Epithelial cells of the intestine involved in food absorption have on their surface

Step-by-step solution

The mucosa and sub-mucosa of small intestine are thrown into folds. Surfaces of these folds is covered by fine, fingerlike projections of the epithelium. These projections are called villi. In addition, the epithelial cells of the villi are covered on their exposed surface by cytoplasmic projections called microvilli.
