Plasmodesmata.
F
Actin filaments.
검증된 단계별 안내1
Understand the function of gap junctions: Gap junctions are specialized intercellular connections that facilitate the direct transfer of ions and small molecules between the cytoplasm of adjacent animal cells.
Differentiate between the options: Desmosomes, tight junctions, intermediate filaments, plasmodesmata, and actin filaments have distinct functions that do not involve direct cytoplasmic transfer of ions.
Desmosomes provide structural support by anchoring cells together, but do not allow ion transfer.
Tight junctions create a seal between cells to prevent leakage of extracellular fluid, not for ion transfer.
Plasmodesmata are channels between plant cells, not animal cells, for cytoplasmic exchange.
