What are Suckers?

• A. Worm cast
• B. Bristles
• C. Cilia
• D. Suckers

Answer: (D)

Suckers are suction-cup attachments that organisms use to grip surfaces. They work by pressing a disc against a surface and creating a vacuum inside, which lets the animal cling securely as it moves or feeds. In many suction-capable creatures, such as leeches, these discs at the ends of the body serve as anchors for locomotion and for holding onto a host during feeding. This makes sense here because the term describes the actual attachment organs, unlike worm casts (excretions), bristles (setae), or cilia (tiny moving hairs used for locomotion or feeding).
