The following points highlight the top six factors influencing differentiation of sclereids cells in plants. The factors are: 1. Ageing 2. Wounding 3. Position 4. Osmotic Pressure 5. Enzyme 6. Hormone. Factor # 1. Ageing: In the barks many parenchyma cells change to brachysclereids. It is regarded that the sclereid differentiation is due to ageing of the tissues. Factor # [...]
