A teacher described the structure and function of an organelle as follows:

This organelle is small and formed by the Golgi apparatus. It contains digestive enzymes that are responsible for splitting complex chemical compounds into simpler ones, such as when proteins are broken down into amino acids. Sometimes these organelles may destroy old or damaged cells.

Identify the type of organelle described by the teacher.

• Golgi body

• Lysosome

• Vacuole

• Centriole
