Using the term water potential, explain why the onions ; (i)gained mass when soaked in dilute solutions of sodium chloride (ii)lost mass when soaked in concentrated solutions of sodium chloride

Step-by-step answer

P Answered by PhD

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis. Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.

Biology

how do carbon dioxide and oxygen move in and out of a mesophyll cell? By which process- active transport, diffusion, respiration or transpiration?

Step-by-step answer

P Answered by PhD

Carbon dioxide with the help of diffusion reach the other cells in the leaf and the oxygen which is produced during the process of Photosynthesis is diffused out of the leaf. Hence, diffusion is the simple process by which gaseous exchange takes place.
