Leaf Mosaic.•Enable leaves to receive as much light
as possible.
•Plant can also detect the direction of the light so that their leaves are always held in the best position to absorb maximum
amount of light.
•A leaf consist of a flat, thin lamina which is joined to the stem by a petiole holds
the leaf in the best position to receive the maximum amount of light. From the
petiole, a main vein leads down the leaf and branches out into side veins which
support the lamina.

Xylem and phloem
• Xylem transport water absorbed by the roots to the leaf.
• Phloem transport organic product of photosynthesis away from thr leaf
Xylem transport water absorbed by the roots to the leaf.
Phloem transport organic product of photosynthesis away from the leaf.
• The epidermis of a leaf has a tiny pores called stomata
• Found abundantly on the lower surface of the leaf.
• Flanked by 2 guard cells which regulate the size of the pores.
• Support photosynthesis,allowing the exchange of gases between the internal part of the leaf and the environment.
• Carbon dioxide diffuse into the leaf through stomata,and oxygen , as a by product of photosynthesis diffuse out of the leaf via the same route
