Leaf: in the science of intentions is a member of the plant overhead allocated to the process of photosynthesis. For this purpose the Leaf will be generally flat and thin, to present the largest possible area and the largest amount of cells containing chlorophyll to sunlight and to allow the light of the burrow through the whole fabric of the Leaf. The Leaf also is responsible for respiration and transpiration and excretion. The Leaf can also be stored food and water and are subject to adjustments in certain types to achieve the purposes and functions appropriate to the surrounding environment.
Skin: a Mitrasap Plant cells and can accommodate at places of stomata, the leaf cover on both sides of the upper and lower, and is characterized by high skin being thicker than the skin so as to lower its exposure to continuous sunlight. Does not contain skin cells to green chloroplasts, the skin of the composite material Alkiotin which encapsulate the barrier layer which keeps the wax Leaf and protected in the days of intense heat and protect the Leaf from the loss of water.
And stomata are the spaces that exist in the skin surrounded by guard cells which have the ability to stretch and shrink according to temperature. In hot weather expands guard cells to close stomata and prevent water loss (through transpiration) of the plant, and vice versa in cold climates. Through the expansion and contraction are stomata balance the water level in the plant
Fabric of the Mediterranean: the skin located between the upper and foolish We have skin inside and Emadi tissue spongy tissue.
Emadi tissue: the cells of this rectangular fabric perpendicular regularly built of rows, containing a high proportion of green chloroplasts, and to do his part of the process of photosynthesis.
The spongy tissue: the cells of this tissue cells Broken irregular and there, including certain areas of this so-called spongy tissue containing cells to a small percentage of green chloroplasts, and the configuration of the ventilation function helps the process of photosynthesis.
Vascular tissue consists of: Wood: The transfer of food juices from places to places of manufacture, consumption and storage of bark: The transfer of water and salts from the roots to other parts of the plant in all directions is different from the form of Leaf from one type to another and sometimes within the same type.
Installation of the Leaf is different in the case of singlet falaqa binaries for monocotyledons. For the singlet monocotyledons, consisting of Leaf and the blade and sheath Oventinolcin
