Which worm has feeding structures called hooks and suckers?
tapeworm
What is a scolex?
A scolex is the head region of a tapeworm, containing hooks and suckers that allow it to attach to the host's intestinal wall. It is essential for the tapeworm's survival and reproduction within the host's body.
What is the head of a tapeworm called and how is it used?
The head of a tapeworm is called a scolex. The tapeworm attaches itself to the intestine of the host with hooks and suckers that are on the scolex.
Is the knob-shaped head of a tapeworm containing hooks and suckers called a scolex?
Yes.
What is the holdfast of a tapeworm?
The holdfast of a tapeworm, also known as the scolex, is the specialized structure at the anterior end that enables the parasite to attach to the intestinal wall of its host. It typically features hooks and/or suckers, which facilitate a secure grip, allowing the tapeworm to avoid being dislodged by the host's digestive processes. This attachment is crucial for the tapeworm's survival and ability to absorb nutrients from the host's food.
How do tapeworms attach to the intestines?
A tapeworm lives in the intestines of its host, and survives by absorbing the partially broken down nutrients. A tapeworm has a head (scolex) that contains hooks that it uses to attach itself to the intestinal wall of the host.
What is the function of a scolex in tapeworms?
The scolex is the specialized head of a tapeworm that serves as an anchoring structure, allowing the parasite to attach securely to the intestinal wall of its host. It typically features hooks or suckers that facilitate this attachment, preventing the tapeworm from being dislodged during digestion. This anchoring is crucial for the tapeworm’s survival and ability to absorb nutrients from the host's digestive system.
How do tapeworms attach to their host?
They use the hooks and suckers on the anterior (head) part of their body.
Cestoda are ectoparasite or endoparasite?
Cestoda are endoparasites, which means they live inside their host's body, particularly in the digestive system. They have specialized adaptations for this lifestyle, such as their flat, ribbon-like body structure and hooks or suckers for attachment within the host's intestine.
Does tapeworm have appendages?
Tapeworms do not have appendages like legs or arms. Instead, they have a flat, ribbon-like body composed of segments called proglottids. They attach to the host's intestinal wall using specialized structures called scolex, which may have hooks or suckers, but these are not considered true appendages.
Why are hooks and suckers not typically found in organisms inhabiting water standing ecosystems?
because .
Morphology of taenia saginata?
Taenia saginata, also known as the beef tapeworm, is a parasitic flatworm that infects humans through the ingestion of raw or undercooked beef containing its larvae. The adult worm consists of a scolex (head) with hooks and suckers for attachment to the intestinal wall, followed by a long ribbon-like body called a strobila composed of multiple segments called proglottids. Each proglottid contains male and female reproductive organs for reproduction and can produce thousands of eggs that are passed in feces to continue the life cycle.
