1. roots

   Anmerkungen:

   • send water up to the plant through the xylem tubes
2. stems
   1. xylem

      Anmerkungen:

      • brings water up from the roots
   2. phloem

      Anmerkungen:

      • brings nutrients down from leaves
3. leaves

   Anmerkungen:

   • have stomata to let air and water in and out of the plant send nutrients to the plant through the phloem tubes
   1. needles

      Anmerkungen:

      • needles do not dry out as fast , so some plants keep their needles during the winter or during the dry seasons
      • don't have as many stomata as the leaves

Anmerkungen:

• response to stimuli
• maintain stability and balance

1. tropisms
   1. phototropism
   2. thigmotropism
   3. gravitropism

Anmerkungen:

• maintains balance
