Chapter 5 Summary

Key Takeaways

  • Land plants evolved from green algae and developed adaptations such as a waxy cuticle, stomata, roots, gametangia, and alternation of generations to survive and reproduce on land.
  • Bryophytes (nonvascular plants) were the first land plants and depend on moist environments due to their lack of vascular tissue and reliance on water for reproduction.
  • Seedless vascular plants like ferns evolved vascular tissues (xylem and phloem), lignin, and true roots, allowing greater height and habitat range, but still rely on water for fertilization.
  • Gymnosperms introduced pollen and seeds, enabling reproduction without water and better protection for embryos, which helped them thrive in drier environments.
  • Angiosperms evolved flowers and fruits, improving pollination and seed dispersal through animal interactions, making them the most diverse and widespread plant group.
  • Fungi differ from plants by absorbing nutrients from their environment, decomposing organic matter, forming mutualistic relationships, and contributing to medicine, food production, and ecosystem health.

  84. Steps:
    1. Gametophytes (n) produce gametes (n) through mitosis. Antheridium produces sperm. Archegonium produces egg.
    2. Sperm swim to nearby gametophytes to fertilize egg in the antheridium forming a zygote
    3. Zygote develops into embryo which then grows (through mitosis) into new sporophyte (2n).
    4. Sporophyte (2n) produces spores (n) through meiosis.
    5. Spores blow to a new location and grow into a new gametophyte (mitosis). The gametophyte is the conspicuous part of the plant.
  85. Steps:
    1. Gametophytes (n) produce gametes (n) through mitosis. Antheridium produces sperm. Archegonium produces egg.
    2. Sperm swim to nearby gametophytes to fertilize egg in the antheridium forming a zygote (2n).
    3. Zygote develops into embryo which then grows (through mitosis) into new sporophyte (2n). The sporophyte is the conspicuous part of the plant.
    4. Sporophyte (2n) produces spores (n) through meiosis.
    5. Spores blow to a new location and grow into a new gametophyte (mitosis).
  86. Steps:
    1. Gametophytes (n) produce gametes (n) through mitosis. Male gametophyte is a pollen grain found in male cones. Female gametophyte develops within an ovule in female cones.
    2. Pollen is carried by wind to fertilize egg forming a zygote (2n) inside the ovule of the female cone.
    3. Zygote develops into embryo. Ovule develops into seed.
    4. Seed is dispersed then germinates and grows (through mitosis) into new sporophyte (2n). The sporophyte is the conspicuous part of the plant (the tree).
    5. Sporophyte (2n) produces spores (n) through meiosis. Spores develop into gametophytes inside of cones.
  87. Steps:
    1. Gametophytes (n) produce gametes (n) through mitosis. Male gametophyte is a pollen grain in anther of flower. Female gametophyte (embryo sac) develops inside an ovule within ovary of flower.
    2. Pollen is transferred (by wind or pollinators) to stigma of a flower where it grows a pollen tube to fertilize egg inside ovule, forming a zygote (2n). This process includes double fertilization – second sperm fertilizes nearby cell to form endosperm which nourishes embryo.
    3. Zygote develops into embryo. Ovule becomes a seed and ovary develops into fruit.
    4. Seed is dispersed then germinates and grows (through mitosis) into a new sporophyte (2n). The sporophyte is the visible flowering plant.
    5. The sporophyte (2n) produces spores (n) through meiosis. Spores develop into gametophytes (pollen and embryo sacs) inside the flower.
