  1. Plants Unit Monday 09/10/2012

  2. Goal for the Day Review: Be able to list the major parts of plants and describe their functions. Be able to draw the phylogenetic tree of plants.

  3. Question of the Day What are the major parts of a plant? Do all plants have them?

  4. Question of the Day What are the major parts of a plant? Do all plants have them?

  5. Phylogenetic Tree of Plants • Shows the Evolutionary relationship between major plant groups. • That is it shows the _________ over • _______ between the major plant groups.

  6. Phylogenetic Tree of Plants TIME Non-vascular plants (they don’t have vascular tissue) TRUE ROOTS STEMS LEAVES Contain Vascular Tissue, so which groups of plants lack these?

  7. Phylogenetic Tree of Plants • Each Green Dash on the tree indicates that every plant group above that line has that characteristic, and every plant group below that line lacks that characteristic. • For example as you can see Liverworts, Hornworts, & Mosses all lack vascular tissue: They are non-vascular plants. However, Ferns, Gymnosperms & Angiosperms all have vascular tissue, and are therefore vascular plants.

  8. Roots Functions… Absorbing water Anchor the plant Store Food (vegetables: potatoes, carrots, etc)

  9. Roots Types…DRAW ME! Taproot – example: carrotFibrous root

  10. Leaves Functions… Photosynthesis – using light to make food Stomata - Holes in the underside of leaves, which regulate the water loss in transpiration

  11. Stems Functions… Some photosynthesis Support Transport of nutrients through the two Vascular Tissues 1. Phloem – carries food from the leaves to the roots (moves down) 2. Xylem – carries water from the roots to the leaves (moves up)

  12. What makes a fruit? • Look at the picture again, and try to decide what characteristics make a fruit.

  13. What makes a fruit? • Look at the picture again, and try to decide what characteristics make a fruit. • It contains seeds, and also it COMES FROM A FLOWER!!!

  14. Scientific Method of Fruits • Using what we learned today about plants write out the steps of the scientific method to answer the question: Is it a fruit? • For the test look up online to see if your hypothesis is correct. • Ex. IF it comes from a flower, THEN it is a fruit.

  15. Check on Germinating Seeds • Make Observations & RECORD them in your observation table. • Is it dry? • Did it change color? • Does it smell? • Make any measurements that seem applicable (i.e. size of crack in the seed)
