Study Notes
Pathway of Water Absorbed by Roots
- Water enters root hairs, increasing concentration in root hair cells compared to cortex.
- Water moves from root hairs to cortical cells through osmosis, then reaches the xylem.
- Water is subsequently transported to the stem and leaves.
Types of Movement of Water into Root Cells
- Water absorption leads to movement deeper into root layers via two pathways: apoplast pathway and symplast pathway.
Apoplast Pathway
- Involves movement of water through intercellular spaces and cell walls.
- Does not require crossing cell membranes, allowing for faster movement.
- Dependent on the concentration gradient.
Symplast Pathway
- Water moves between adjacent cells through plasma membrane, cytoplasm, and plasmodesmata.
- This transport method is slower due to membrane crossing.
- Follows the concentration gradient, ensuring efficient water movement.
