dexar [7]

A lysosome is a membrane-bound sac found in cells that contains digestive enzymes which break down complex molecules or structure.

Lysosomes are single membrane organelles or vesicles  that  contain enzymes and are  specialized to breakdown complex food materials  such as sugars and proteins, into simpler substances.

Lysosomes are made in a process that begins in the endoplasmic reticulum and ends in the Golgi apparatus which puts the finishing touches to the lysosome before releasing it into the cytoplasm where it floats freely until engaged.
