Learn about the organelles of plant and animal cells.

2. PARTS OF THE CELL – CELL ORGANELLES
Nucleus • control center of the
cell – contains DNA – gives
directions for making
proteins

3. Nucleolus • inside nucleus – makes
ribosomes

4. Chromatin • inside nucleus – strands
of DNA

5. Cytoplasm • clear, gelatinous fluid
inside the cell
• gives the cell its shape
• holds or “suspends” the
cell’s organelles

6. Ribosomes • site of protein synthesis
(where protein is made)
• can be free floating or
attached to endoplasmic
reticulum

7. Endoplasmic
Reticulum
• large “workspace” inside
cell – has “folds” for
greater surface area
2 kinds of ER 1. Rough ER: has
ribosomes attached to
make protein
2. Smooth ER: no
ribosomes attached –
other biochemical
activities here

8. Golgi Apparatus
• sorts proteins to be sent
to correct destination
• flattened system of
membranes – (look like
pancakes)

9. Vacuoles • function to store
materials
• plants have a LARGE
vacuole – animal cells
have smaller vacuoles

10. Lysosome • contains digestive
enzymes
• digests/destroys
excess food, viruses,
bacteria
• also can destroy the
cell itself if needed

11. Plastids • found in PLANTS ONLY
• used for storage
EXAMPLE:
• Chloroplasts • store energy/food
• has “folds” for greater
surface area

12. Mitochondria • produces energy for the
cell
• has “folds” for greater
surface area
• each type of cell has a
different amount of these

13. Cytoskeleton • cell support structure –
gives a “framework” to the
cell
• composed of
MICROTUBULES &
MICROFILAMENTS

14. Cilia • function in movement of
the cell or line the cell to
move other things
• cilia are short, hair like
– move in waves

15. Flagella • functions in movement
of the cell
• flagella are longer –
move like a whip
