    Study Notes

    Plant Reproduction

    • Plants differ from animals in that they cannot move.
    • Plants have chlorophyll to make food.
    • Plant parts like roots, stems, and leaves have specific functions.

    Plant Structure

    • Roots:
      • Roots anchor plants to the ground.
      • Roots absorb water and dissolved nutrients from the soil.
      • Taproot system: Has a large primary root with secondary and tertiary roots, reaching deeper water sources.
      • Fibrous root system: Has many small roots spreading near the surface, absorbing water readily.
      • Inside the roots are tube-like structures (bundles)
        • Xylem tissue: Transports water and dissolved minerals.
        • Phloem tissue: Transports sugar from leaves to other plant parts.
    • Stems:
      • Support the plant.
    • Leaves:
      • Produce food for the plant.
