Most leaves are broad and so have a large surface area allowing them to absrob more light
1 of 11
A thin shape:
A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out eaily.
2 of 11
Chlorophyll:
This chemical gives the leaves their green color and transfers light energy to chemical energy.
3 of 11
Veins:
Networks of viens support he structure of the leaf and transport substances to and from the cells in the leaf.
4 of 11
Stomata:
These are small holes on the underside of the leaf that allow gases to diffuse in and out.
5 of 11
Cuticle-(waterproof):
The cuticle is a waxy, waerproof layer which cuts down on the water lost by evaporation and protects againsts parasitic fungi.
6 of 11
Upper Epidermis-(Transparent):
A single layer of cells that are transparent and contain no chloroplast allowing light o pass straight through.
7 of 11
palisade layer-(contains chloroplast):
This layer is make of palisade cells which contains chloroplasts. his is where most of the photosynthesis takes place.
8 of 11
Vein:
The vein contains tubes called the xylem and phloem.The xylem brings water and salts to the leaf for photosynthesis. The phloem transports the dissolved food away.
9 of 11
Spongy Layer-(irregularly shaped cells with air spaces between hem.)
This layer consists of irregularly shaped cells with large air spaces between hem allowing gas exchanges (diffusion) between stomata and photosynthesis cells.
10 of 11
Lower epidermis-(Contains lots of tiny):
This layer contains lots of tiny holes or pores called stomata a regular intervals. These allow gases o diffuse in and out of he leaf.
