Question

The function of Typhlosole in earthworm is

• A. Increasing the effective area of absorption in the intestine
• B. Grinding of soil particles
• C. Grinding of decaying leaves
• D. Transportation

Answer 1

The Correct Option is A

The correct answer is (A) : Increasing the effective area of absorption in the intestine.

Answer 2

The correct answer is: (A) Increasing the effective area of absorption in the intestine.

The typhlosole is a longitudinal fold present in the inner wall of the intestine of an earthworm. Its primary function is to increase the surface area available for absorption of nutrients. This structural feature enhances the efficiency of digestion and absorption by providing a larger surface area for nutrient uptake.

As the earthworm consumes organic material from the soil, the nutrients need to be absorbed efficiently in the digestive tract. The presence of the typhlosole helps achieve this by creating more surface area for the digestive enzymes to act upon the food particles, ensuring that the earthworm can absorb the maximum amount of nutrients from the digested material.

Thus, the typhlosole plays a crucial role in the digestive system of earthworms by increasing the effective area of absorption in the intestine.
