    Study Notes

    Definition of Plants

    • Plants are multicellular eukaryotic organisms characterized by cell walls composed of cellulose and the presence of chloroplasts.
    • Specialized reproductive organs are present, producing sperm and eggs either on the same or different plants.

    Plant Life Cycles

    • Unlike animals, many plants reproduce through haploid spores instead of sperm and egg fusion.
    • Male and female plant forms can produce gender-specific spores, leading to distinct life stages separate from their genetic origins.
    • Plant development occurs through mitosis, allowing new individuals to grow independently from their parents.

    Evolutionary Context

    • Plants existed for hundreds of millions of years before evolving flowers, lacking structure such as leaves and stems in their earliest forms.
    • Traits defining plants include complex life cycles and unique reproductive strategies.

    Photosynthesis and Nutrition

    • The vast majority of plants (about 99%) photosynthesize, converting sunlight, carbon dioxide, and water into food.
    • A small fraction of plant species have lost this ability and have become heterotrophic, engaging in predation (e.g., Venus flytrap).
    • The Venus flytrap captures and digests insects using secreted enzymes to absorb nutrients.

    Plant Requirements for Survival

    • Essential conditions for plant growth include temperatures above freezing, sunlight, and access to carbon dioxide and water.
    • Plants require oxygen for cellular respiration and minerals for synthesizing proteins and organic molecules.

    Importance of Plants

    • Plants are foundational to life on Earth, supporting ecosystems and being vital for the survival of many organisms, including humans.
