• Meristematic tissues are responsible for plant growth
• Apical meristem tissues are located at the tips of roots and shoots
• Lateral meristem tissues consist of cork cambium and vascular cambium
• Growth that happens in zone of cell division , zone of cell elongation and zone of cell differentiation is the primary growth of plants
• The zone of cell division takes place at the apical meristems which consist of actively dividing meristem cells through mitosis
• The increase of the number of cells causes the elongation of the plant stem
• When new cells are forming , the new cells formed previously are pushed to the zone of cell elongation
• The zone of cell elongation consist of cells that are increasing in size. The increase in size happens through water diffusion by osmosis and the absorption if nutrients into the fells and stored in the vacuoles
