    Study Notes

    Plant Classification

    • Monocots: Angiosperms characterized by a single seed leaf.
    • Dicots: Angiosperms that develop two seed leaves.

    Plant Structures and Functions

    • Stomata: Microscopic openings on leaf undersides facilitating gas exchange; crucial for oxygen and carbon dioxide movement.
    • Xylem: Vascular tissue responsible for upward water transport from roots to all plant parts.
    • Phloem: Living vascular tissue that transports sugars and organic substances throughout the plant.
    • Vascular Tissue: Composed of tubular cells that move water and nutrients, essential for plant health.

    Plant Properties and Processes

    • Water Potential: Determines water movement direction based on solute concentration and pressure; key in plant hydration and nutrient uptake.

    Types of Seed Plants

    • Angiosperms: Flowering plants with seeds enclosed in an ovary; essential for fruit and seed development.
    • Gymnosperms: Seed-producing plants with exposed seeds, not enclosed in fruits.

    Growth Regulators

    • Gibberellins: Hormones that promote stem and leaf growth, seed germination, bud dormancy breaking, and fruit development.

    Plant Organs

    • Roots: Anchor plants and absorb water and minerals; foundational for plant stability and growth.
    • Leaves: Main sites for photosynthesis and transpiration; critical for energy production.
    • Stems: Structural support connecting roots and leaves, facilitating water and nutrient transportation.
    • Rhizomes: Horizontal underground stems that serve as storage and propagation organs.

    Reproductive Structures

    • Frond: Refers to a fern leaf or leaves of palms and bananas.
    • Cone: Gymnosperm reproductive structure; crucial for seed production.
    • Flower: The reproductive structure of angiosperms; central to sexual reproduction in these plants.
    • Pollen Grain: Male gametophyte in seed plants; essential for fertilization.
    • Pollination: Process of transferring pollen from male to female structures; vital for seed production.
    • Seed: A protective package consisting of an embryo, nutrient store, and coat; essential for reproduction in terrestrial plants.
