Does lysosomes use chemicals to break down food and worn out cell parts?

Simple Diffusion. In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane. It basically uses chemicals to break down fod and worn out cell parts to answer you question :)

Idon't know how to do this but maybe ask your mom or dad
