Hypotonic solution is the ones that have higher concentration of water as compared to the cells. When cells are placed in such solutions endosmosis occurs i.e. inward movement of water that causes swelling of cells and the RBCs burst easily because of being animal cells they lack cell wall, while the onion peel posses cell wall which makes it resistant to the bursting due to swelling cause by endosmosis.
