原生質絲(英語:Plasmodesmata)為植物細胞和部分藻類細胞壁間貫穿細胞壁的特有孔道,可以讓相鄰細胞的細胞質相互流通。有微小孔道,為細胞間物質運輸與信息傳遞的重要通道,通道中有一連接兩細胞內質網的連絲微管,細胞質可經由原生質絲交流及運輸,此過程稱為共質體運輸。 目前已知擁有原生質絲的包含植物界的所有物種,以及藻類中輪藻綱、輪藻目、褐藻綱和。 植物細胞擁有動物細胞所沒有的細胞壁,鄰近的細胞藉由薄板相互分隔。雖然細胞壁對於部分蛋白質及溶質具有穿透性,但原生質絲對於共質體內的胞內運輸更可以控制原生質流的流向以及穿透的物質。 原生質絲有分兩種:初生原生質絲(primary plasmodesmata)及次生原生質絲(secondary plasmodesmata)。初生原生質絲在細胞分裂期間出現,而次生原生質絲是真正溝通成熟植物細胞的通道。 動物也有類似的構造,允許動物細胞間的物質交流,包含間隙連接(gap junctions)和(membrane nanotubes)
