25. Water Loss in Plants
The graph shows how much water a certain plant loses during the hours shown.

26. Water Loss in Plants Reading Graphs:
What variable is plotted along each axis?
Horizontal axis–time of day; vertical axis–water loss.

27. Water Loss in Plants Interpreting Data:
According to the graph, during what part of the day did the plant lose the most water? The least water?
Most–midday; least–in the evening.

28. Water Loss in Plants Drawing Conclusions:
What could account for the pattern of water loss shown?
The plant seemed to lose the most water during the sunniest or warmest parts of the day.

29. Water Loss in Plants Predicting:
How would you expect the graph to look from 10 p.m. to 8 a.m.? Explain your reasoning.
The line graph would descend during the night and then rise again in the morning hours, because the water loss is less during the night when there is no sun.

30. Section 10.2: Plants Without Seeds
What characteristics do the three groups of nonvascular plants share?
What characteristics do the three groups of seedless vascular plants share?

31. Mosses
A moss gametophyte is low-growing and has structures that look like roots, stems, and leaves.
The stalklike sporophyte generation remains attached to the gametophyte.

32. MOSS HORNWORTS AND LIVERWORTS
LOW GROWING IN MOIST AREAS NO XYLEM (WATER) OR PHLOEM (FOOD) TISSUE ABSORB WATER FROM THEIR ENVIRONMENT

33. Characteristics of Seedless Vascular Plants
Ferns, club mosses, and horsetails share two characteristics. They have true vascular tissue and they do not produce seeds. Instead of seeds, these plants reproduce by releasing spores.

34. Ferns
Most ferns have underground stems (rhizoids) in addition to roots. The leaves, or fronds, grow above ground.

35. Ferns reproduce with spores

36. Ferns Complex Life Cycles
Ferns have complex life cycles that include two different stages: the sporophyte stage and the gametophyte stage.

SCOURING RUSHES IN COLONIAL TIMES

38. CLUB MOSSES…….PRINCESS PINES
SEEDLESS VASCULAR PLANTS. ALSO CALLED GROUND PINE OR PRINCESS PINE LOOKS LIKE A SMALL BRANCH OF A PINE TREE.

39. Section 10.3: The Characteristics of Seed Plants
What characteristics do seed plants share?
How do seeds become new plants?

40. What Is a Seed Plant?
The stems of vascular plants contain bundles of phloem and xylem. In addition, thick cell walls and vascular tissue help support the plant.

41. PARTS OF A SEED
AN EMBRYO (THE BABY PLANT). SEED COAT (SKIN OF SEED). COTYLEDONS (STORED FOOD FOR BABY PLANT).

42. HITCHING A RIDE WATER (COCONUTS) WIND ANIMALS
SEED DISPERSAL

43. How Seeds Become New Plants
A seed has three main parts–an embryo, stored food, and a seed coat. If a seed lands in an area where conditions are favorable, the plant sprouts out of the seed and begins to grow.

44. GERMINATION
BEGINS WHEN THE SEED ABSORBS WATER FROM THE ENVIRONMENT AND STARTS TO SPROUT AND GROW

45. Section 10.4: Roots, Stems, and Leaves
What are the main function of roots,
stems, and
leaves?

46. Root Structure
A root’s structure is adapted for absorbing water and minerals from the soil.

47. Stems
The stem produces branches, leaves, and flowers. It carries substances between the plant’s roots and leaves, and provides support for the plant.

48. Stems
Trees have woody stems. A typical woody stem is made up of many layers. The layers of xylem form annual rings that can reveal the age of the tree and the growing conditions it has experienced.

49. Leaves UPPER AND LOWER LAYERS =EPIDERMIS
IN MIDDLE OF LEAF VEINS OF XYLEM AND PHLOEM
PORES ON UNDERSIDE OF LEAF= STOMATA .
Leaves

50. Section 10.5: Reproduction in Seed Plants
What are the characteristics of gymnosperms and how do they reproduce?
What are the characteristics of angiosperms?
How do angiosperms reproduce?
What are the two types of angiosperms?

51. GYMNOSPERMS AND ANGIOSPERMS

52. GYMNOSPERMS
HAVE NAKED SEEDS NOT ENCLOSED IN A PROTECTIVE FRUIT NEEDLE-LIKE LEAVES DEEP ROOTS OLDEST OF THE SEED PLANTS (360 MILLION YEARS) CYCADS-PALM TREES WITH CONES. GINKGOS (Ginkgo biloba). GNETOPHYTES GROW IN VERY DRY DESERTS OF AFRICA CONIFERS- OUR PINE TREES: CEDARS, HEMLOCK, REDWOODS, JUNIPERS, and PINE.

53. Reproduction in Gymnosperms
First, pollen falls from a male cone onto a female cone. In time, a sperm cell and an egg cell join together in an ovule on the female cone. After fertilization occurs, the seed develops on the scale of the female cone.

54. The Structure of Flowers
Flowers come in all sorts of shapes, sizes, and colors. But, despite their differences, all flowers have the same function–reproduction.

55. Reproduction in Angiosperms
First, pollen falls on a flower’s stigma. In time, the sperm cell and egg cell join together in the flower’s ovule. The zygote develops into the embryo part of the seed.

56. Types of Angiosperms
Angiosperms are divided into two major groups: monocots and dicots.

57. Multiples
Is a flower with 6 petals a monocot? To answer this question you need to determine if 6 is a multiple of 3. A number is a multiple of 3 if there is a nonzero whole number that, when multiplied by 3, gives you that number. In this case, 6 is a multiple of 3 because you can multiply 2 (a nonzero whole number) by 3 to get 6.
2 x 3 = 6
Therefore, a flower with 6 petals is a monocot. Other multiples of 3 include 9 and 12.

58. Multiples Practice Problem Which of these numbers are multiples of 4?
6, 10, 12, 16
12 and 16
