Question

ariana garcia apontes practice p.6 compare cells and cell parts get 3 correct in a row select the one true statement. the nucleus directs a plant cells activities by sending instructions to different parts of the cell. animal cells can have mitochondria but do not have vacuoles. the cell membrane of an animal cell contains the master plan for cell activities and cell development.

Explanation:

• Analyze the first statement: The nucleus is the control center of the cell (both plant and animal) and directs cell activities by sending instructions (via DNA - based signals) to other cell parts. This is consistent with cell biology knowledge.
• Analyze the second statement: Animal cells do have vacuoles, although they are smaller and more numerous compared to plant cell vacuoles. So this statement is false.
• Analyze the third statement: The cell membrane is mainly for protection, transport, and maintaining cell shape. The "master plan" (genetic information) is in the nucleus, not the cell membrane. So this statement is false.

Answer:

The nucleus directs a plant cell's activities by sending instructions to different parts of the cell.
