    Study Notes

    Plant Classification

    • Plants can be classified into flowering and non-flowering plants.
    • Flowering plants produce flowers, which later turn into fruits with seeds inside them.
    • Non-flowering plants reproduce in other ways.
      • Conifers produce seeds in cones.
      • Ferns and mosses produce spores.

    Plant Parts

    • The root system is responsible for absorbing water and minerals from the soil.
    • The root hair is a fine, thread-like structure that enables the roots to absorb water and nutrients.
    • There are two types of root systems: tap root systems and fibrous root systems.
    • The stem provides support for the plant and transports water and nutrients throughout the plant.
    • Hardened stems of trees are called trunks.
    • The leaves contain chlorophyll, a green substance that allows them to make food through photosynthesis.
    • Flowers are the reproductive part of a plant.
    • Fruits develop from flowers after pollination and contain the seeds of the plant.

    Flower Structure

    • Flowers consist of various components:
      • Petals: Brightly colored, scented structures that attract pollinators.
      • Sepals: Outermost green, leaf-like structures that protect the flower bud.
      • Stamens: Male reproductive parts consisting of anther and filament, which produce pollen.
      • Carpels/Pistils: Female reproductive parts consisting of stigma, style, and ovary, which holds the ovules (eggs).

    Pollination

    • Pollination is the transfer of pollen from the anther to the stigma.
    • Pollination is crucial for seed and fruit formation.
    • Pollination can occur within the same plant or between different plants.
    • Pollination agents include wind, water, birds, and insects.

    Seed Dispersal

    • Seed dispersal helps prevent competition for resources and enables plants to colonize new areas.
    • Seeds can be dispersed by wind, water, animals, or explosion.

    Seed Germination

    • Germination is the process of a seed developing into a young plant or seedling.
    • Seeds require warmth, air, water, and light to germinate.
    • Water softens the seed coat and helps it rupture.

    Life Cycle of a Flowering Plant

    • The life cycle of a flowering plant is a continuous cycle:
      • Seed germination
      • Growth of roots, stem, leaves, and flowers
      • Pollination
      • Seed production
      • Seed dispersal

    Plant Roles and Professions

    • Plants produce oxygen and food, sustaining life on Earth.
    • Insects and animals depend on plants for food and shelter.
    • Professions associated with plants include gardener, botanist, and farmer.
