Membranes fulfill a variety of tasks in living cells: for example, they separate the cells from their surroundings and thus protect them. Also, by means of transport proteins they convey the necessary nutrients to the interior. Membranes are also instrumental when cells grow together to form tissue, when they proliferate by dividing, or when they move.
