Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following would be least likely to affect osmosis in plants?
A
proton pumps in the membrane
B
a difference in solute concentrations
C
receptor proteins in the membrane
D
a difference in water potential
Explanation: 

Detailed explanation-1: -So the correct answer is ‘Gravitational potential’.

Detailed explanation-2: -So the correct answer is ‘Water passing from one xylem element to the other above it’.

Detailed explanation-3: -Osmosis helps in the absorption of water molecules from the soil by the root hairs. Osmosis maintains the turgidity of plant cells and therefore, maintains the structure of the plant parts. It also helps in water transport across the cells. The water molecules move between cells through a semipermeable membrane.

Detailed explanation-4: -The soil solution is usually very dilute. After fertilizing a lawn, the concentration of salts in the soil builds up.
