Transcript of "Introduction to plants 1233859493415311-3"

  1. 1. PlantsSection One
  2. 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. 3. Adaptations of Plants onLand  #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. 4. Adaptations of Plants onLand  #2 Preventing Water Loss – to survive on land, plants evolved a waxy outer covering called a cuticle and stomata for gas exchange.

  6. 6. Cuticle and StomaSketches Stoma Cuticle Cross Section
  7. 7. Adaptations of Plants onLand  #3 Reproducing on Land – To survive on land, plants use pollen to reproduce without water. Pollen on an ant
  8. 8. Adaptations of PlantTissues  #1 Advantages of Conducting Tissues – Vascular plants have a system of well-developed tissues that transport water in a plant.
  9. 9. Adaptations of PlantTissues  #2 Advantages of seeds – Seeds protect and nourish a plants embryo
  10. 10. Adaptations of PlantTissues  #3 Advantages of Flowers – Flowers make reproduction more efficient by promoting pollination.
  11. 11. Kinds of Plants simple complex  Nonvascular Plants  Small  Lack vascular tissue  Examples = moss, liverworts and hornworts It’s easy to see how “Hornworts got their names!This moss is used to determine levels of Liverworts in central pollutants Texas
  12. 12. Kinds of Plants simple complex  Seedless Vascular Plants  Produce spores with thickened walls to prevent them from drying out.  Include ferns, club mosses, horse tailsSpores on the underside of fern leaves. Horse tails Club mosses in Canada
  13. 13. Kinds of Plants simple complex  Gymnosperms  Seed plants that produce cones  Include conifers, cycads and ginkgoesSpores on the underside of fern leaves. The unique fan-like An old pine tree in leaves of the ginkgo tree California
  14. 14. Kinds of Plants simple complex  Angiosperms  Seed plants that produce fruit and flowers.  Divided into 2 main groups Yep, grass flowers too A large Sugar Maple TreeSunflowers in a field

  28. 28. Reproduction in Seed Plants Section 2 Reproduction in Plants section 2
  29. 29. Sexual Reproduction in SeedPlants  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. 30. Important Vocabulary1  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. 31. Important Vocabulary2  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. 32. Important Vocabulary3  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. 33. Important Vocabulary4  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. 34. ReproductiveStructures Tiny gametophytes of seed plants develop from spores that remain within saprophyte tissues.
