1. Scientific Identification & Classification

2. Plant Parts Leaves Stems Roots Flowers

3. Leaves-External Petiole-leaf stalk or part that connects the leaf to the stem Blade-the large, flat part of the leaf Midrib-the large center vein Veins-the structural framework of the leaf Margin-the edge of the leaf

4. Leaves-External

5. Leaf Retention Evergreen-Leaves stay on the plant all year long Deciduous-Leaves will fall off during the dormant periods Herbaceous-leaves and stems die back at the end of the season

6. Leaf Type

8. Leaf Shapes CordateElliptical Ovate SpatulateDeltoid LanceolateLiner

9. Leaf Margin

10. Leaf Arrangement AlternateOppositeWhorled

11. Vein Pattern

12. Stems Movement of Materials Support of the leaves and reproductive structures Food storages Reproduction with stem cuttings or grafting

13. Stems-External Lenticels Bud scale scars Leaf Scars Terminal bud Axillary or lateral bud

14. Thorns & Prickles Thorn Prickle

15. Modified Stems Stolon Tuber Cladophyll

16. Root Functions Anchor the plant and hold it upright Absorb water and minerals from the soil and conduct them to the stem Store large quantities of plant food Propagate or reproduce some plants

17. Roots-External Root cap-indicates growth of new cells Root hairs-absorb moisture (water) and minerals Root images from a rice plant

18. Root Types Fibrous Roots Tap Root

19. Layers of Roots Fibrous-many branched shallow roots –are easier to transplant Tap-long root with few branched ones –more difficult to transplant

20. Flowers Sepals-Green parts that cover and protect flower bud before it opens Petals-are really leaves that are modified to attract insects for flower pollination, the pretty part that we call flowers Stamen-male part of the flower Pistil-female part of the flower

21. Flowers

22. Parts of the Stamen Filament-short stalk that holds up the anther Anther-a sac-like structure that contains pollen, the male sex cells

23. Parts of the Pistil Stigma-sticky part on top of style where insects leave pollen Style-holds up the stigma and connects it to the ovary Ovary-if fertilized becomes a fruit or seed coat Ovules-the eggs or female sex cells that become seeds if fertilized

24. Complete-vs-Incomplete Complete flowers have both male and female parts Incomplete flowers have only male or female parts

25. Monoeciuos All male or all female flowers on plant Examples: Hollies or Ginkgo MaleFemale

26. Dioecious Male and female, imperfect flowers on same plant Examples: Squash & Pumpkin

27. Flower Types CorymbsPanicle Spike

28. Flower Types Umbel Head

29. Plant Parts-Fruit Cones Nut (acorn) Clusters or drupes (raspberry) Capsules (willow) Samara (maple)

30. Fruits and Nuts Cones Acorns Cluster Drupe

31. Fruits and Nuts Samara Capsule Pome

32. Life Cycle Annual-a plant that lives for only 1 year or less Biennial-a plant that lives for 2 years, usually flowering in the second year Perennial-a plant that lives for more than 2 years

33. Growth Habits Trees: greater than 12 feet tall Shrubs: less than 12 feet tall Vines: a plant that climbs & spreads

34. Growth Habits House Plant: plant grown indoors Bedding Plant: a plant used in flowering beds

35. Forms of Plants: Growth Pattern Spreading Weeping Columnar

36. Growth Forms Round Oval Pyramidal
