Leaves, tendrils-of-a-climber , bud scales , leaf veins , Monocots have…

- - - - layer just below the epidermis
  - - - similar to foliage leaves
      - lamina is tubular rather than flat
        
        secretes watery digestive fluid
      - contains numerous trichomes
    - - upper surface covered with trichomes
        
        secrete sticky digestive liquid
    - - midrib motor cells lose water quickly
      - closes two halves of lamina move upward
      - digests insects then opens again
- - - - leaf flat and wide for maximum CO2 absorption
      - leaf blade
        
        light harvesting portion
        
        dorsal surface
        
        ventral surface
      - petiole
        
        stalk of leaf
        
        allows fluttering in wind (cools leaf)
  - - - instead protective corky layer
  - - - blade of one part
    - - blade divided into several parts
      - leaflets attached by petiolule
        
        rachis
      - more carbon dioxide
  - - - netted pattern called reticulate venation
  - - - cuts off the leaf when its useful life is over
      - leaf scar
- - - - photosynthetic tissue
  - - - midrib (midvein)
        
        lateral veins emerge
        
        minor veins
        
        releasing water from xylem and loading sugar into phloem
        
        conduct and support the leaf blade
    - - bundle sheath extension
  - - - protect the shoot apical meristem
- - - - bulk of midrib
  - - - outer surface abaxial epidermis
      - inner surface is adaxial epidermis
- - - - elevate leaves, conduct stuff to and fro
      - must die to be functional
    - - primary tissue
      - thin and flat for absorption of light
      - alive and chlorophyll rich chlorenchyma
