Meristematic tissues lack vacuoles due to their highly active and dividing nature. These specialized plant cells undergo rapid cell division in the growing regions, such as the root and shoot tips, to facilitate continuous plant growth and development. During this active phase, the cell's energy and resources are primarily focused on replicating genetic material and producing new cells, leaving limited time and resources to develop and maintain vacuoles. Additionally, the absence of vacuoles allows meristematic cells to have more space for expansion, ensuring their efficient contribution to plant growth and differentiation without the constraint of large vacuoles occupying cellular space.
