of glucose present in a litre of its solution has an osmotic pressure of

4.98 b a r

. If the osmotic pressure of the solution is

bars at the same temperature, what would be its concentration?

State whether True or False.

During the daytime, the guard cells begin photosynthesis and the glucose produced during the process increases the osmotic pressure which draws water from the adjoining cells due to endosmosis.
