two sections
Chloroplast
Contain pigments
that absorb energy
needed to run
photosynthesis.
Found in plants
and some
protozoans.
Mitochondria
Produces energy
for the cell.
Divide this page into
two sections
Endoplasmic reticulum
System of passages
that transport
substances around
the cell.
Two types:
smooth
rough (has ribosomes)
Ribosomes
Protein synthesis
Storage & Digestion
Divide this page into
three sections
Vacuoles
Membrane
bound
containers for
storage and
transport of
substances in
the cell.
Lysosome
Vacuole that
contains
digestive
enzymes.
Golgi Apparatus
Membrane sacks
that store newly
produced
proteins.
This page will have one
drawing in the middle
with four sections
surrounding it.
Nucleus
Control center for the
cell.
Contains the
information for all cell
activities.
Has a double,
selectively permeable
membrane.
Nucleolus
Produces
ribosomes
Chromatin
Long strands of DNA
that hold the
directions for all cell
activity.
Centrioles
Involved in cell
division
