- - - - allows photosynthesis deeper in leaf
- - - - has many leaflets
      - attached to petiolule by rachis
      - rachis=extension of petiole
      - advangs. of comp. leaves:
        
        leaflets flex in wind
        
        more turbulence around leaflets
        
        disease spread slower
- - - - spongy mesophyll
        
        in lower portion of leaf
        
        lets CO2 quickly diffuse away from stomata
    - - in mesophyll
      - main photosynthetic tiss. of most plants
- - - - veins=bundles of vasc.tiss
        
        eudicot veins=netted pattern of reticulate venation
        
        monocot leaves=long&strap shaped
        
        monocot leaves=parallel venation
