Select the correct option: Which one of the following is not a characteristic of meristematic cells?
Meristem is a group of plant cells that exhibits continuous state of division. The tissue in the plant is called Meristem Tissue that contains the Meristem cells. These cells are found on the apex of the plant and they are very important cells for the growth of the plant. These cells are round or oval in shape. Cells does not contain any inter cellular spaces. Meristem cells are very closely packed, such that it does not have inter cellular space. They help in growth of the plant by increasing their length.
