Transcript

  • 1. Plants Section One
  • 2. Objectives
    • Summarize how plants are adapted to living on land.
    • Distinguish nonvascular plants from vascular.
    • Relate the success of plants on land to seeds and flowers.
    • Describe the basic structure of a vascular plant.
  • 3. Adaptations of Plants on Land
    • #1 Absorbing Nutrients – To survive on land, plants evolved the ability to absorb mineral nutrients from the soil.
    Nodules full of nitrogen-fixing bacteria on the roots of a soy bean plant
  • 4.
    • #2 Preventing Water Loss – to survive on land, plants evolved a waxy outer covering called a cuticle and stomata for gas exchange.
    Adaptations of Plants on Land
  • 5. Cuticle and Stoma Sketches Cuticle Cross Section Stoma
  • 6. Cuticle and Stoma Sketches Cuticle Cross Section Stoma
  • 7. Adaptations of Plants on Land
    • #3 Reproducing on Land – To survive on land, plants use pollen to reproduce without water.
    Pollen on an ant
  • 8. Adaptations of Plant Tissues
    • #1 Advantages of Conducting Tissues – Vascular plants have a system of well-developed tissues that transport water in a plant.
  • 9. Adaptations of Plant Tissues
    • #2 Advantages of seeds – Seeds protect and nourish a plants embryo
  • 10. Adaptations of Plant Tissues
    • #3 Advantages of Flowers – Flowers make reproduction more efficient by promoting pollination.
  • 11. Kinds of Plants
    • Nonvascular Plants
      • Small
      • Lack vascular tissue
      • Examples = moss, liverworts and hornworts
    simple complex This moss is used to determine levels of pollutants Liverworts in central Texas It’s easy to see how “Hornworts got their names!
  • 12. Kinds of Plants
    • Seedless Vascular Plants
      • Produce spores with thickened walls to prevent them from drying out.
      • Include ferns, club mosses, horse tails
    simple complex Spores on the underside of fern leaves. Horse tails Club mosses in Canada
  • 13. Kinds of Plants
    • Gymnosperms
      • Seed plants that produce cones
      • Include conifers, cycads and ginkgoes
    simple complex Spores on the underside of fern leaves. The unique fan-like leaves of the ginkgo tree An old pine tree in California
  • 14. Kinds of Plants
    • Angiosperms
      • Seed plants that produce fruit and flowers.
      • Divided into 2 main groups
    simple complex Sunflowers in a field Yep, grass flowers too A large Sugar Maple Tree
  • 15. Monocots Verses Dicots Floral Parts in 4’s or 5’s Floral Parts in 3’s
  • 16. Monocots Verses Dicots Net-like leaf veins Parallel leaf veins
  • 17. Monocots Verses Dicots Taproot System Fibrous root system
  • 18. Monocots Verses Dicots Vascular tissue in rings Vascular Tissue Scattered
  • 19. Monocots Verses Dicots Includes: Roses, oaks, sunflowers and most non-conifer trees. Includes: grass, lilies, orchids, and palm trees. Vascular tissue in rings Vascular Tissue Scattered Taproot System Fibrous root system Net-like leaf veins Parallel leaf veins Floral Parts in 4’s or 5’s Floral Parts in 3’s

    • Fruits and vegetables
    • Crops
    • Wood
    • medicine
    • Fibers
  • 28. Reproduction in Plants section 2 Reproduction in Seed Plants Section 2
  • 29. Sexual Reproduction in Seed Plants
    • Objectives
      • Distinguish the male and female gametophytes of seed plants.
      • Describe the function of a seed.
      • Relate the parts of a flower to their function
      • Summarize the life cycle of an angiosperm
  • 30. Important Vocabulary 1
    • anther
      • The pollen bearing portion of a stamen in flowering plants.
    • carpels
      • A leaf like floral structure enclosing the ovule or ovules of angiosperms.
    • corolla
      • Petals, collectively; usually the colored flower parts.
    • egg
      • A female gamete.
    • embryo sac
      • The female gametophyte of a flowering plant, inside the ovule.
  • 31. Important Vocabulary 2
    • endosperm
      • In plants a triploid tissue containing stored food, develops from the union of a sperm nucleus and two nuclei of the central cell of the female gametophyte. Found only in angiosperms.
    • filament
      • A chain of cells, but in flowers it is the stalk of a stamen.
    • fruit
      • In angiosperms a matured, ripened ovary or group of ovaries and associated structure. Contains the seeds.
    • gametophyte
      • The haploid (n) gamete producing gerneration (plants have alternating haploid and diploid generations).
  • 32. Important Vocabulary 3
    • ovary
      • In flowering plants the enlarged basal portion of a carpel or fused carpel containing the ovule or ovules. Ovary matures to become the fruit.
    • ovules
      • In seed plants a structure composed of a protective outer coat, a tissue specialized for food storage, and a female gametophyte with an egg cell. Becomes a seed after it is fertilized.
    • pollen
      • In seed plants, spore consisting of an immature male gametophyte and a protective outer covering.
    • seed
      • A complex structure formed by the maturation of the ovule of seed plants following fertilization; upon germination a seed develops into a plant. Seed is made up of a seed coat, embryo and a food reserve.
  • 33. Important Vocabulary 4
    • stamens
      • The male structure of a flower which produces pollen.
    • stigma
      • In plants, the region of a carpel serving as a receptive surface for pollen.
    • style
      • In angiosperms, the stalk of a carpel which the pollen tube grows through.
    • zygote
      • The diploid (2n) cell resulting from the union of male and female gametes (fertilization).
  • 34. Reproductive Structures
    • Tiny gametophytes of seed plants develop from spores that remain within saprophyte tissues.
