Question

For which purpose pharynx (a tube like extension) is used by planaria?

• A. Respiration
• B. Movement
• C. Intake of food
• D. Transportation

Answer 1

The correct option is C

Intake of food

Planaria eat living or dead small animals such that they suck up with their muscular mouth. Food passes from the mouth through the pharynx into the intestines where it is digested by the cells lining the intestine. Then its nutrients diffuse to the rest of the body. So the purpose of the Pharynx is to take the food in.
