Answer Details
In the tapeworm, the suckers on the scolex are used for holding fast to the host. The scolex is the head of the tapeworm and contains the hooks and suckers that the parasite uses to attach itself to the lining of the host's intestine. Once attached, the tapeworm begins to grow and feed on the host's digested food.
The suckers on the scolex are like small suction cups that can create a vacuum-like seal against the host's intestinal wall. This allows the tapeworm to anchor itself securely in place and avoid being expelled from the host's body through peristalsis (the wave-like contractions of the intestines that move food through the digestive system).
So, in summary, the suckers on the scolex of a tapeworm are used for holding fast to the host's intestinal wall and avoiding expulsion from the body.
