1. KINGDOM PLANTAE Vascular Plants Phylum Tracheophyta Seeds Subphylum Spermopsida Seeds ‘naked’ Seeds enclosed Class Gymnospermidia Sub Class Liliopsida MONOCOTS Sub Class Magnoliopsida DICOTS Class Angiospermidia

2. Subphylum Spermopsida (seed bearing plants) True roots (with vascular tissue) Reproduction without water (evolved flower) Protective covering around embryo (seed) – can survive winter Improved conducting tissue: thicker and stronger xylem. Became taller.

3. Class Angiospermidia Class Angiospermidia ‘enclosed seeds’ (flowering plants) 135 million years ago in the JURASSIC ERA. 1.Evolved (from a Gingko like tree) approximately 135 million years ago in the JURASSIC ERA. 235,000 to 300,000 species 2. 235,000 to 300,000 species (90% of Kingdom Plantae) Ubiquitous 3. Ubiquitous (found everywhere) 4. Not as dependent on wind as a means of reproduction. This greatly increased their chances of survival.

4. 5. Made improvements in reproduction to occupy areas vacated by the ferns. Adapted to more moderate climates.

9. PISTIL PISTIL (female) is made up of: STAMEN STAMEN (male) is made up of: Stigma – sticky and ‘catches’ pollen Style – carries pollen to the ovary Ovary – contains the eggs. Ovule – surrounds the eggs Anthers – produce pollen Filament – raises anthers in the air

11. ACCESSORY ORGANS ACCESSORY ORGANS: function in attracting the ‘VECTOR’ (pollinator/ seed distributor) with colour, odor and nectar. Petal: brightly coloured to attract vector Sepal: ‘leaves’; protects flower when it’s closed up Receptacle: releases odour Nectar: found at the base of the ovary

12. carpel 6. Seeds borne within a carpel Protection: a leaf like structure that encloses the seed. imple stamen 7. Pollen on a simple stamen: Small amount of pollen as compared to conifers. Less energy required. More energy is in the flower to ensure precise cross-pollination.

13. 8. Specialized pollen 8. Specialized pollen: The pollen grain is very specific to the female stigma (lock and key). Prevents inbreeding. 9. Double fertilization 9. Double fertilization: a) 1 pollen grain (sperm) fertilizes the egg to form a zygote  becomes an embryo The pollen grain also has enzymes to digest into the style and ovary. b) Another pollen grain fertilizes a polar nuclei  endosperm (food for the zygote) http://www.youtube.com/watch?v=Gq8NWh98wQs Double fertilization

15. 10. Leaves: reticulate or parallel venation 11. More developed vascular tissue (xylem and phloem)

17. Dicots Dicots (ie: rose, apple trees…) Two seed cotelydons Germinates and puts off 2 leaves Has a netted vein pattern Contains annuals, bi-annuals (2 years), perennials (every year) Herbaceous & woody forms

19. Order Magnoliidae Magnolia Tree Poppy Buttercup Water lily

20. Order Hamamelidae Elm Tree Oak Tree Birch Tree

21. Order Caryophyllidae Cactus Pinks Buckwheat

22. Order Dilleniidae Mallow, hibiscus… Pitcher plant Sundew, venus fly trap Some herbs

25. Catkins: Willow, Aspen, & Cottonwood trees Mustard plant Rhododendron

26. Order Rosidae Stone crop Rose hips Geraniums

27. Legumes Evening Primrose Mistletoe: a parasite on trees and shrubs Carrots, parsley

28. Grape Virginia Creeper Maple trees Poison Ivy

29. Order Asteridae Milkweed Nightshade (potatoe) Snapdragon

30. Daisy Gentian Morning Glory Olive

34. Monocots Monocots (ie: grass, grains, onions, lilies, tulips…) One seed cotelydon Germinates and puts off 1 leaf Has a parallel vein pattern Mostly annuals (grow 1 year and die) All are Herbaceous (non-woody)

36. Order Alismatidae Arrowhead

37. Order Arecidae Palm Trees Philodendron

38. Order Commelinidae Rush Spiderwort Sedge Grass

39. Bur-reed Cat tail

40. Pineapple Order Zingiberidae

41. Order Liliidae Lily Iris Orchid

42. FERTILIZATION A specific pollen lands on the stigma and grows a pollen tube to the ovary. One sperm (gametophyte) will fertilize the egg (gametophyte) to form a zygote. After fertilization, the zygote will grow to form an embryo. A 2 nd sperm fertilizes a diploid ENDOSPERM cell and this becomes triploid (3N). It grows rapidly, fills the ovule (which surrounds the embryo) and eventually becomes the SEED.

44. In most plants the seed develops inside the original ovary of the flower. ZYGOTE EMBRYO OVULE SEED OVARY FRUIT The seed is covered by the old ovary which grows and becomes the fruit. The fruit attracts animals which will eat it and then distribute the seeds in their feces.
