\n H\u00fccreleri; canl\u0131, k\u00fc\u00e7\u00fck, ince \u00e7eperli, bol sitoplazmal\u0131, b\u00fcy\u00fck \u00e7ekirdekli ve \u00e7ok k\u00fc\u00e7\u00fck kofulludur.
\n H\u00fccreler aras\u0131 bo\u015fluklar yoktur. Meristem h\u00fccrelerinde mitoz b\u00f6l\u00fcnme h\u0131zl\u0131d\u0131r ve ayn\u0131 zamanda hormon \u00fcretirler.
\n 1. Birincil (Primer) Meristem
\n Bitkiyi meydana getiren ve bitkinin \u00f6mr\u00fc boyunca b\u00f6l\u00fcnme \u00f6zelli\u011fini kaybetmeyen meristeme denir. Primer meristem, y\u00fcksek yap\u0131l\u0131 bitkilerde k\u00f6k, g\u00f6vde ve dallarda yo\u011funla\u015fm\u0131\u015ft\u0131r. K\u00f6k ve g\u00f6vde u\u00e7lar\u0131ndaki bu b\u00f6lgelere b\u00fcy\u00fcme noktalar\u0131 denir.<\/p>\n
2. \u0130kincil (Sekonder) Meristem
\n De\u011fi\u015fmez doku h\u00fccrelerinin, hormonlar\u0131n da etkisiyle sonradan b\u00f6l\u00fcnme \u00f6zelli\u011fi kazanmas\u0131yla meydana gelen dokudur. \u0130kincil meristeme \u00f6rnek olarak, k\u00f6k ve g\u00f6vdenin enine b\u00fcy\u00fcmesini sa\u011flayan kambiyum ile mantar meristemi (fellojen) verilebilir.
