Final answer:
The plasma membrane, cytoplasm, and central vacuole work in unison to prevent a plant cell from bursting by balancing internal water pressure and supporting the plant's structural integrity.
Step-by-step explanation:
The three organelles that work together to prevent a plant cell from bursting when it has too much water are the plasma membrane, cytoplasm, and the central vacuole filled with cell sap that maintains pressure against the cell wall. The plasma membrane regulates the passage of substances into and out of the cell, while the cytoplasm contains solutes that contribute to the osmotic balance. The central vacuole's chief role is storing water and maintaining turgor pressure, which is essential for the plant's structural integrity. When water enters the cell, the vacuole expands, exerting pressure against the cell wall and plasma membrane. However, because of the rigid cell wall, the plant cell doesn't burst but instead becomes turgid, which actually helps support the plant structure overall.
