Question

what is the main function of ribosomes in a plant cell?
to make proteins

to contain the information that the cell uses for growth and activities

to use energy from sunlight to make sugar

to make lipids

Explanation:

• Ribosomes are cellular structures responsible for protein synthesis (translation) in cells, including plant cells.
• The option "to contain the information that the cell uses for growth and activities" describes DNA (in the nucleus), not ribosomes.
• "To use energy from sunlight to make sugar" is the function of chloroplasts (photosynthesis), not ribosomes.
• "To make lipids" is the function of the smooth endoplasmic reticulum, not ribosomes. So the correct option is the one stating ribosomes make proteins.

Answer:

to make proteins
