2. Flowers the reproductive structures of plants

3. Can you remember the Seven Processes of Life? MRSNERGMRSNERG

4. Movement Stems and leaves curve round to face the light. Light is needed by the leaves to make food. Plants - Seven Processes of Life

5. Reproduction Plants reproduce either sexually or asexually.

6. Plants - Seven Processes of Life Sensitivity Stems curve to face the light. Roots grow towards water.

7. Plants - Seven Processes of Life Nutrition Photosynthesis - the process of turning the sun’s energy, water and minerals into energy.

8. Plants - Seven Processes of Life Excretion Plant release oxygen. This is a waste product of photosynthesis.

9. Plants - Seven Processes of Life Respiration Plants take in Carbon dioxide (gas), They use this to make food.

10. Plants - Seven Processes of Life Growth Plant use the food made during photosynthesis to grow.

11. Classification Kings prefer coke over flavored grape soda

12. And the answer is: Kingdom Phylum Class Order Family Genus species

13. Classification: 6 Kingdoms  Animals  Plants  Fungi  Protists  Eubacteria  Archaebacteria

14. Plant Characteristics They make their own food –Chloroplasts contain chlorophyll –Chlorophyll absorbs energy from the sun –Plants use the energy to make food - glucose (sugar) –Process is called Photosynthesis

15. Chloroplasts:

16. Plant Characteristics Plants Have a Cuticle

17. What is a Cuticle? –A waxy layer that coats the surface of stems, leaves, and other plant parts exposed to the air. –Keeps plants from drying out.

18. Plant Characteristics Plant Cells have Cell Walls

19. What is a Cell Wall –a plant cell is surrounded by a rigid cell wall –outside of the cell membrane –helps support and protect the plant

20. Plant Characteristics Plants reproduce either asexually spores or sexually (pollen and egg)

22. How are Plants Classified? There are more than 260,000 species of plants. They can be divided into two groups: –Nonvascular Phylum –Vascular Phylum

23. How are Plants Classified? Nonvascular Plants: –have no special tissue to transport water and nutrients –depend on diffusion and osmosis to move material from one part of the plant to another –They have to be small: mosses, liverworts

24. Liverwort:

25. How are Plants Classified? Vascular Plants –Have tissues that deliver needed materials throughout a plant - called vascular tissues. –Can be almost any size. –Are divided into gymnosperms and angiosperms

26. How are Plants Classified? Gymnosperms -- “naked seed” non- flowering plants Angiosperms -- flowering plants

27. Vascular Plants Have a xylem and phloem –Xylem Hard wall cells that transport water and minerals Flows Upward –From roots Die every year Rings in a tree trunk

28. Vascular Plants Phloem –Soft-walled cells that transport organic nutrients –Travels downward Phloes downward! –This tissue is living and permanent –Primarily used for food transport

30. Flowers have 4 different parts Sepals Petals Stamens Pistil

31. Pedicel The flower stem

32. Sepals Usually green; leaflike structures that protect the flower, as it forms and emerges.

33. Sometimes sepals are colorful

34. Calyx The group of sepals on a flower

35. Petals Located just inside the sepals Leaf-like and often very colorful Attract pollinators

36. Corolla The collection of petals on a flower

37. The reproductive parts Found at the center of the flower

38. Stamens Male reproductive parts of a flower Arranged around the female parts

39. Anther Part of the stamen Produces and holds pollen

40. Filament Stalk that holds up the anther

41. Pistil The female part of the flower

42. Stigma Found at the end of the pistil Has a sticky surface to catch pollen

43. Style The neck of the pistil

44. Ovary Part of the pistil that contains the ovules

45. Ovule The part of the flower in which the eggs are produced and seeds develop

46. Complete flowers Have all 4 basic parts: Sepals, petals, stamens and pistil

47. Incomplete flowers Flowers that are missing one of the four basic parts

48. Perfect Flowers Flowers that have both male and female parts

49. Imperfect flowers Flowers that lack one of the sex structures

50. (female part) (makes eggs) (sticky)

51. (male part) (makes pollen)

52. stigma style ovary anther filament pollen

53. We know that plants produce flowers which have male and female organs. We know that seeds are formed when pollen from the male organ fertilises the female organ. We can label the parts of a plant and flower.
