补充资料：胞饮作用和胞吞作用
胞饮作用和胞吞作用
pinocy tosis and endocytosis
吸收膜外吸附的溶液或物质.例如大分子或分子的聚集体(moleeular aggregates)，如图所示。一般胞饮作用是指以这种方式吸收液体徽滴的过程，胞吞作用是指吸收大分子或分子聚集体的过程，但有时也用胞饮作用或胞吞作用泛指通过质膜内陷吸收膜外所吸附的物质的过程。通常这种过程在矿质养分吸附中的作用不大，但胞饮作用或胞吞作用为大分子的吸收提供了一种可能的机理。(饶立华)胞饮作用和胞吞作用(pinocy‘0515 and“n-docytosis)细胞外的液体徽滴或物质吸附在质腆上，通过质膜内陷形成小囊泡而被消化吸收的过程。电镜观察的资料证明植物根可以通过质膜内陷的方式 脆饮作用及胞吞作用示意图(a)质膜外吸附大分子及液滴，(b)质膜在吸附大分子及液滴的部位内陷.(c)质膜内陷部位形成的小t泡进入细胞质，(d)小续泡 膜溶解。其内含物转移到细胞质中
