  1. Plants

  2. AngiospermsFlowering Plants

  3. Roots • Function: • Anchor • Absorb water & nutrients from soil • Types: • Tap root • Fibrous root

  4. Cross section of root with root hair. Absorption takes place through root hair

  5. STEMS • Function: • Hold plant upright • Transport water from roots to leaves • Transport sugar from leaves to roots

  6. Leaves • Function: • Capture light energy • Convert light energy to chemical energy • Make glucose, fructose, galactose

  7. STOMATA – opens & closes for gas exchange. Underside of leaf

  8. Flowers • Function: • Reproduction • Male: sperm (pollen) production • Female: egg/ovum (seed) production • Ovary becomes the fruit to protect egg (seed)

  9. Adaptations

  10. Bark adaptations Green bark in desert Thin peeling bark in rain forest

  11. Lianas The suction exerted by the leafy crown to draw up all this water from the roots is powerful. If a small cut is made in a liana stem, a hissing sound can be heard as air is sucked into the severed vessels. Lianas do not twine around the trunks of their supporting trees. Their stems hang freely, their weight carried by many small attachments in the crown.

  12. Leaf drip tips

  13. Rain forest leaves

  14. Adaptations Cypress knees help exchange gases buttresses

  15. Prop roots

  16. Epiphytes

  17. Bromeliads

  18. Mangroves

  19. Black Mangrove – “fingers” extrude salt Mangrove
