GENERAL HISTOLOGY

Detailed explanation-1: -Definition. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

Detailed explanation-2: -The central vacuole stores water and maintains turgor pressure in a plant cell. It also pushes the contents of the cell toward the cell membrane, which allows the plant cells to take in more light energy for making food through photosynthesis.

Detailed explanation-3: -Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

Detailed explanation-4: -Most mature plant cells have a central vacuole that occupies more than 30% of the cell’s volume. The central vacuole can occupy as much as 90% of the volume of certain cells. The central vacuole is surrounded by a membrane called the tonoplast.

Detailed explanation-5: -Vacuoles store water Vacuoles in plant cells are large because their main function is to store water for the plant. The central vacuole in a plant cell can take up to 30 to 90 percent of the area of the cell.
