Lecture #2 Plant Anatomy and Transport

I. Plant Cells and Tissues

II. Three kinds of Tissues

  1. Epidermis
    1. Outer covering
    2. Gas exchange
  2. Vascular-Transport of water and dissolved substances (sugar)
    1. Xylem- Up from the roots
    2. Phloem- Down from the leaves
  3. Ground- the rest of the plant
    1. Leaf- mesophyll and vascular
    2. Stem- Pith, cortex and vascular
    3. Root- cortex and vascular
  4. Main purpose is to get and keep water

III. Plant organs- groups of tissues

  1. Roots
    1. Anchorage, Absorption, Storage, Conduction
    2. Structure
  2. Stems
    1. Support
    2. Structure
  3. Leaves
    1. Photosynthesis
    2. Structure

IV. Transport

  1. Water and minerals
    1. Transpiration, Adhesion, Cohesion
  2. Sugar
