Lysosomes are the organelles in charge of digesting and breaking down all matter in a cell that needs to be broken down, varying from food and energy molecules to viruses and bacteria.
If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn't even have to become extinct to affect one of its predators.
i think the answer is because the cell membrane acts as a protecter for cells. It also moves liquds and since it does move liquids it wouldn't desolve from it.
