processes involved in transport

>The proteins present in the membrane may function as carriers or receptors or enzymes. Transport across membranes involves several mechanisms. There are processes like diffusion and osmosis, which do not require energy or activity of the cell. Diffusion involvesh..

In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transpo..

It takes places within the cells of an organism. biochemical processes involved in respiration break down the substate to release energy in the tissues within the cells of the organism. Thus it is called cellular respiration. Gaseous exchange in plants takes place through t..

It is the vascular tissue that transports water across the plant body. Xylem is made up of four different types of cells. They are tracheids, vessels, xylem fibres and xylem parenchyma. Of these only tracheids and vessels are involved in the transport of water and min..
