1.	Which of the following statement are not true? (a) In CAM plants, stomata open during dark and remain closed during the day. (b) Role of `Na^(+)` in stomatal opening is now universally accepted. (c) Water potential of root cells is higher than water potential of soil. (d) Capillarity theory most accepted theory of water movement through plants. (e) Wall of xylem vessels made up of lignocelluloes has strong affinity for water molecules.A. b,c and eB. b,c and dC. a, b and cD. b and c
Answer» Correct Answer - B In CAM plants, stomata open during dark and remain closed during the day. Role of `K^(+)` in stomatal opening is now universally accepted. Water potential of root cells is lower than water potential of soil. Cohesion-tension transpiration pull model is most accepted theory of water movement through plants. Wall of xylem vessels made up of lignocellulose has strong affinity for water molecules.
