Question

Quizplus · Accepted Answer

Planarians scrape and suck food particles through a midventral proboscis, located on the ventral surface of the animal. They do not attach with a sucker to extract blood (A), or engulf food particles through an anterior mouth and excrete waste via an anus (C). The planarian's epidermal surface is thin and does not allow it to soak in nutrients (D). Although the flame cell system is responsible for excretion, itis not involved in nutrient uptake (E).
