Question

what is the main function of the nucleus in a plant cell?
to give strength and stiffness to the cell
to direct cell activities by sending instructions to different parts of the cell
to store waste in the cell
to use energy from sunlight to make sugar

Explanation:

• Analyze each option:
• "to give strength and stiffness to the cell" is the function of the cell wall, not the nucleus.
• "to direct cell activities by sending instructions to different parts of the cell" matches the nucleus's role as the control center of the cell, containing genetic material that regulates cell functions.
• "to store waste in the cell" is not a function of the nucleus (vacuoles often store waste).
• "to use energy from sunlight to make sugar" is the function of chloroplasts in photosynthesis.

Answer:

B. to direct cell activities by sending instructions to different parts of the cell (assuming the second option is labeled B; adjust the label based on actual numbering if needed, but the text of the correct option is "to direct cell activities by sending instructions to different parts of the cell")
