2. • Outer
Cell Membrane boundary of
cell
• Protects the
cell
• Controls what
enters and
leaves the
cell

3. Cell Wall
• Only found in
plant cells
• Adds protection
and support
• Made of
cellulose
• Allows water
and dissolved
substances to
pass through.

4. The Nucleus
• Controls most
activities in the cell
• Contains all
genetic information
in the form of DNA.

5. Cytoplasm
• Clear fluid within
cell that contains all
organelles
• Moves materials
throughout the cell

6. Endoplasmic Reticulum
• Series of folded
membranes that form sacs
or tubes
• Packages proteins for the
Golgi Complex
• Rough ER has ribosomes
attached; smooth ER does
not have ribosomes

7. Ribosomes
• Transports materials
between the cytoplasm
and nucleus
• Makes proteins in the
cell
• May be free in
cytoplasm or attached
to ER (rough ER)
• Proteins are vital to life-
all cells must produce
them

8. Golgi
Complex
• Saclike membranes
used for storing/
packaging of
chemicals
• Cells that make
saliva or mucus
have many Golgi
complexes

9. Mitochondria
• Energy producers
(“mighty
mitochondria”)
• Powerhouse of the
cell
• Sausage-shaped
• Many mitochondria in

10. Vacuoles
• Store food,
water, or waste
materials
• Plant cells have
large vacuoles

11. • Found in Golgi
Lysosomes complex
• Contain digestive
enzymes to digest
food particles &
wastes
• Help white blood
cells to destroy
bacteria
• Clean up cell like
Lysol (lysol =
lysosome)

12. Chloroplasts
• Organelle where
photosynthesis
takes place
• Chlorophyll inside
chloroplast gives
plant its green color
• Only in plant cells
