Expalin the mechanism of transportation of water and minerals and food in plants. |

Answer» Xylem transports water and minerals obtained from the soil.Phloem transports products of photosynthesis from the leaves to other parts of the plant.Vessels, tracheids of the roots, stems and leaves are connected to form a continuous system in xylem cells to transport water to all the parts of the plants.Cells in the roots which are in contact with the soil take up ions which creates a difference of concentration between the roots and the soil and therefore water moves to the roots to eliminate the difference.Water is moved into xylem of roots and from where it is pushed upward.Plants use different mechanisms to pull water upwards through xylem like-\tWater which is lost through stomata is replaced by water absorbed by the roots.\tEvaporation of water from leaf creates a suction force which pulls water.The loss of water in the form of water vapor is called The water from the soil reaches the leaves by the tissue called Xylem. The root hairs on the root absorb water from the soil and through osmosis the water is transported to leaves through the tissue xylem. |
