problem of air transportation

Food is manufactured in the form of carbohydrates (sucrose) in the leaves. Thus, food is transported as sucrose along phloem. From the leaves the prepared food has to be transported to the roots, the younger top regions of the plant, the flowers and fruits. Thus, the food has..

Oxygen Transport - Oxygen is transported in a combined state. The haemoglobin pigment (Hb) has an affinity for oxygen. In the lungs, it combines with oxygen and forms HbO 2 , oxyhaemoglobi..

Ascent of Sap - Transport of Water - Plants absorb water from the soil through the roots. Thus, water has to be transported upwards to the other parts of the plant. This upward movement of water is called ascent of sap . It is called the sap as it contains many dissolved mineral..

Electron transport chain refers to the light driven reactions of photosynthesis. They were first formulated in 1939 by Robert Hill. The two photosystems are connected in series with each other by the components of electron transport system. The reaction centres become so excited..

Importance of Studying Transportation - Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of ..
