can you describe the pathway followed by water molecules in plants?

Question

describe the pathway followed by water molecule from the time it enters a plant root to the time it escapes into the atmosphere from a leaf.
need ur help asap! thanks a bunch!! :D

Answer 1

root hairs --- vacuole or cytoplasm of root hairs ---- epiblema --- cortex ---- passage cell of endodermis ----- protoxylem ----- metaxylem ------ xylem trachieds ------ upward movement of sap-----

the sap then moves to specific areas. eg: xylem cells ---- leaf petiole ---- mesophyll cells of leaves ---- stomata present on the leaf epidermis ---- atmosphere.

Answer 2

THe pathway noted above by rahul seems reasonable. Most of the water taken in by a plant follows this pathway. But plants also use water for photosynthesis: When light strikes a leaf ,the chlorophyll (a green pigment found in chloroplasts) becomes chemically "excited", or energized. It uses this energy to break down (photolysis) the water molecule (H2O) into H2 and O2. The O2 (molecular oxygen) exits the leaf via the stomates, and goes into the atmosphere.
The H (hydrogen) atoms , by way of many complicated chemical pathways (like the Calvin cycle), combines with Carbon dioxide to manufacture food (like PGAL /glucose).
