Detailed explanation-1: -In general, plant cells have one larger central vacuole.
Detailed explanation-2: -Most mature plant cells have one large vacuole that typically occupies more than 30% of the cell’s volume, and that can occupy as much as 80% of the volume for certain cell types and conditions. Strands of cytoplasm often run through the vacuole.
Detailed explanation-3: -Many plant cells have a large, single central vacuole that typically takes up most of the room in the cell (80 percent or more). Vacuoles in animal cells, however, tend to be much smaller, and are more commonly used to temporarily store materials or to transport substances.
Detailed explanation-4: -In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell’s volume. The vacuole holds large amounts of water or food.
Detailed explanation-5: -Central vacuoles are large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell. A fluid-filled central vacuole exerts pressure on the surrounding components of the cell and the cell wall.
