Biology Question on Transport in Plants
In potato osmometer, which of the following process is involved?
A
Physical process
B
Ohysiological process
C
Chemical process
D
Physico-chemical process
Answer
Physico-chemical process
Explanation
Solution
In potato osmometer, the potato scoop is filled with sugar solution and is kept in a beaker containing water. Now, due to osmosis which is the net movement of water molecules from a region of their higher concentration to a region where their concentration is low through a differentially permeable membrane, water comes inside the potato. Since a chemical gradient is developed along which there is physical movement of water, it is a physico- chemical process.
