Cell organelles

Cell Organelles

1. Cell Organelles
What you need to know

2. An organelle is a membrane-
bound structure that carries out
specific activities for the cell.

3. You will need to know the following organelles and their
function:
Cell Membrane
Nucleus
Cytoplasm
Mitochondria
Golgi Complex
Ribosomes
Smooth Endoplasmic Reticulum
Rough Endoplasmic Reticulum
Cell Wall
Chloroplast
Central Vacuole
Lysosome

4. Cell Membrane
Every cell is enclosed by a cell membrane. It
controls the passage of materials in and out of the
cell.

5. Nucleus
The control center of
the cell that contains
DNA
(chromosomes) and
the nucleolus.

6. Cytoplasm
(not an organelle - but important)
All organelles
reside (live
and float
around in) the
cytoplasm.

7. Mitochondria

This organelle
processes energy
for a cell. It makes
ATP.
(ATP = energy)
Involved in cellular
respiration.

8. Golgi Complex
The protein
packaging and
transport center of
the cell.
Has incoming and
outgoing vesicles.

9. Ribosomes
Synthesizes proteins.
Present in the
cytoplasm.
Present with Rough
ER.
No membrane present.

10. Smooth Endoplasmic Reticulum
Transports materials
throughout the cell.
Produces lipids and
hormones

11. Rough Endoplasmic Reticulum

Covered with
ribosomes.
Produces proteins.
Transports materials
throughout the cell.

12. Lysosome
Breaks down
materials for
digestion.
Contains special
enzymes for
digestion in the cell.

13. Cell Wall (Plant Cell Only)
Rigid and strong
wall.
Protects and
maintains the shape
of the cell.

14. Chloroplast (Plant Cell Only)

Contains chlorophyll.
Makes plants green.
Uses light energy to
make ATP & sugars.
Photosynthesis takes
place here.

15. Central Vacuole (Plant Cells)
Most plant cells
have one large one.
Filled w/ fluid.
Helps maintains
turgor pressure and
shape of cell.
