Detailed explanation-1: -Vacuoles: Vacuoles are membrane-bound organelles present in both plant and animal cell. In plants, a single, large and permanent vacuole is present. It typically occupies 30% to 80% of plant cell volume.

Detailed explanation-2: -Plant cells are known to have bigger vacuoles than that of animal cells as they need to store food and water. This is because the plant don’t possess the ability to move freely like that of animals. Thus, they possess large vacuoles as a reservoir in unfavorable conditions.

Detailed explanation-3: -Why are plant cells generally larger in size compared to the animal cells? Plant cells comprise a large central vacuole that occupies a majority of the volume and makes the cell larger. This vacuole is usually absent in the animal cell.

Detailed explanation-4: -The central vacuole can occupy up to 90% of the cellular volume and, differently from intracellular organelles from animal cells such as lysosomes or endosomes, it is easy to isolate. Because of its large dimension (up to 40 m diameter) it can be successfully studied using the classical patch-clamp technique.

Detailed explanation-5: -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. Sometimes a single vacuole can take up most of the interior space of the plant cell.
