AThe Golgi apparatus
BThe nuclear envelope
CThe mitochondrion
DThe central vacuole
Answer & Solution
Correct answer: A. The Golgi apparatus
1. Proteins leaving the endoplasmic reticulum still need to be sorted, packaged, and tagged.
2. Sorting, tagging, packaging, and distribution of lipids and proteins takes place in the Golgi apparatus.
3. Vesicles from the endoplasmic reticulum fuse with the receiving face, and finished cargo leaves from the shipping face.
4. Cells that secrete heavily, such as salivary gland cells, carry an abundance of Golgi.
5. The nuclear envelope wraps the DNA and the central vacuole stores water, so neither runs the shipping room.
