Question

what is the main function of ribosomes in a plant cell?
to control which substances enter and leave the cell
to give structure and organization to the cell
to make proteins
to give strength and stiffness to the cell

Explanation:

To determine the main function of ribosomes in a plant cell, we analyze each option:

• "to control which substances enter and leave the cell" is the function of the cell membrane.
• "to give structure and organization to the cell" is not the function of ribosomes (e.g., the cytoskeleton or cell wall has structural roles, but not ribosomes).
• Ribosomes are known as the "protein - making factories" of the cell. They are responsible for protein synthesis.
• "to give strength and stiffness to the cell" is the function of the cell wall (in plant cells).

So the correct option is the one that says "to make proteins".

Answer:

to make proteins
