The Leaf
ADAPTIONS
Absorb Sunlight
-
large surface area
- held perpendicular to sun
- max area exposed
thin
- allow greater light penetration
transparent cuticle + epidermis
- allow light penetrate to palisade cells
- where chloroplasts are for PS
palisade mesophyll cells...
- packed with chloroplasts
- long axis of cell perpendicular to surface
- so more fitted in
- less light absorbed by cell wall
chloroplasts can move
- arrange themselves best
position for LA
chlorophyll molecules inside chloroplasts...
- held ordered arrangement
- on membrane within grana
- presents max amount chlorophyll to light
- brings it into close proximity of other pigments
xylem tissue supports leaf
- max SA presented to light
-
