Transport in plants is internal movement of water, minerals, oxygen and carbon dioxide inside the plant body. The movement of these substances are effected by biological methods, physical methods or chemical methods. In this post we are going to discuss some most important questions and answers which are based on Long Distance Transport of Water.
