Which of the following best describes how the central vacuole supports the structure of a plant cell?
The central vacuole uses a network of protein fibers to support the shape of the plant cell.
When the central vacuole is empty, it expands to fill space and maintain the cell’s structure.
The central vacuole uses a large, rigid membrane to support the shape of the plant cell.
When the central vacuole is full of water, it applies pressure to the cell wall and maintains the shape of the cell.
Eukaryotic cells contain an intricate endomembrane system that includes the nucleus, endoplasmic reticulum (ER), and Golgi complex. The Golgi complex and rough ER are often near each other, which is essential for their roles in the endomembrane system.
Which of the following most accurately explains why the Golgi complex is often near the rough ER?
The Golgi complex modifies lipids that have been produced by the rough ER.
The Golgi complex modifies and packages proteins that are produced in the rough ER.
The Golgi complex uses enzymes to digest misfolded proteins that are produced in the rough ER.
The Golgi complex translates proteins using instructions provided by the rough ER.
This organelle functions like a recycling center for the cell, breaking down old materials. It is akin to a vacuum cleaner that cleans up the waste in cells.
