Describe how the tapeworm is adapted to a parasitic mode of life.
Answer:
-Has hooks/ suckers for attachment to wall of intestines.
-Long to increase surface area for absorption of food.
-Secretes enzyme/neutralize digestive enzymes (mucus inhibitor substance/ anti-enzymes)
-Hermaphroditic: to ensure reproductive/self-fertilization.
-Production of many eggs to ensure survival.
-Segment for egg dispersal
-More than one host for transmission e.g T solium- pig (intermediate host), T saginata.
- Long to fit in the intestine/ increase surface area for (flatten) absorption of food
- Anaerobes survive in the gut with low oxygen concentration.
