    Study Notes

    Diversity of Plants

    • Plants play a vital role in human societies, offering nutrition, medicine, and industrial products
    • Plants are essential for the Earth's physical terrain and climate
    • Plants exhibit a single common ancestor
    • Transition to land required adaptations for water retention, dispersal, structure, and sunlight filtration
    • Approximately 300,000 plant species are documented
    • Most plants are photosynthetic, but some are parasitic
    • Plant cells have cellulose walls
    • Plant reproduction is mostly sexual, but asexual reproduction is also common
    • Plant growth is indeterminate, meaning they continue to grow until death

    Plant Adaptations to Life on Land

    • Land plants face challenges like desiccation and needing support in air, along with methods of gamete dispersion

    • Successful land plants developed adaptations like drought tolerance to avoid desiccation

    • Structural support in air, gamete and zygote protection are needed.

    • Water is essential; maintaining hydration is a crucial challenge in a terrestrial environment

    • Plants exhibit alternation of generations

    Sporangia in Seedless Plants

    • Sporophyte in seedless plants is diploid
    • Spores are produced by meiosis within sporangia
    • Sporangia are reproductive sacs containing spores
    • Spores are released into the environment and germinate
    • Two different spore types in heterosporous plants, microspores and megaspores
    • Multicellular gametophyte forms from haploid spore

    Gametangia in Seedless Plants

    • Gametangia are structures in gametophytes, where gametes are produced by mitosis
    • Male gametangium (antheridium) produces sperm
    • Female gametangium (archegonium) produces eggs
    • Sperm (in species with flagella) requires moisture for movement
    • Embryo develops within archegonium and is nourished by the gametophyte

    Additional Land Plant Adaptations

    • Plants adapted new organs and structures to thrive on land
    • Vascular tissue for water and nutrient transport (xylem and phloem) evolved
    • Roots evolved for support and water/nutrient absorption
    • A protective cuticle on aerial parts prevents water loss
    • Secondary compounds protect from predation
    • Some plants evolved strategies to attract animal allies for dispersal

    Paleobotany

    • Paleobotany studies extinct plants to understand evolution and ecosystems
    • Fossils are formed when organisms are trapped in sediments that preserve their shape
    • Chemical analysis of fossils helps in tracing evolution
    • Molecular fossils like oleanane can provide insights into early lifeforms
