Verified step by step guidance

Understand the role of the plant vacuole: The vacuole is a membrane-bound organelle in plant cells that serves several functions, including maintaining turgor pressure, regulating cytosolic pH, and storing nutrients and solutes.

Define turgor pressure: Turgor pressure is the pressure of the cell contents against the cell wall in plant cells, which is crucial for maintaining the plant's structure and rigidity.

Explore pH regulation: The vacuole helps in regulating the cytosolic pH by sequestering excess ions and maintaining an acidic environment within itself, which is important for cellular homeostasis.

Consider nutrient and solute storage: Vacuoles store a variety of substances, including nutrients, ions, and waste products, which are essential for the cell's metabolism and overall function.

Identify the incorrect function: Supporting protein transfer is not a primary function of the plant vacuole. Protein transfer is typically associated with other organelles like the endoplasmic reticulum and Golgi apparatus.
