The plasma membrane of cells lining the small intestine has __________,which are specialized for absorption of nutrients.
A) flagella

E) dynein arms

Question

Quizplus · Accepted Answer

Microvilli are finger-like projections of the plasma membrane that greatly increase the surface area of cells, allowing for increased absorption of nutrients. Flagella are not found in the small intestine, and cilia are not as specialized for absorption as microvilli. A glycocalyx is a coating of carbohydrates on the plasma membrane that helps with cellular recognition and communication, but it is not specialized for absorption. Dynein arms are motor proteins found in cilia and flagella, but not in the small intestine.
