Water movement in leaf? |
| Answer» Water\xa0is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the\xa0water\xa0molecules to form a column in the xylem. 3-\xa0Water moves\xa0from the xylem into the mesophyll cells, evaporates from their surfaces and\xa0leaves\xa0the plant by diffusion\xa0through\xa0the stomata.\xa0Osmosis is the\xa0movement of water\xa0across membranes that allow\xa0water\xa0to move freely but that control the\xa0movement\xa0of dissolved substances, such as mineral ions. | |
