Why do meristematic cells lack vacoules?

Description : Why do meristematic cells lack vacoules?

Last Answer : The purpose of vacuole is to store food and waste product. Since meristems are young cells and are actively dividing, they do not partcipate actively in food preparetion. Neither they produce large waste and hence lack vacuoles.
