Bio1152 Chapter 35 Plant Structure, Growth, and Development
  1. Plants, like multicellular animals, have         composed of different          , which are in turn composed of        .
  2. The basic organs of vascular plants are        ,        , and         , organized into a        system and a        system.

    • A root          the plant to soil, absorbs minerals and        , and often         organic nutrients.

    • A stem consists of alternating        , the points at which leaves are attached, and             .

    • The leaf consists of a flattened        and a stalk called a          .

      • Each leaf is composed of several tissues.

      • Many leaves have been modified to perform specialized functions.

  3. Most plants have three tissue systems:         ,           , and         .

    • The dermal tissue system consists of the            and is often covered with a waxy          .

    • The vascular tissue system transports materials within the plant.

    • Ground tissue includes cells specialized for functions such as          ,                 , and          .

  4.            are regions of cell growth.

    •         meristems are located at the tips of        and in the buds of shoots where          growth occurs to lengthen the plant.

    •          meristems add thickness to stems and roots of        plants through            growth.

    • Secondary growth occurs in the           cambium and       cambium of roots and stems.

    • The alternation of         and       wood give rise to growth rings in trunks.
