Kingdom plantae

  2. 2. CLASSIFYING PLANTS• The terrestrial members of the Plant Kingdom are generally divided into 2 groups 1. Non Vascular or Bryophytes - lack specialized tissues for conduction of water 2. Vascular or Tracheopytes -have specialized tissues for transporting water and nutrients
  5. 5. CLASSIFYING PLANTS TWO SYSTEMS OF PLANT CLASSIFICATION 1.Natural System - Based on evolutionary relationships amongplants 2. Artificial System - based mainly on size, water requirement, ability to manufacture food, habitat and life span
  6. 6. Bases of Artificial System1. Size a. Microscopic - Those that are not visible to the unaided eye b. Macroscopic -those that can be seen with the unaided eye
  7. 7. Bases of Artificial System2. Water requirement a. Xerophytes -live in places with little amount of water b. Mesophytes -require a moderate amount of water c. Hydrophytes -live in habitats with abundant water
  11. 11. Bases of Artificial System3. Ability to manufacture food a. Autotrophic -plants that manufacture their own food b. Heterotrophic -plants that depend on other organisms or dead organic matter for food
  12. 12. Heterotrophic Plant
  13. 13. Bases of Artificial System4. Habitat a. Aquatic - plants live in water b. Terrestrial - plants live on land c. Aerial - plants live above the ground
  14. 14. Bases of Artificial System5. Life Span a. Annual - live for one growing season ex. Onions, garlic, patola b. Biennials - complete their life cycle in 2 years ex. Okra, parsley, sunflower c. Perennials - live for many years
  15. 15. Bases of Artificial System6. Habit – refers to body appearance a. Trees- woody perennial plants with a single stem or trunk b. Shrubs – plants with several main stems arising at or near the ground c. Herbs-come with soft stem d. Vines- climbing plants
  16. 16. TREES
  17. 17. VINES
  18. 18. HERBS
  19. 19. SHRUBS
  20. 20. NONVASCULAR PLANTS• They live in moist and damp places since they do not have xylem and phloem to move water from one part to another• They are usually small in size due to this missing part • Bryophytes do not have true roots, stem and leaves
  21. 21. NONVASCULAR PLANTS• They are called thalloid plants• These plants grow from spores• Composed of mosses, liverworts and hornworts • they are regarded as the “amphibians” of the plant world since they need a lot of water even if they are terrestrial in habitat
  22. 22. LIVERWORTS
  23. 23. NONVASCULAR PLANTS1. LIVERWORTS - liver because of its liver shape appearance and wort, which means plant or herb -2 types of gametophyte 1. Antheridium- male reproductive that produces the sperm cell 2. Archaegonium- female reproductive that produces the egg cell
  24. 24. HORNWORTS
  25. 25. NONVASCULAR PLANTS2. HORNWORTS -they seldom exceed 2 cm in height - usually found in moist soil and shaded areas or may be attached to trees
  26. 26. MOSSES
  27. 27. NONVASCULAR PLANTS3. MOSSES - are of 2 types; the gametophyte and the sporophyte - they differ from any other plants because of the absence of mesophyll tissues, stomata and veins
  28. 28. WHISK FERN
  29. 29. VASCULAR PLANTS1. WHISK FERNS - small plants with fork like branches that look like a broom - they are considered the simplest of all living vascular plants
  30. 30. CLUB MOSSES
  31. 31. VASCULAR PLANTS2. CLUB MOSSES - they just grow wildly and luxuriantly along the roadside specially during rainy season - the spores are found on their tips
  32. 32. HORSETAIL
  33. 33. VASCULAR PLANTS3. HORSETAILS - its stem are rough with silica crystals, Thus, it is ideal for scrubbing pots and dirty kettles
  34. 34. FERNS
  35. 35. VASCULAR PLANTS4. FERNS - the largest group of seedless vascular plants - they may reach 3 to 5 meters in height - they have vascular tissues and strong roots
  36. 36. GYMNOSPERMS• Came from the Greek word „gymnos‟ meaning naked and „sperma‟ seed or naked seeds• They are cone bearing plants• They grow very well in temperate region
  37. 37. GINKGO
  38. 38. GYMNOSPERMS1. Ginkgos - Ginkgo biloba as its popular name - Large tree with numerous spreading branches - Leaves are fan shape that gives off a pungent odor
  39. 39. GNETUMS
  40. 40. GYMNOSPERMS2. GNETUMS - believe to be the ancestor of the flowering plants - have cones that resembles a flower - smaller than ginkgo. Not common in the Philippines
  41. 41. CYCADS
  42. 42. GYMNOSPERMS3. CYCADS -second largest group of gymnosperms -leaves are compound and composed of several leaf-like parts -they grow well in tropical countries
  43. 43. CONIFERS
  44. 44. GYMNOSPERMS4. CONIFERS - biggest group of gymnosperms found in most part of the world - large, tall trees with highly branched stems - leaves are usually long, scaly, and needle-like
  45. 45. ANGIOSPERMS• Vascular plants that bear flowers and produced fruits with seeds that are usually found inside the fruit• There are two kinds of flowering plants based on the number of cotyledons. A.Monocotyledon B.Dicotyledon
