ions can travel directly from the cytoplasm of one animal cell to the cytoplasm of an adjacent cell through
○ plasmodesmata.
○ gap junctions.
○ desmosomes.
○ tight junctions.
○ intermediate filaments.

Explanation:

Plasmodesmata are only present in plant cells, not animal cells. Desmosomes anchor adjacent animal cells together but do not allow ion passage between cytoplasms. Tight junctions seal cell gaps to prevent substance movement between cells. Intermediate filaments are structural components inside cells, not intercellular channels. Gap junctions are protein channels that connect the cytoplasms of adjacent animal cells, enabling direct ion and small molecule transfer.

Answer:

O gap junctions.
