Review Practice

Which of the following MOST accurately explains the proximity of the Golgi apparatus to the RER and the cell membrane?

• The Golgi apparatus needs to be close to teh RER so that it can modify the lipids that are produced by the RER before they will be exported from the cell. The Golgi will further modify the lipids and then create vesicles that will fuse with the cell membrane to efficiently excrete the products. 
• The Golgi apparatus is close to the RER so that it can properly translate the proteins as directed by the DNA instructions received by the RER from the nucleus. The Golgi apparatus is close to the RER so translation can take place quickly. Once the proteins are produced, they can be sent out of the cell by fusing with the cell membrane.
• The Golgi apparatus is close to the cell membrane so it can fuse with the vesicles or imported materials. This allows the Golgi apparatus to quickly break down the imported materials so they can be sent to the RER for further processing. The RER will use the imported materials to make proteins for the cell.
• The Golgi apparatus needs to be close to the RER as it receives proteins that have been produced and modified by the RER that will be exported from the cell. Once the contents of the vesicles are received from the RER and move through the Golgi apparatus, they are then excreted from the Golgi apparatus via vesicles that will fuse with the cell membrane for export out of the cell. The closeness of these organelles is directly related to the needs of the cell to export material efficiently.

What is plasmolysis?

• Pulling away of the plant cell membrane as it loses water in a hypertonic solution.
