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 Typhlosole is a longitudinal fold found in the intestine of earthworms, particularly in the typhlosole region. This fold increases the surface area of the intestine, thereby enhancing the absorption of nutrients from the ingested soil and organic matter.

• Option (B) refers to the function of other parts of the digestive system, such as the gizzard, which grinds soil particles.
• Option (C) mentions the grinding of decaying leaves, which is also part of the earthworm's digestion process but is carried out primarily by the gizzard, not the Typhlosole.
• Option (D) refers to the transportation of nutrients, which is related to the circulatory system of the earthworm, not the function of Typhlosole.

Thus, 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.
