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

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