1. Plants!!! What Domain? What kingdom? Eukaryotic or Prokaryotic? Autotroph or Heterotroph? Multicellular or Unicellular?

2. What do you notice about each of these plants. What kind of environment do you think they may live in?

3. What is a vascular plant?  They have vascular tissue = a transport system  Main organs: They all have roots, stems, and leaves !  Think back to that big tree. Plants are living. Just like you, they need water and food to survive. A plant that tall needs a way for water and food to reach all parts of it! = a need for a transport system! Add to your notes!

4. Root System: fibrous vs. taproot  Fibrous – many tiny roots - Help prevent soil erosion  Taproot - one main root Ex. carrots Add to your notes! Function: to absorb water/nutrients, anchoring/support

5. Stems : Function: transport Transport system= vascular bundle 1) Xylem – transports water from roots to the leaves (up) 2) Phloem – transports food in both directions (up and down)

6. Leaves: Simple vs. Compound Simple leaves only have 1 blade Compound leaves has many small leaves Function: site of photosynthesis

7. What you don’t see… Mesophyll (middle layer); have a lot of chloroplasts

8. Stomata and Guard Cells  Stomata : small openings in the leaf that allow gas exchange and water to pass through  Guard cells - two cells that form stomata

9. Chloroplasts!

10. Questions we should be able to answer.. 1) What are the three organs of a vascular plant? 2) What is xylem? What is phloem? 3) What are the two kind of root systems? 4) What is the difference between a simple and compound leaf? 5) What is the stomata? What controls the opening and closing? 6) What is a cuticle?

11. Non-Vascular = does not have a transport system

12. Ex. ferns Ex. pine trees, apples trees Ex. mosses, liverworts, hornworts

13. Stomata ( opening ) Guard Cells (control stomata) Phloem ( transports food ) Xylem ( transports water ) Vascular Bundle (encloses xylem and phloem ) Cuticle (waxy covering to reduce water loss) Mesophyll (middle layer)
