3 Written Questions

1. Network of membranous sacs and tubes; active in membrane synthesis and other synthetic and metabolic processes; has rough (ribosome-studded) and smooth regions. Rough ER grows in place by adding proteins and phospholipids.
2. Transfers membrane segments as tiny vesicles (sacs made of membrane). Transport vesicle: transport secretory proteins from one part of the cell to another.
3. Digestive organelle where macromolecules are hydrolyzed.

2 Multiple Choice Questions

1. Nonmembranous organelle involved in production of ribosomes; a nucleus has one or more nucleoli.
   1. Nucleolus
   2. Chromatin
   3. Vesicle
   4. Lysosome
2. Organelle active in synthesis, sorting, and secretion of cell products. After leaving ER, many transport vesicles travel to Golgi apparatus.
   1. Lysosome
   2. Golgi Apparatus
   3. Chromatin
   4. Nucleolus
