Answer 1

Answer:

Flatworms have a head at one end with two eye spots. While flatworms cannot see like we can, they do recognize and respond to changes in light. They have two nerve cords running down each side of the body and triggering muscles to react to stimuli.

Answer 2

Planaria are the flatworms with simple eye.

Explanation:

• It's a flatworm with very basic 'eyes' that are really just light-detecting eye-spots.
• Planarians are another name for flatworms.
• They are members of the Platyhelminthes phylum.
• They have flat bodies, no backbone, and no circulatory or respiratory organs, among other characteristics.
• A pigmented cell cup and photoreceptor cells with rhabdomeres extending into the eye cup make up the planarian eye.
• The axons of these photoreceptors project straight to the planarian brain's visual centre.
