phospholipid bilayer

Question 13

functions in packaging of small molecules for transport

Answer 13

Golgi Apparatus

transports materials (usually in vesicles) to destinations in the cell OR to the cell membrane for export

Question 14

Describe the function of this cell part:

lysosome

Answer 14

functions in intracellular digestion

Question 15

Describe the function of this cell part:

Endoplasmic Reticulum

(rough)

Answer 15

functions to compartmentalize the cell

and

play a role in intracellular transport

Question 17

functions in intracellular digestion

Answer 17

lysosome

Question 18

Smooth Endoplasmic Reticulum

Answer 18

synthesizes lipids

modifies molecules - chemically changes them

Question 20

functions to compartmentalize the cell

and

play a role in intracellular transport

Answer 20

Endoplasmic Reticulum

(rough)

Question 21
