  1. Plant Classification PLANTS!

  2. Nonvascular Plants Characteristics: Live in MOIST environments WHY? Absorb WATER and NUTRIENTS from their environment NO vascular tissue! (thin cell walls)

  3. Nonvascular: MOSSES

  4. Nonvascular Plants Examples: Mosses Gametophyte is green and fuzzy Sporophyte is long and slender with capsule at the end Peat moss is used in agriculture and gardening Peat is used as fuel

  5. Nonvascular: Liverworts

  6. Nonvascular Plants Liverworts Found on Moist Rock and Soil beside streams

  7. Nonvascular: Hornworts

  8. Nonvascular Plants Examples: Hornworts Found in Moist Soils

  9. Nonvascular PlantsA Moss Plant (Pg. 123) Drawing: Label: Sporophyte Capsule Stalk Gametophyte Stemlike structure Leaflike structure Rhizoids

  10. Sphagnum Moss turns to Peat

  11. Vascular Seedless Plants Characteristics: Have vascular tissue- system of tubelike structures inside a plant that water, minerals, and food move through Do NOT produce seed-reproduce with spores Live in moist surroundings so sperm can swim to eggs

  12. Seedless Vascular Plants Examples: Ferns Size range is small to 5 meters tall! Fronds are FERN LEAVES

  13. Club Mosses How are club mosses different from “true” mosses?

  14. Seedless Vascular Plants Examples: Club Mosses Grow on moist woodlands near streams

  15. Horsetails

  16. Seedless Vascular Plants Examples: Horsetails Steams are jointed

  17. Seedless Vascular PlantsFERN: Page 128 Drawing: Label: Frond Spores Stem Roots

  18. Spores on a Fern Frond

  19. Ticket Out the Door On a piece of paper draw the Venn Diagram below. Include: 2 Similarities between Nonvascular and Seedless Vascular Plants 2 Differences between Nonvascular and Seedless Vascular Plants Nonvascular Seedless Vascular 1. 1. 1. 2. 2. 2.

  20. Gymnosperms Characteristics: Seed plant that produce Naked Seeds Have needle-like or scale-like leaves and deep growing roots

  21. Gymnosperms Examples: Cycads- palm trees with cones Conifers- Cone bearing plants; aka Evergreens because they keep their leaves year-round Ginkgoes- Ginkgo biloba Gnetophytes- live in hot desert and tropical rainforest

  22. Cycads Look like Palm trees with cones

  23. Conifers Cone Bearing Plants Evergreens (keep leaves year-round)

  24. Ginkgoes Only ONE species: Ginkgo biloba

  25. Gnetophytes Live in hot deserts and tropical rainforests

  26. Gymnosperm Life Cycle Use POLLEN and SEEDS to reproduce!

  27. Seeds- 3 main parts

  28. Seed Dispersal The scattering of seeds so they are away from the parent plant.

  29. Seed Dispersal Video What are some ways that seeds are dispersed? What are the 3 parts of a seed?

  30. Angiosperms Characteristics: Produce flowers Seeds are enclosed in fruits

  31. Angiosperms Characteristics: FLOWER Reproductive structure of an angiosperm

  32. Angiosperms Characteristics: FRUIT Ripened ovary and other structures that enclose one or more seeds http://www.youtube.com/watch?v=sEwmUbzN_-g (Fruit Development) Dandelion (http://www.youtube.com/watch?v=UQ_QqtXoyQw)

  33. Angiosperms

  34. Monocots vs. Dicots

  35. Angiosperms- MONOCOTS Tulips Grass Wheat Corn

  36. Angiosperms- DICOTS Roses Violets Dandelions

  37. Pollination http://www.ted.com/talks/louie_schwartzberg_the_hidden_beauty_of_pollination.html

  38. Angiosperm Life Cycle

  39. Drawings POLLEN OVARY (Label OVULE) • 100x
