Question

What is the function of diverticulum in the digestive system of planaria?

Answer 1

Planaria eat living or dead small animals that they suck up with their muscular mouths. Food passes from the mouth through the pharynx into the intestines where it is digested by the cells lining the intestines. Then its nutrients diffuse to the rest of the planaria.Planarians can have different pigmentation such a light brown, dark brown, black, or white. The characteristic planarian triangular head has two auricles and two light-sensing eye spots (ocelli) which give the worm a “cross-eyed” appearance. The auricles contain chemoreceptors that are used to find food.
