Caecum is large for digestion of cellulose With the help of symbiotic bacteria in

Options

A. Man
B. Rabbit
C. Cat
D. Frog.

Answer

**Step-by-Step Solution:**

1. **Understanding the Cecum**: The cecum is a pouch connected to the junction of the small and large intestines. It plays a crucial role in the digestive process, especially in herbivores.

2. **Role of Symbiotic Bacteria**: In certain animals, the cecum houses symbiotic bacteria that help in the digestion of cellulose, a complex carbohydrate found in plant cell walls. These bacteria produce enzymes, such as cellulase, that break down cellulose into simpler sugars.

3. **Identifying the Correct Animal**: Among the options provided (man, rabbit, cat, frog), we need to identify which animal has a large cecum adapted for cellulose digestion.

4. **Analyzing Each Option**:
- **Man**: Humans are omnivores and do not rely heavily on cellulose digestion; thus, their cecum is not particularly large.
- **Rabbit**: Rabbits are herbivores and consume a high-fiber diet rich in cellulose. They have a large cecum that contains symbiotic bacteria to aid in cellulose digestion.
- **Cat**: Cats are obligate carnivores and do not have the necessary adaptations for cellulose digestion.
- **Frog**: Frogs are primarily carnivorous and do not have a large cecum for cellulose digestion.

5. **Conclusion**: The rabbit is the correct answer because it has a large cecum that facilitates the digestion of cellulose with the help of symbiotic bacteria.

**Final Answer**: Rabbit
