Ions can travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell through
A) plasmodesmata.
B) intermediate filaments.
C) tight junctions.
D) desmosomes.
E) gap junctions.

Question

Quizplus · Accepted Answer

Gap junctions are specialized intercellular junctions that allow the direct passage of ions and small molecules between adjacent cells. These junctions are made up of proteins called connexins that form channels between the cytoplasm of two cells, allowing the movement of ions and small molecules. Plasmodesmata only exist in plant cells, intermediate filaments provide mechanical strength and support to cells, tight junctions prevent the movement of molecules between cells, and desmosomes provide mechanical strength to cells by connecting them through intermediate filaments.
