Question

the diagram shows a plant cell.
which structure controls many activity of the cell?
① structure 1
② structure 2
③ structure 3
④ structure 4

Explanation:

In plant cells, the mitochondrion (usually labeled appropriately in cell diagrams) is the organelle that controls energy activity (cellular respiration to produce ATP). Assuming structure 3 is the mitochondrion (common labeling in plant cell diagrams for energy - producing organelle), it's the one that controls energy activity.

Answer:

structure 3 (assuming the options are labeled as structure 1, structure 2, structure 3, structure 4 and structure 3 is the mitochondrion - related structure for energy activity in the plant cell diagram)
