Question

Please help me I do not understand. Thank you!

In your own words how does water move from roots to shoots? Discuss the three mechanisms.

Answer 1

Transport is done by xylem and phloem

Phloem tissues carry food up from leaf Food made by the leaf Evaporation of water from leaves (Transpiration) Stem- Water and minerals from the soil Leaf Xylem tissues carry water and dissolved minerals up from roots Phloem tissues carry food down from leaf Roots Soil

plant absorbs water and minerals from soil through roots and transport it other parts like stem, leaves, flowers etc. It is through two kinds of elements of xylem

Water and minerals enter root hair-->then goes to xylem vessels--->leaves of plants

The food which is prepared by the process of photosynthesis in the leaves of a plant has to be transported to other parts like stem, roots, branches etc. Therefore this food is transported to other parts of the plant through a kind of tubes called phloem.
1-Water is passively transported into the roots and then into the xylem.
2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem.
3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.
