Nutrients and ions can pass directly from cell to cell through special membrane junctions known as ________.
A) desmosomes
B) gap (communicating) junctions

D) microvilli
E) tight junctions

Question

Quizplus · Accepted Answer

Gap junctions allow for direct communication and passage of nutrients and ions between cells. Desmosomes are involved in cell adhesion, tight junctions create a barrier to prevent the passage of molecules between cells, inclusions are nonliving structures such as pigments or glycogen, and microvilli increase surface area but do not directly allow for passage between cells.
