  2. How do roots help a plant survive? 1) They hold them in the ground  anchor them • Help keep plants from getting moved by wind and running water

  3. How do roots help a plant survive? 2) They draw up water and minerals from the soil

  4. How do roots help a plant survive? • 3) store food for the plant • Ex. sweet potatoes, sugar beets, carrots

  5. How are roots so strong? • The tip of a root is protected by a layer of tough cells called a root cap • Root cap: a thin covering made up of cells protecting the tip of the root as it grows into the soil

  6. Taproots versus Fibrous Roots

  7. What are the roots called that have an original roots and then more roots that branch out from the original root? • Taproots

  8. Fibrous roots: made up of only thin, hairy branching roots

  9. What are aerial roots? • Roots that never touch the ground • Take in moisture from the air

  16. Parts of a Leaf • Epidermis: outermost layer of a leaf • Cuticle: waxy coating of a leaf that helps water from leaving the leaf • Chloroplasts are in layers of the epidermis

  17. Chloroplasts: the green “food factories” of the plant. What do chloroplasts need to make food? • 1) Sunlight • 2) Water • 3) Minerals • 4) Carbon dioxide

  18. How does the air get into the leaf? • Through tiny pores on the bottom of a leaf called stomata

  19. What does “evaporation” mean? • Part of the water cycle --> when water moves from a liquid to a gas form

  20. Plants help with the evaporation process when water evaporates or turns from liquid to gas when it is released through their leaves. What is this process called? • Transpiration: when water evaporates from a plant’s leaves
