Why do meristematic tissues lack vacuoles?

Open in App

Solution

● The meristematic cells divide frequently and they give rise to new cells.

●For this they require a dense cytoplasm and thin cell wall.

●Vacuoles if present will cause hinderance in cell division as it is full of cell sap to provide turgidity as well as rigidity to the cell.

●Another reason is that the main function of vacoules is to store nutrients , excess salts etc… and meristamatic cells do not need to store these nutrients because of their compact shape.
