    Study Notes

    Plant Systems Overview

    • Plants are multicellular organisms, typically green due to chlorophyll, and immobile.
    • Flowering plants differ structurally from mosses, ferns, and conifers.
    • Plant systems are categorized into root and foliaceous (leaf) systems.
    • Plants produce their own food through photosynthesis.
    • Plants do not require complex systems like digestion, movement, or a nervous system.
    • Plants' essential functions include gas exchange and circulation.
    • Roots are usually below ground, absorbing majority of water and minerals.

    Root System

    • The root system anchors the plant, often extending extensively underground.
    • Roots absorb water and minerals.
    • Roots form a complex structure of dermal, fundamental, and vascular tissues to fulfill these roles.
    • Roots are a valuable food source, including carrots and sugar beets.

    Plant Tissues

    • Plant tissues include dermal, fundamental, and vascular tissues.
    • Dermal tissues form the outer layer and include epidermal and peridermal tissues.
    • Epidermal tissue is a thin outer layer covering non-woody parts.
    • Peridermal tissue forms bark on stems and roots.
    • Dermal tissues absorb water and minerals, create a waxy surface for protection, and produce defensive structures like hairs containing irritants.
    • Fundamental tissues perform various functions depending on location.
    • Vascular tissues (xylem and phloem) are responsible for transport.
      • Xylem transports water and minerals upwards.
      • Phloem transports sugars (glucose) and hormones throughout the plant.
    • Vascular tissues connect dermal and fundamental tissues, and store nutrients in roots and stems.

    Plant Growth

    • Plant growth involves apical and secondary meristems.
    • Apical meristems are regions of cell division, contributing to growth.
      • Elongation region: cells lengthen.
      • Maturation region: cells specialize into tissues.
    • Secondary meristems enable diameter growth.
    • Secondary merstems produce new layers of dermal tissue (cork), inner phloem, and inner xylem.

    Plant Parts and Their Roles

    • Plant parts include stems, roots, and leaves.
    • Leaves are the primary photosynthetic organs.
      • They use light energy, carbon dioxide, and water to produce glucose and oxygen.
      • Contain chloroplasts with thylakoids for photosynthesis.
    • Flowers are reproductive organs.
      • Contain male (pollen) and/or female (ovules) reproductive structures.
      • Fertilization leads to seed production within the fruit.
    • Stems support leaves, flowers, and transport substances between roots and leaves.

    Photosynthesis and Cellular Respiration

    • Photosynthesis: Plants use solar energy, water, and carbon dioxide to produce glucose and oxygen.
    • Cellular Respiration: Cells break down glucose in the presence of oxygen to create ATP (energy), releasing carbon dioxide and water as byproducts.
