Detailed Solution
Download Solution PDFThe correct answer is rumen.
Key Points
- In ruminants like cattle, bacteria present in the rumen (the largest compartment of the stomach) play a crucial role in the digestion of cellulose.
- The rumen is a fermentation chamber where complex carbohydrates, such as cellulose from plant material, are broken down by microbial fermentation.
- Bacteria in the rumen possess cellulolytic enzymes that break down cellulose into simpler forms that can be further digested and utilized by the ruminant host.
- This symbiotic relationship between ruminants and rumen bacteria allows them to efficiently extract nutrients from plant-based diets.
