  • Biology Plant Free Response 1. Water diffuses into a plant through its root hairs and then travels into the parenchymal cells of the cortex along the symplast and the apoplast. Then the water moves to the endodermis where it freely passes into the vascular cylinder and into the xylem. Once the water is in the xylem it moves upward toward the leaves. Then the water diffuses from the roots where the water potential is the highest to the air spaces in the leaves where the water potential is the lowest. From the veins in the... 587 Words | 2 Pages

  • Science - Trasportation in Plants - 755 Words Plants need water for photosynthesis but they take in water through their roots so they need to transport the water up the stem to the leaves. Water is taken in by the root hairs because there is a higher water potential in the soil than in the root hairs. Then osmosis occurs to move the water from a cell with high concentration of water to a cell with low concentration through the permeable membrane. Once the water has moved down the concentration gradient it reaches a vessel called a xylem.... 755 Words | 2 Pages
