Q.33
Given below are two statements
Statement (I) : The active absorption of water takes place due to the activity of root and root hairs.
Statement (II) : The rate of absorption depends upon transpiration in active absorption of water.
In light of the above statements, choose the most appropriate answer from the options given below.
- Statement (I) is True: Active absorption of water occurs through the metabolic and osmotic activity of root cortical and endodermal cells, generating root pressure ($0.1\text{ to }0.2\text{ MPa}$).
- Statement (II) is False: Active absorption operates independently of transpiration and is most prominent under low transpiration conditions (e.g., humid nights leading to guttation). Passive absorption, which accounts for $\gt 95\%$ of water uptake, is directly driven by the transpirational pull generated in leaves.
- Conclusion: Statement (I) is true but Statement (II) is false.
Correct option: (3) Statement (I) is true but Statement (II) is false.
