Students have asked these similar questions
(1)
a. The process responsible for absorption of water by root hair of plants is :
a. Osmosis
b. Active transport
C.
Diffusion
b. The reason for my answer is because :
a. Concentration of cell sap is lower than that of soil water
b. Concentration of cell sap is higher than that of soil water
C. Movement of water molecules spending energy, opposing to diffusion
d. Water concentration of soil particles is lower than that of root hair cells
Increasing the concentration of solutes increases osmotic potential, hence water potential decreases.
A. Agree, because presence of solutes increses osmotic pressure and thus osmotic potential.
C. Agree, because they just represent the same values.
D. Disagree, because it is the decrease in water pressure that decreases osmotic potential.
B. Disagree, because presence of solutes increases osmotic pressure which decreases osmotic potential.
Please answer the following multiple choice question:
A plant cell that contains a higher solute concentration than the solution that surrounds it
A. becomes plasmolyzed
B. lyses
C. becomes crenated
D. develops turgor pressure
