Transcript of "Introduction to Plants - Basic Overview"

  1. 1. 14.0 Describe Principles of Plant Growth Production 14.2 Explore methods of classifying plants. Introduction To Plants
  2. 2. Two Groups of Plants <ul><li>Nonvascular - most primitive, rely on water coming to them. </li></ul><ul><li>Vascular - contain vascular tissue that transports water. </li></ul><ul><li>And Fungi – which are not plants </li></ul>
  3. 3. And Non Plants <ul><li>Fungi - </li></ul><ul><ul><li>most primitive; do not have </li></ul></ul><ul><ul><li> true roots, leaves, </li></ul></ul><ul><ul><li>stems </li></ul></ul><ul><ul><li>do not contain chlorophyll in their cells </li></ul></ul><ul><ul><li>Obtain their food from other sources – heterotrophs or parasites </li></ul></ul><ul><ul><ul><ul><ul><li>Reproduce asexually - spores </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Example: </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Mushrooms, molds, puffballs, lichens </li></ul></ul></ul></ul></ul>
  4. 4. Mushrooms and Toadstools Found in damp, shady places Very short lifespan Most are poisonous (if it is red it is poison) Some grown for commercial use
  5. 5. <ul><li>fungi which grow in symbiosis with algae, forming a structure in which the algal cells are imbedded in the fungal structure (hyphae) </li></ul><ul><li>the algae gets water and minerals from the fungus </li></ul><ul><li>the fungus gets food from the algae which is able to conduct photosynthesis </li></ul><ul><li>found on bare rocks in a crust like, shrub like, or leaf like form </li></ul><ul><li>can be used to make perfume or for dyes </li></ul>Lichens
  6. 6. Non-vascular Plant <ul><li>Nonvascular </li></ul><ul><ul><li>no vascular tissue </li></ul></ul><ul><ul><li>no leaves, stems, or roots </li></ul></ul><ul><ul><li>low growing, close to the ground </li></ul></ul><ul><ul><li>reach maturity quickly </li></ul></ul><ul><ul><li>can grow in varying climates </li></ul></ul><ul><ul><li>Produce food in every cell </li></ul></ul>
  7. 7. Mosses <ul><li>a flowerless plant </li></ul><ul><li>lies flat and grows in moist areas (carpet like appearance) </li></ul><ul><li>reproduces sexually </li></ul><ul><li>Economics - used by gardeners as a mulch because it helps keep moisture close to the plants roots. </li></ul>
  8. 8. Algae <ul><li>different shapes, sizes, and colors </li></ul><ul><li>simple plants that contain photosynthetic pigments (chlorophyll) </li></ul><ul><li>found in wet soil </li></ul>
  9. 9. Vascular Plants <ul><ul><li>has vascular tissue – tissue that moves food and nutrients around plant </li></ul></ul><ul><ul><li>leaves, stems, and roots </li></ul></ul><ul><ul><li>produces food for plant only in leaves </li></ul></ul>
  10. 10. <ul><li>May have a long life span – </li></ul><ul><li>one season or many </li></ul><ul><li>grows tall and wide </li></ul><ul><li>Has chlorophyll for photosynthesis </li></ul><ul><ul><ul><ul><ul><li>examples: ferns, trees, grasses and flowering </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>plants </li></ul></ul></ul></ul></ul>
  11. 11. Two Groups of Vascular Plants <ul><li>Gymnosperms - naked seed </li></ul><ul><li>Angiosperms -  vessel seed </li></ul>
  12. 12. Gymnosperm vs. Angiosperm <ul><li>Gymnosperm - </li></ul><ul><ul><li>expose their seeds </li></ul></ul><ul><ul><li>examples-pine, spruce, ferns and conifers trees </li></ul></ul>
  13. 13. <ul><li>Angiosperm </li></ul><ul><ul><li>produce and store their seeds in an ovary – often called fruit </li></ul></ul><ul><ul><li>examples - roses, elm trees, geraniums, apple trees, etc. </li></ul></ul>
  14. 14. Subclasses of Angiosperms <ul><li>A. Monocots – </li></ul><ul><ul><li>single seed leaf (cotyledon) </li></ul></ul><ul><ul><li>flowers/petals grow in groups of three </li></ul></ul><ul><ul><li>leaves have parallel veins </li></ul></ul>
  15. 15. <ul><li>Flowers often small, overlooked </li></ul><ul><li>Usually grow for only one year </li></ul><ul><li>Examples: corn, grasses, onions, lilies and many grains </li></ul>
  16. 16. Dicots <ul><ul><li>two seed leaves (cotyledons) </li></ul></ul><ul><ul><li>flowers/petals grow in groups of four or five </li></ul></ul><ul><ul><li>leaves have network veins that branch out </li></ul></ul>
  17. 17. <ul><ul><li>Examples: trees, sunflower, beans, pumpkins and clover . </li></ul></ul>Greatest number of plants are dicots Tend to live a long time – one season or many Produce food, clothing, housing
