Cell Organelles
2
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

Cell Membrane

• Every cell is enclosed by a cell membrane. It
  controls the passage of materials in and out of
  the cell.

6
Cell Membrane
7
Nucleus

• The control center of the cell. It contains the
  DNA code for the cell coiled into chromosomes.

8
Cytoplasm(not an organelle - but important)

• All organelles reside (live and float around in)
  the cytoplasm.

9
Mitochondria

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

10
Mitochondria
11
Mitochondria
12
Golgi Complex

• The protein packaging and transport center of the
  cell.
• Has incoming and outgoing vesicles.

13
Golgi Complex
14
Ribosomes(not an organelle - but important)

• Synthesizes proteins.
• Present in the cytoplasm.
• Present with Rough ER.
• No membrane present.

15
Smooth Endoplasmic Reticulum

• Transports materials throughout the cell.
• Digests lipids.
• Produces proteins.

16
Rough Endoplasmic Reticulum

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

17
Rough Endoplasmic Reticulum
18
Lysosome

• Breaks down materials for digestion.
• Contains special enzymes for digestion in the
  cell.

19
Cell Wall (Plant Cell Only)

• Rigid and strong wall.
• Protects and maintains the shape of the cell.

20
Cell Wall (Plant Cell Only)
21
Cell Wall (Plant Cell Only)
22
Chloroplast(Plant Cell Only)

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

23
Chloroplast(Plant Cell Only)
24
Chloroplast(Plant Cell Only)
25
Central Vacuole(Plant Cell Only)

• Most plant cells have one large one.
• Filled w/ fluid.
• Helps maintains turgor pressure and shape of
  cell.
