Explain differentiation by giving one example.
✓

Answer

The process in which the cells or tissues become structurally and functionally different is called differentiation.
 In the plant body, all the cells are derived from the single-cell zygote. After division, the zygote undergoes some structural and functional changes, which are collectively called 'differentiation'. Example: In xylem elements, the changes in thickening occurs and perform the function of conduction of water, storage of food, etc.
