Understanding Hydra's Digestion and Excretion
Hydra, a freshwater cnidarian, has a unique method of digestion and excretion that is crucial for its survival.
Digestion Process
- Hydra captures food using its tentacles, which possess specialized cells called nematocysts that can sting and immobilize prey.
- The captured food is then ingested through the mouth into the gastrovascular cavity, where extracellular digestion occurs. Enzymes break down food particles into absorbable molecules.
Excretion of Waste Materials
- Once digestion is complete, the waste material, including undigested food and nitrogenous waste, must be expelled from the body.
- In Hydra, the mouth serves as the primary site for this process. Waste is eliminated through the same opening that is used for ingestion, making the mouth a crucial part of both feeding and excretion.
Role of Body Wall
- The body wall also plays a role in excretion. The gastrovascular cavity is lined with cells that can absorb nutrients and facilitate the removal of metabolic waste.
- While the tentacles help in capturing food, they do not directly participate in the excretion process.
Conclusion
Based on this understanding, the correct answer to the question is option 'A': waste material from food digestion and nitrogenous waste is removed from the mouth and body wall. This dual function of the mouth highlights the simplicity and efficiency of Hydra’s biological systems, allowing it to thrive in aquatic environments.
