<P> The lysosomes also act as the waste disposal system of the cell by digesting unwanted materials in the cytoplasm , both from outside the cell and obsolete components inside the cell . Material from outside the cell is taken - up through endocytosis , while material from the inside of the cell is digested through autophagy . Their sizes can be very different -- the biggest ones can be more than 10 times bigger than the smallest ones . They were discovered and named by Belgian biologist Christian de Duve , who eventually received the Nobel Prize in Physiology or Medicine in 1974 . </P>
