What is a fold of the cell membrane called?
Think it through first, then pick an option.
- a Villi
- b Lamellae
- c Microvilli
- d Neurilemma
Answer and explanation
Correct answer: c Microvilli
The folds of the cell membrane are called microvilli.
Why the other options are wrong
- a Villi: Villi are the finger-like parts of the intestinal wall; the book calls the folds of the cell membrane microvilli.
- b Lamellae: Lamellae is not the name for the folds of the cell membrane; the correct name is microvilli.
- d Neurilemma: Neurilemma is a sheath on nerve fibres, not a fold of the cell membrane.
