Cyst

• Some protozoa under certain conditions produce a protective form called a cyst.

Functions of cysts of protozoa.

• Cysts are produced to survive unfavorable conditions.
• It protects protozoa against adverse changes in the environment such as nutrient deficiency, adverse pH, and low oxygen levels.
• Cysts are sites for nuclear recognition and cell division.
• Amoeba loses water, becomes circular, and secret a cyst membrane that serves as a protective covering in unfavorable conditions.
