Presentation Transcript

  1. Mon April 21 To Do Today • Check seeds - draw, label and water • Complete Plant dissetion Activity Warm Up- • What does the term non-vascular mean? • How do non vascular plants get nutrients? Homework: progress reports Friday

  2. Seed Check • Examine your seeds - what can you label? Draw seeds (detail) and put into soil –being careful to no damage roots

  3. 35

  4. Parts of a Flower Lab Activity*handout

  5. Apples

  6. Tues April 22 To Do Today • Check seeds - draw, label and water • Foldable notes on angiosperms • Complete Plant dissetion Activity Warm Up- What is the name of The male part of flower? What parts does it contain? Homework: progress reports Friday

  7. Male parts of flower

  8. ANGIOSPERMS: • Have flowers • Fruits contain seeds with covering • Angiosperms are divided into two groups: Monocots & Dicots.

  9. Monocots • Parallel venation in leaves • Flower parts in multiples of 3 • Vascular tissue scattered in cross section of stem 24

  10. Dicots • Net venation in leaves • Flower parts in multiples of 4 or 5 • Vascular tissue in rings in cross section of stem 25

  11. April 24&25 To Do Today • Check seeds - draw, label and water • Foldable notes on angiosperms • Complete Plant dissection Activity • Review video on plants(handout) • Leaf Activity Warm Up- + reflection Homework:

  12. Cotyledons

  13. Is this a monocot or a dicot? Why? DICOT 2 leaves

  14. Non-essential parts- Not needed for sexual reproduction • Receptacle: Base of the flower • Sepals: smaller leaves protecting flower located at the base • Petals: Colored tissue covering the internal sexual organs • WHY ARE THEY SO BRIGHTLY COLORED???

  15. Pollination • Flower parts fall off and each Ovary grows into a fruit which contains seeds. • This only happens for plants that produce fruit

  16. To attract the pollinators….birds, bees, butterflies. • The goal of the plant is to get any pollinator to knock the pollen off of the stamen and have it land at the stigma. • Wind, rain or brushing up against a flower could also achieve this goal.

  17. Seed dispersal • Wind • Water • Animals

  18. Wed/Thurs/Fri • To Do Today • Review flowers • Finish notes on flowers in foldable • Coloring of leaves • Warm Up – reflection • 1. What are the 2categories of seed producing vascular plants? • 2. What is the function of the ovary of a flower? • Homework: none

  19. 1. 2.

  20. Other types of flowers • Some flowers, such as grasses, do not have brightly colored petals and nectar to attract insects. • These flowers are pollinated by the wind.

  21. Vascular System • Xylem tissue carries water and minerals upward from the roots • Phloem tissue carries sugars made by photosynthesis from the leaves to where they will be stored or used • Sap is the fluid carried inside the xylem or phloem Copy onto leaf anatomy handout 12

  22. Coloring of leaf anatomy Bill Nye: Plants video http://www.youtube.com/watch?v=VH3IFUDkGt8

  23. Parts of a Flower

  24. Some drinks from plants • Birch sap can also be used as an ingredient in food or drinks, such as birch beer or wintergreen flavored candy • Maple syrup is a syrup usually made from the xylem sap of sugar maple, red maple, or black maple trees, although it can also be made from other maple species. In cold climates, these trees store starch in their trunks and roots before the winter; the starch is then converted to sugar that rises in the sap in the spring. Maple trees can be tapped by boring holes into their trunks and collecting the exuded sap. The sap is processed by heating to evaporate much of the water, leaving the concentrated syrup • Root beer is a carbonated, sweetened beverage, originally made using the root of a sassafras plant (or the bark of a sassafras tree) as the primary flavor.

  25. Birch Trees Sap http://drinks.seriouseats.com/2011/03/best-birch-beer-taste-test-boylans-pennsylvania-dutch-kutztown-sioux-city-aj-stephans.html?ref=tastetest

  26. Plant Uses • Agriculture • Medicines • Clothing • Dyes • Building materials • Fuels 26

  27. Why We Can’t do Without Plants! • Produce oxygen for the atmosphere • Produce lumber for building • Provide homes and food for many organisms • Prevent erosion • Used for food 27

  28. More Reasons We Can’t do Without Plants! • Produce wood pulp for paper products • Source of many medicines • Ornamental and shade for yards • Fibers such as cotton for fabric • Dyes 28

  29. Medicines Clothing Agriculture Uses of Plants

  30. Building materials Fuels Dyes Uses of Plants
