Transpiration and root pressure cause water to rise in plants by (a) pushing it upward (b) pushing and pulling it, respectively (c) pulling it upward (d) pulling and pushing it, respectively.
Option D The transpiration process, pulls water upwards with the help of cohesion and adhesion properties of water molecules. According to transpiration pull theory, due to transpiration, the water column inside the plant comes under tension. This is called ‘transpiration pull’. On account of this tension, the water column is pulled up passively from below to top of the plant (almost like a rope). Root pressure is the pressure that forces water, absorbed
