Draw and label plan diagrams to show the distribution of tissues in the stem
and leaf of a dicotyledonous plant
Outline 3 differences between the structures of dicotyledons and monocotyledons
Explain the relationship btw the distribution of tissues in the dicot leaf, and their functions
• Functions: Absorption of light
• Gas exchange
• Support
Identify modifications to roots, stems, and leaves for different functions: bulbs, stems tubers, storage roots, and tendrils
State that dicots have apical (primary) and lateral (secondary/cambium) meristems
• Meristems/meristematic regions of plants are mitotically active –
Lateral meristems
Explain the role of auxin (a plant hormone) as an example of the control of plant growth
