Mechanism of Absorption of Water | Plant Physiology

The absorption of water by the root hair does not depend solely upon its osmotic concentration but also upon its osmotic potential which is equivalent to the difference between its osmotic potential and its pressure potential. If the root hair becomes fully turgid, in order that its osmotic pressure becomes zero, it will absorb no more water from the soil. [...]

Active Water Absorption | Plant Physiology

Some instances water absorption appears to take place through the mediation of forces which originate in the root itself. Such a process is called active water absorption. It is operative in the form of root pressure, bleeding and guttation. Root Pressure: Roots of plants absorb water from the soil. Water thus absorbed is exuded in the dead xylem ducts of [...]
