Plant unit: a study on plant classification, germination, pollination, transpiration, respiration, & photosynthesis

  1. 1. Classification & Processes
  2. 2. PLANTS: How are plants divided up? How are they related? How are they different? Nomenclature: (naming of species)
  3. 3. PLANTS Nonvascular Vascular Mosses Lichens NOT A PLANT: Fungi/ mushrooms SEEDS NO-SEEDS Angiosperms Gymnosperms Monocots Dicots Conifers NO-SEEDS Ferns Horsetails
  4. 4. <ul><li>Nonvascular plants (“lacking vessels”), short & delicate </li></ul><ul><li>Mosses </li></ul><ul><li>1. cling to damp soil, rocks, shady trees </li></ul><ul><li>2. are tiny plants (1-2 inches tall) </li></ul><ul><li>3. leaves are only 1-2 cells thick </li></ul><ul><li>4. anchored with rhizoids (hair-like fibers)-not roots. </li></ul><ul><li>5. seedless; grow from spores </li></ul><ul><li>a) lichens : grow on tree; looks like scales/shells </li></ul><ul><li>b) fungi/mushrooms : grow on the ground </li></ul>http://upload.wikimedia.org/wikipedia/commons/1/11/Green_tree_moss.jpg

  8. 8. B. SEEDLESS : do not have seeds; use spores to reproduce, grow tall & thick EXAMPLE: fern http://www.freefoto.com/images/9909/06/9909_06_6179---Fern_web.jpg?&k=Fern http://www.shadegarden.net/wp-content/uploads/2008/07/cinnamon-fern.jpg http://eatdrinkbetter.com/2008/05/05/lovin-fresh-fiddlehead-ferns/
  9. 9. SEEDS: GYMNOSPERMS ANGIOSPERMS Gymnosperms (naked seed); no flowers; oldest kind of seed plants, they like cold/dry climates, use sexual reproduction, produce seeds on female cones http://www.netstate.com/states/symb/flowers/images/pine_cone_tassel.jpg

  11. 11. <ul><li> Angiosperms (flowering) produce flowers, form the largests division in plant kingdom; live lots of places/climates </li></ul><ul><ul><li>form seeds inside their fruits </li></ul></ul><ul><ul><li>Use sexual reproduction/ pollination </li></ul></ul><ul><ul><li>Examples: fruits, vegetables, grains, most nuts </li></ul></ul><ul><ul><li>Have a seed leaf or COTYLEDONS (2 kinds) </li></ul></ul>Angiosperms MONOCOTS DICOTS
  12. 12. <ul><li>COTYLEDONS: </li></ul><ul><li>Monocots have one cotyledon, (corn, rice, wheat, grasses) </li></ul><ul><li>Dicots have 2 cotyledons (bean plant, roses, cacti) </li></ul>http://commons.wikimedia.org/wiki/File:Monocot_vs_dicot_crop_Pengo.jpg
  13. 13. Plant Parts: What are the parts of a plant? What are their jobs?
  14. 14. What parts do you know? What do they do for the plant? <ul><li>Parts of a plant: What are they for? </li></ul><ul><li>Seeds </li></ul><ul><li>Roots </li></ul><ul><li>Stem </li></ul><ul><li>Leaves </li></ul><ul><li>Flowers </li></ul><ul><li>Makes more of the plant (babies) </li></ul><ul><li>Takes in water, anchors it, stops erosion </li></ul><ul><li>Holds up plant, water up & down </li></ul><ul><li>Makes food for the plant, breathes </li></ul><ul><li>Attracts a pollinator to make a seed </li></ul>
  15. 16. Plant Life cycle
  16. 17. What do plants need to survive? water Air (carbon dioxide) Soil (minerals) sunlight
  17. 18. <ul><li>Important processes: </li></ul><ul><li>Germination process by which a seed sprouts </li></ul><ul><li>Pollination process of spreading pollen to fertilize a flower’s egg to make a seed </li></ul><ul><li>Transpiration leaves releasing water into the air </li></ul><ul><li>Respiration leaves releasing oxygen </li></ul><ul><li>Photosynthesis plants turn sunlight into food </li></ul>
