Respiration in plants

WHAT IS RESPIRATION

 Each living cell in a plant as well as in an animal needs energy for driving various body activities. It is needed For building up proteins from amino acids, starch from glucose,and for various life activities

Every cell must release its own energy from glucose. The chemical process by which energy is released from glucose and other organic molecules is called respiration . As every cell derives energy from glucose,it must respire. Every cell in our body and in the living world respire.thus, respiration is biochemical decomposition of organic compound like simple carbohydrate,glucose,in the living cells with the release of energy.

What IS RESPIRATION EQUATION

The chemical reaction in which breakdown of glucose takes place during respiration can be represented as follows:

C6H12O6 +6O2  = 6CO2    +  6H2O +ENERGY

glucose   oxygen  carbon dioxide  WATER

The equation shows that energy is released when that energy is released when the glucose (sugar) is burned or oxidised in the respiration with the formation of carbon dioxide and water.

A flower is a specialised shoot in which leaves are modified into floral whorls. It is borne at the tip of stalk called pedicel or pedncle. The flowers with pedicel are called pedicellate flowers. Flowers without a pencil are called sessile flowers.sometimes,the pedicel may bear two small green, leaf like structure called bracteoles.         The the tip of a flower stalk expands into a Cup shaped fleshy swollen upper part called thalamus or receptacle. in it,nodes and internodes are highly condensed.
