第八章 植物構造與生長 (Plant Structure and Growth). 植物科學研究所 陳益明 教授 2003.11.13. 一、 一般概述 (Introduction to modern plant biology). ( 一 ) 植物各器官或組織的構造與功能是不可分的。 一般將陸地上生長的植物分為五大類： (Table 29.1 及 Fig 29.1) 輪藻類 (Charophytes) 苔蘚 (Bryophytes) 蕨類 (Pteriophytes) 或無種子維管束植物 (seedless vascular plants)

Flowering Plants: Structure and Organization. Unit 10: Plants. Flowering plants usually have three vegetative organs: the roots, the stem and the leaves. The roots are part of the root system; the stem and leaves are part of the shoot system.

Parts of a Seed. Mature embryo: was formed by mitosis root tip, shoot tip, cotyledon(s) Seed coat: formed from maternal flower tissue, encloses embryo and endosperm to protect seed. Endosperm: surround embryo and provides nourishment

Secondary Growth. Secondary Growth. Two types of growth Primary growth: up and down. Generated by apical meristems. Form _________ tissues Secondary growth: growth in girth. Generated by lateral (secondary meristems). Form __________ tissues. All plants do primary growth

Plant Structures and Growth. By:Nhi and Gabriella. .The Plant Structure. The buds are at the tip of the stems. The root hairs are extensions of epidermal. The Tissue System. Tissue System • protection • prevention of water loss Epidermis Periderm

Growth is an irreversible increase in size. In plants, this is a function of cell division coupled with cell elongation. Growth in Plants. Primary growth elongates the axis of a plant. Secondary growth increases the girth of a plant. Meristems.

Plant Growth and Development. Flowering Plants are either Monocots or Dicots. Cotyledons provide nutrition for the plant’s early life. http://home.earthlink.net/~pj1place/dicot.jpg. Monocot seed Dicot seedling. cotyledons.

DEFINITIONS. Growth or grow means an increasing incident of volume which covers the increase of the number of cell, cell volume, kinds of cell and substances of cell that is irreversible.
