  1. PLANTS Structure A. Roots 1. Anchor plant 2. Collect H2O and minerals 3. Phloem – carries food 4. Xylem – carries H2O and minerals (osmosis) 5. Root hairs – Increase surface area

  2. Tap Root Fibrous Roots Root Types Adventitious Root

  3. B. Stems 1. Transport food and H2O from roots to leaves. 2. Hold leaves up 3. Herbaceous – soft, green, flexible Woody – hard, strong, rigid 4. Cambium – layer of cells that divide to make new xylem and phloem

  4. Terminal Bud Stem Diagram Lenticels

  5. C. Leaves 1. Produce food for plant. 2. Stomates – on lower surface; allow H2O vapor to pass in and out of leaf (CO2 in, O2 out) 3. Mesophyll – middle layer; contains chloroplasts 4. Vein – bundle of xylem and phloem

  6. Leaf Diagram
