1. Normally the meristematic cells are oval, polygonal or rectangular in shape. 2. Their research demonstrated the world's first cambial meristematic cell isolation. 3. Prior to fruiting, its principal function is to grow meristematic tissues. 4. Dense protoplasm of meristematic cells contains very few vacuoles. 5. Meristematic cells are packed closely together without intercellular cavities.6. In higher plants this function is the defining property of the meristematic cells. 7. In fact, a typical shoot meristematic plant cell contains only 7 20 proplastids. 8. These alterations indicate intense metabolic activity, appearing to dedifferentiate and resemble meristematic cells. 9. Meristematic cells give rise to various organs of the plant and keep the plant growing.10. These plantlets arise from mitosis of meristematic -type tissue in notches in the leaves.
