Question

what is the main function of the rough endoplasmic reticulum in a plant cell? to store water, waste, and nutrients, such as sugar, in the cell to fill the space between the cell membrane and the nucleus to give strength and stiffness to the cell to help ribosomes make proteins

Explanation:

1. Analyze the first option: Storing water, waste, and nutrients (like sugar) is the function of a vacuole, not the rough endoplasmic reticulum (RER).
2. Analyze the second option: The cytoplasm fills the space between the cell membrane and the nucleus, not the RER.
3. Analyze the third option: Giving strength and stiffness to the cell is the role of the cell wall (in plant cells), not the RER.
4. Analyze the fourth option: The rough endoplasmic reticulum has ribosomes attached to its surface, and its main function is to assist ribosomes in protein synthesis.

Answer:

The correct option is: to help ribosomes make proteins
