  1. 1. PLANT KINGDOM
  2. 2. Main Characteristics <ul><li>Eukaryotic cells </li></ul><ul><li>Have cell walls made of cellulose </li></ul><ul><li>Autotrophic – Photosynthetic </li></ul><ul><li>Adapted to nearly every environment on earth. </li></ul><ul><li>Sexual and asexual reproduction </li></ul>
  3. 3. Classification <ul><li>Vascular Plants </li></ul><ul><li>Have tissues that make up a system that carries water, nutrients and other substances. </li></ul><ul><li>Non-vascular Plants </li></ul><ul><li>Have no vascular tissue and substances are transported through the cell walls. </li></ul>
  4. 4. Seedless plants <ul><li>Seedless nonvascular plants </li></ul><ul><li>Liverworts and mosses (Bryophytes). </li></ul><ul><li>small, 2 – 5 cm in height. </li></ul><ul><li>Have stalks and leafy green growths. </li></ul><ul><li>Have rhizoids. </li></ul><ul><li>Pioneer species. </li></ul><ul><li>Reproduce by spores. </li></ul>
  5. 5. Seedless plants <ul><li>Seedless vascular plants </li></ul><ul><li>Ground Pines and Spike Mosses </li></ul><ul><li>Reproduce by spores. </li></ul><ul><li>Spores produced in cones. </li></ul><ul><li>Needlelike leaves. </li></ul>Spike Mosses Ground Pines
  6. 6. Seedless plants <ul><li>Seedless vascular plants </li></ul><ul><li>Horsetails </li></ul><ul><li>Reproduce by spores </li></ul><ul><li>Stem structures. </li></ul><ul><li>Vascular tissue forms rings. </li></ul><ul><li>Spores produced in a conelike structure at the tips of the stem. </li></ul>
  7. 7. Seedless plants <ul><li>Seedless vascular plants </li></ul><ul><li>Ferns </li></ul><ul><li>Reproduce by spores. </li></ul><ul><li>Largest group of seedless vascular plants. </li></ul><ul><li>Spores are formed in round structures on the back of the leaves or in a separated stem. </li></ul>
  8. 8. Seed plants <ul><li>Vascular Tissue : </li></ul><ul><li>Xylem: Transports water and dissolved substances from the roots up to the leaves. </li></ul><ul><li>Have roots, stems, leaves and vascular tissue. </li></ul><ul><li>Seeds contain an embryo and stores food. </li></ul>Phloem: Transports food from where is made to other plants of the plant.
  9. 9. Seed plants <ul><li>Stem </li></ul><ul><li>Supports the structures, allows movement of materials. </li></ul><ul><li>Can be herbaceous or woody. </li></ul><ul><li>Roots </li></ul><ul><li>Moves substances up to the stems, anchor plants, store food (carrots). </li></ul><ul><li>Leaves </li></ul><ul><li>Trap light and produce food. </li></ul><ul><li>Have stomata to exchange gases and water. </li></ul>
  10. 10. Seed plants <ul><li>Gymnosperms: </li></ul><ul><li>“ naked seed” the seed is not protected by a fruit. </li></ul><ul><li>Divided in four groups. The most common is the conifers . </li></ul><ul><li>Examples: Pines, spruces. </li></ul>
  11. 11. Seed plants <ul><li>Angiosperms: </li></ul><ul><li>Flower and produce fruits containing the seed. </li></ul><ul><li>- Monocots and dicots </li></ul><ul><li>Examples: Palms, Garden flowers, Cacti, Grains, Vegetables. </li></ul>
  12. 12. <ul><li>Monocots </li></ul><ul><li>Have one cotyledon (seed leaf inside a seed) </li></ul><ul><li>Roots as fibers. </li></ul><ul><li>Leaves with parallel veins. </li></ul><ul><li>Flower parts in multiples of 3. </li></ul><ul><li>Vascular tissue spread. </li></ul><ul><li>Examples: Lilies, corn, rice, oats, palms, wheat . </li></ul><ul><li>Dicots </li></ul><ul><li>Have two cotyledons (seed leaf inside a seed) </li></ul><ul><li>Thicker roots. </li></ul><ul><li>Leaves with branched veins. </li></ul><ul><li>Flower parts in multiples of 4 or 5. </li></ul><ul><li>Vascular tissue in a ring. </li></ul><ul><li>Examples: Daisies, oak, tomato, carrot, cactus, roses. </li></ul>
