Objective: You will be able to give the functions of the cell organelles.
Do Now:• Look at the cell organelle sheet
• Give the function for as many of the cell organelles as you can remember
1. Found only in eukaryotic cells
2. A series of membrane bound organelles in close association
3. Makes and secretes proteins
4. Creates a larger cell membrane
5. Includes the nuclear envelope, E.R., Golgi, vesicles, lysosomes, vacuoles, and the plasma membrane
Figure 6.16 Review: relationships among organelles of the endomembrane system
Plasma membrane expandsby fusion of vesicles; proteinsare secreted from cell
Golgi pinches off transport vesicles and other vesicles that
give rise to lysosomes and vacuoles

Nuclear envelope
Nuclear envelope isconnected to rough ER, which is also continuous
with smooth ER

Plasmamembrane
Lysosome availablefor fusion with anothervesicle for digestion
Transport vesicle carriesproteins to plasma membrane for secretion

Group Activity• Think back to the activity in which you created
the cell park• How can you modify your park to include the
structures and functions of the endomembrane system?
• Write a small paragraph describing the endomembrane system
• Include a drawing of just the endomembrane system
Objective: You will be able to identify the parts of he mitochondria and the chloroplasts.
Do Now:• Read the section “mitochondria and
chloroplasts” on p. 179-180
• Give one similarity between these two organelles
• Mitochondria are enclosed by two membranes– A smooth outer membrane– An inner membrane folded into cristae
