When greenhouse growing first began in the 13th century, it served as a way to appease royalty’s nutritional demands, house foreign tropical plants for study, and grow medicinal plants. Commonly found among the wealthy class citizens, eventually the science of greenhouse growing expanded to universities where research could be continued and eventually published. Today, with the surge of new and innovative technology within the agriculture industry, operating a greenhouse isn’t limited to just the wealthy and universities, but to anyone with a desire to start their own business or even just to incorporate new methods of sustainable living into their everyday lives. Before you decide that greenhouse growing is the next step for your lifestyle, careful planning and research must be taken into consideration to effectively weigh the advantages and disadvantages to greenhouse growing.

Function of RBC
The main function of Red blood Cells (R B C) are to carry oxygen to all parts of the body and to bring carbon dioxide to the lungs. The haemoglobin in the red blood cell is the carrier for oxygen and carbon dioxide. So, for the transportation of oxygen and Carbon dioxide, adequate number of matured and functioning red blood cells must be available. RBC must also contain appropriate amount of haemoglobin.
Function of WBC:
(WBC) are chiefly responsible for fighting infection by identifying, engulfing, and destroying foreign organisms . They are active in the immune response by producing antibodies to foreign organisms.
Function of Platetets:
platelets plays a key role in the haemostatic reactions that prevent bleeding after minimal injury to blood vessels. Without an adequate number of functioning platelets, an individual would bleed to death.

Respiration: The biological process in which food is utilized to produce energy is called respiration. Respiration is necessary for survival of the living beings. A living being cannot survive even for a few seconds, without respiration. During respiration, it is mainly the carbohydrate which is oxidized to produce energy. This can be shown by following equation:
Carbohydrate + Oxygen → Carbon dioxide + Water + Energy
C6H12O6 + 6O2 → 6CO2 + 6H2 + Energy

Examples of convection are wind currents, the lower floor of a building is cooler than the upper floor, and water is warmer at the surface of a swimming pool or lake. Due to convection, the atmosphere at the sea shore is always pleasant.
