  1. Topic 9 : Plant Science Topic 9.1 Plant Structure and Gowth

  2. Draw and label plan diagrams to show the distribution of tissues in the stem and leaf of a dicotyledonous plant

  3. Outline 3 differences between the structures of dicotyledons and monocotyledons

  4. Explain the relationship btw the distribution of tissues in the dicot leaf, and their functions • Functions: Absorption of light • Gas exchange • Support

  5. Identify modifications to roots, stems, and leaves for different functions: bulbs, stems tubers, storage roots, and tendrils

  6. State that dicots have apical (primary) and lateral (secondary/cambium) meristems • Meristems/meristematic regions of plants are mitotically active –

  7. Lateral meristems

  8. Explain the role of auxin (a plant hormone) as an example of the control of plant growth
