Plants: Presentation One for Spaced Learning

  1. 1. PLANTS: A SPACED LEARNING LESSON1st Presentation – No paper or pencils!!By: Andrea Kirk
  2. 2. NONVASCULAR PLANTS
  3. 3. NONVASCULAR PLANTS Nonvascular: These plants lack vascular tissue totransport water and nutrients. They rely on simple diffusion to move water, and mustlive in a moist environment. Cannot grow very tall because they lack vasculartissue. Lack true roots, stems, or leaves. Some haveroot-like structures called rhizoids Includes Mosses, Liverworts, and Hornworts
  4. 4. NONVASCULAR PLANTS
  5. 5. NONVASCULAR PLANTS Life Cycle: The gametophyte is the dominant generation Does not utilize seeds, but uses wind blownspores to disperse the offspring. Flagellated sperm requires water to reach andfertilize the egg; another reason why they mustlive in a moist area.
  6. 6. SEEDLESS VASCULAR PLANTS
  7. 7. VASCULAR PLANTS
  8. 8. VASCULAR PLANTS Vascular plants have specialized structures: Roots, stems, and leaves Differentiated tissues: meristematic, ground,vascular, and dermal tissues. Can grow much taller than nonvascular plants dueto their vascular structures. The life cycle has a dominant sporophytegeneration, in contrast to the dominantgametophyte in nonvascular plants
  9. 9. TISSUES Vascular plants have differentiated tissues thatperform separate but important functions. Meristematic Tissue: consists of cells that grow anddivide repeatedly. Vascular Tissue: these cells form the xylem andphloem that transport water and nutrients Ground Tissue: has cells that are rich in chloroplastsand conducts photosynthesis Dermal Tissue: these cells protect the vascularstructures of the plant.
  10. 10. TISSUES IN VARIOUS PLANT PARTS
  11. 11. MAIN PLANT PARTS Roots Stems Leaves All of these parts contain dermal vascular and groundtissues.
  12. 12. THE ROOTS Functions: Anchoring Absorption Storage Structure: Root Hairs – increase the surface area for moreabsorption Zone of Elongation Meristematic Zone – part of the root tip where cellsgrow and divide to extend the root. Root Cap – protects the root tip
  13. 13. STRUCTURE
  14. 14. STEM Function: Connects the roots to the leaves andacts as the plumbing for the plant Structure: Xylem: One way Transports water and minerals upward Stiff, thick walls Phloem Two way Transports products of photosynthesis and water up and down Perforated walls
  15. 15. STRUCTURE
  16. 16. STRUCTURE
  17. 17. LEAVES Function: Capture the sunlight and are the mainarea of photosynthesis for the plant. Structure: Leaf Margins:
  18. 18. LEAVES Leaf Types
  19. 19. LEAF STRUCTURE Cuticle – waxy and water repellent. Excreted bythe epidermis Epidermis - outer layer of cells Palisade Mesophyll – elongated cells that containa lot of chlorophyll Spongy Mesophyll – Round irregular cells thatallow for gas exchange Stoma – opening in the leaves for water and gasmovement (more on the bottom of leaf) Guard Cells – “Guard” the stoma to open andclose it. Vein – contains the xylem and phloem for the leaf.
  20. 20. LEAF STRUCTURE
  21. 21. PHOTOSYNTHESISReactants Products
  22. 22. TYPES OF VASCULAR PLANTS Seed: Gymnosperms Angiosperms Seedless: Ferns Whisk ferns Horsetails
  23. 23. SEED VASCULAR PLANTS Gymnosperms: Ginkgos, Gnetales, cycads, and conifers “naked seeds” that are not enclosed in aprotective structure. The ovule normally developson the surface of a scale (cone) or at the tip of amodified leaf. Conifers are the most abundant gymnospermsand include pine trees Life Cycle: The Sporophyte is the dominantportion of the life cycle.
  24. 24. GYMNOSPERMSGinkgoConiferGnetalesCycad
  25. 25. SEED VASCULAR PLANTS  Gymnosperms:
  26. 26. SEED VASCULAR PLANTSAngiosperms The most diverse group of land plants. “Flowering plants” - the ovule developsinside a protective ovary. The matureovary becomes a fruit. Life Cycle: The sporophyte is dominant.Double fertilization occurs to produce anendosperm, the food supply, and azygote.
  27. 27. SEED VASCULAR PLANTS  Angiosperms
  28. 28. SEED VASCULAR PLANTS Angiosperms Two main divisions of flowering plants. Monocotyledon: Monocots One cotyledon (seed leaf) Flower parts in threes Parallel leaf veins Scattered vascular bundles Dicotyledon: Dicots Two cotyledons Flower parts in fours and fives Net-like leaf veins Vascular bundles are arranged in a ring.
  29. 29. SEED VASCULAR PLANTS Seed structure
  30. 30. SEEDLESS VASCULAR PLANTS Include whisk ferns, ferns, club mosses,and horsetails. Life Cycle: The sporophyte is dominant Use windblown spores, not seeds, to dispersetheir offspring. The sperm is flagellated and requires water toreach the egg. These plants are limited to moist areas
  31. 31. SEEDLESS VASCULAR PLANTS
  32. 32. SEEDLESS VASCULAR PLANTS Sorus = cluster of sporangia that can be located onthe underside of a fern leaf. Sporangia = enclosure of spores
  33. 33. SEEDLESS VASCULAR PLANTS: FERN Fiddlehead:An uncurling frond
  34. 34. BRAIN BREAK Stretch! 2 minutes Push-up/sit-ups Grab a partner Do as many push ups or sit ups as you can while yourpartner counts for you 4 minutes Switch and count your partners push ups and sit ups! 4 minutes
