Explanation:
Assertion (A): The inner lining of intestine has tall epithelial cells.
Reason (R): Columnar epithelium facilitates absorption and secretion.
The correct answer is option A, which states that both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation of Assertion (A):
The inner lining of the intestine has tall epithelial cells. These cells are called columnar epithelial cells. They are long and narrow, and they are arranged in a single layer. The columnar epithelium is found in the inner lining of the intestine because it facilitates absorption and secretion. The columnar epithelium has a large surface area, which helps in the absorption of nutrients from the food that passes through the intestine. It also secretes mucus, which protects the inner lining of the intestine from harmful substances that may be present in the food.
Explanation of Reason (R):
Columnar epithelium facilitates absorption and secretion. The columnar epithelium has a large surface area, which helps in the absorption of nutrients from the food that passes through the intestine. It also secretes mucus, which protects the inner lining of the intestine from harmful substances that may be present in the food. The tall epithelial cells of the columnar epithelium are specialized for absorption and secretion, as they have a large number of microvilli on their surface, which increases their surface area further and facilitates the absorption of nutrients.
Conclusion:
Thus, both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A). The inner lining of the intestine has tall epithelial cells, which are specialized for absorption and secretion, and the columnar epithelium facilitates this process.
