What structure in plant cells is responsible for maintaining turgor pressure?

The large central vacuole is crucial for maintaining turgor pressure in plant cells. This vacuole serves as a storage place for water, nutrients, and waste products. When the vacuole is filled with water, it exerts pressure against the cell wall, creating turgor pressure that supports the plant's structure, helps maintain its shape, and keeps it upright. This pressure is vital for photosynthesis, growth, and the overall health of the plant.

While chloroplasts are important for photosynthesis, they do not play a direct role in maintaining turgor pressure. The Golgi body is involved in the modification and transport of proteins and lipids but does not regulate turgor pressure either. The cell membrane provides some support and controls the movement of substances in and out of the cell, but it is the large central vacuole that is primarily responsible for generating and maintaining the pressure needed to keep plant cells firm and functional.
