维管束的原声例句

维管束的网络释义

维管束 维管束是指维管植物（包括蕨类植物、裸子植物和被子植物）的维管组织，由木质部和韧皮部成束状排列形成的结构。维管束多存在于茎（草本植物和木本植物幼体）、叶（叶中的维管束又称为叶脉）等器官中。维管束相互连接构成维管系统，主要作用是为植物体输导水分、无机盐和有机养料等，也有支持植物体的作用。 维管束彼此交织连接，构成初生植物体来输导水分，无机盐及有机物质的一种输导系统——维管系统，并兼有支持植物体的作用。 在维管束的发育过程中，初生木质部和初生韧皮部还可分为发育较早的原生木质部和原生韧皮部，以及发育较迟的后生木质部和后生韧皮部。由于早先发育的原生木质部和原生韧皮部分子，在初生植物体伸长生长时就已成熟，它们不再与周围的细胞一起继续伸长，因而常被挤毁，或留下原生木质部的腔隙，如玉米的茎中的维管束。 在维管束的周围，通常由一层或数层具支持作用的厚壁组织细胞组成的维管束鞘所包围。它们有时仅在木质部或韧皮部的一端，或同时出现在两端。
