Seed Bearing Plants
 Gymnosperms
are vascular
plants that
produce seeds
on scales of
woody strobili
called cones.
 In other words, they have
naked seeds - seeds not
enclosed in a fruit.
 The four divisions of Gymnosperms
are:
–Cycadophyta
–Ginkgophyta
–Gnetophyta
–Pinophyta
 Cycads have a terminal rosette of leaves
and bear seeds in cones.
 All cycads have separate male and female
plants.
 Division
Ginkgophyta has
only on living
species – Ginkgo
biloba.
 The leaves are
lobed.

  9. 9.  Kingdom Plantae  Over 325, 000 species of plants known  Have different characteristics with different sizes ranging from microscopic to macroscopic  Diversity of plant forms leads to classification  Various classification scheme - based on water requirements - based on habitat or environment location -based on life duration -based on natural system classification -based on their habit of body appearance FORM OF PLANTS
  10. 10. Autotrophic or independent plants - Can manufacture their own food - Include ALL green plants which make their organic food by PHOTOSYNTHESIS - Also few non-green plants just like bacteria which manufacture their organic food
  11. 11. A. Based on Water Requirements 1. Mesophytes – those which require moderate supply of water. 2. Xerophytes – those which live in deserts or dry places and can withstand scanty supply of water. 3. Hydrophytes – those which thrive in watery or moist places and require abundant supply of water. 4. Halophytes- those which live in watery places, but in which the water is
  12. 12. Mesophytes Rosa multiflora Leucanthemum vulgareSolidago canadensis
  13. 13. Xerophytes Cereus peruvianus Euphorbia virosa
  14. 14. Hydrophytes- aquatic plants Water lilies Nymphaea alba Nelumbo nucifera Water hyacinth
  15. 15. Halophytes Seagrasses are found on the seaward edges of lagoons Mangroves Salicornia bigelovii
  16. 16. B. Based on their habitat or environment location 1. Aquatic plants- live in water 2. Terrestrial plants- live on land 3. Aerial plants- are above- ground and attached to other plants
  17. 17. C. Based on their life duration 1. Annual plants – live for one year or only one growing season 2. Biennial plants – live for two years. The first year is mainly limited to vegetative growth, and the second year is its reproductive year 3. Perennial plants – live from year to year or more than two years
  18. 18. Examples:  annual plants - corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia, marigold and etc.  biennial plants - onion, parsley, carrot, and etc.  perennial plants – fruits like avocado,pineapple, strawberry, banana,apple,tomato and etc.. -herbs like garlic, basil, oregano, ginger, black pepper and etc... -vegetables like okra, potato, gabi, camote, eggplant and etc - shrubs and trees
  19. 19. D. Based on their habit of body appearance 1. Trees – woody plants with single main stem which is commonly about 20 ft in length 2. Shrubs– woody plants in a relatively short 3. Herbs – plants with soft or succulent stems 4. Vines- climbing or twining plants, with stems which may be tender or tough
  20. 20. Nonvascular Plants- lack vascular plants´ specialized means of transporting water and organic nutrients, do not have true roots, stems and leaves. a. Division Hepatophyta (liverworts) b. Division Bryophyta (mosses) c. Division Anthocerophyta (hornworts) E. Based on natural systems of classification
  21. 21. Seedless Vascular Plants: a. Division Psilotophyta (whisk ferns) b. Division Lycopodophyta (club mosses) c. Division Equisetophyta (horsetails) d. Division Pteridophyta (ferns) Seed Vascular Plants: Gymnosperms a. Division Pinophyta (conifers) b. Division Cycadophyta (cycads) c. Division Gingkophyta (maidenhair tree) d. Division Gnetphyta (gnetophytes) Angiosperms a. Division Magnoliophyta (flowering plants) Class Magnoliopsida (dicots) Class Liliopsida (monocots)
  22. 22.  Divisions Bryophyta, Hepatophyta, Anthocerophyta –liverworts, mosses, hornworts. All are non- vascular and non-seed.
  23. 23. Seedless vascular plants
  24. 24. Divisions Psilotophyta, Lycopodophyta, Equisetophyta, Pteridophyta whisk ferns, horsetails, and ferns vascular and non-seed.
  25. 25. Seed Bearing Plants
  26. 26.  Gymnosperms are vascular plants that produce seeds on scales of woody strobili called cones.
  27. 27.  In other words, they have naked seeds - seeds not enclosed in a fruit.
  28. 28.  The four divisions of Gymnosperms are: –Cycadophyta –Ginkgophyta –Gnetophyta –Pinophyta
  29. 29.  Cycads have a terminal rosette of leaves and bear seeds in cones.  All cycads have separate male and female plants.

  31. 31.  Division Gnetophyta has 3 genera: – Gnetum – Ephedra – Welwitschia
  32. 32.  Pinophyta is the largest and most diverse division of the gymnosperms.  Most are evergreen – keeping their leaves year-round.  A very few are deciduous – dropping all of their leaves at the same time
  33. 33. Angiosperms include one division - Magnoliophyta
  34. 34.  Though there is only one division of angiosperms, Magnoliophyta ….  It is the largest and most diverse group of seed plants on Earth.  Magnoliophytes produce flowers, then seeds enclosed in a fruit.  Magnoliophytes can be annuals, biennials, or perennials.
