Lesson 8 - Plant Organization and Homeostasis

Introduction
 
"This lesson introduces the organs of a plantby first discussing the shoot system, composed of stems and leaves, and then the root system, which lies beneath the surface. The anatomy of the two main groups of flowering plants,monocots and eudicots, can becontrasted in several different ways. Monocots and the smaller group, but they perform vital services for humans. The levels of biological organization apply to plants, for example, several cells from a tissue, and several tissues make up an organ. In this this lesson, we examine plant cells and tissues, and how they are arranged in the organs of a plant."
 
Getting Started "The prevention of water loss is critical for palnts. The epidermis and the cuticle it produces help prevent water loss and overheating in sunlight. Gas exchange in leaves depends on the prescence of stomata, which close when plants are water stressed. In plants, the roots absorb water and have special extensions called root hairs that facilitate water uptake. Xylem transports water to all plant parts, including the leaves."
