The correct answers are as follows:
1. Diffusion of water across a membrane from areas of higher concentration to areas of lower concentration is called OSMOSIS. Osmosis is a very important process in the living organisms because the process facilitates the even distribution of essential nutrients in the cells of the body. Osmosis also facilitate the removal of waste products from the living cells.
2. The cell mechanism of active transport involves the transport of insoluble chemicals across the THE PLASMA MEMBRANE OF CELLS.
In living cells, there are two basic types of particles' transportation for movement of particles in an out of the cells, these are passive and active transport. The passive mode of transportation does not require energy to transport particles but active transport requires the supply of energy in form of ATP to transport particles in and out of the cells.
