Detailed explanation-1: -The large central vacuole is surrounded by its own membrane and contains water and dissolved substances. Its primary role is to maintain pressure against the inside of the cell wall, giving the cell shape and helping to support the plant.
Detailed explanation-2: -Plant cells contain vacuoles. Most adult plant cells have one large vacuole that takes up more than 30% of the cell’s volume. At certain times and conditions the vacuole takes up as much as 80% of the cell’s volume! In addition to storing wastes and water, the vacuole also helps to support the cell.
Detailed explanation-3: -The central vacuole contains cell sap that is surrounded by a single layer membrane called the tonoplast. The central vacuole’s main function is to maintain turgor pressure within the plant cell. This helps the plant cell to maintain its shape.
Detailed explanation-4: -Plant cells have a strong cellulose cell wall on the outside of the cell membrane. This supports the cell and stops it bursting when it gains water by osmosis.
Detailed explanation-5: -Water is responsible for cell structural support in many plants, creating a constant pressure on cell walls called turgor, which makes the plant flexible yet strong and allows it to bend in the wind or move leaves toward the sun to maximize photosynthesis.
