what is endosmosis and exosmosis
Preetha was observing live cells of Onion in the Biology laboratory and she observed cell wall, cytoplasm and nucleus clearly. Suddenly her friend who was doing chemistry experiment spilled a few drops of salt water on the slide. After some time Preetha observed the slide and found some changes. (a) What would have been the change in the live cells of onion peel after adding salt water ?
