Eukaryotes - Lysosomes

Description:

Lysosomes are vesicular structures of the cytoplasm which are involved in intra-cellular digestive activities. These are absent in prokaryotes but present in eukaryotic cells.

Lysosomes are formed by the process of packaging in the golgi apparatus.

The lysosomes contain hydrolytic enzymes (lipase, proteases).

Primary lysosomes have only digestive enzymes in inactive form and are also called storage granules.

Secondary lysosomes have digestive enzymes and ingested food. It is formed by the fusion of primary lysosomes and endosomes (with ingested food or micro-organisms).
