Nitrates enter the cell through the process of active transport. Nitrates are essential for development of leaves of a plant and are absorbed through root hair cells.
the process that causes the water to enter and leave the cell is diffusion
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.

Endocytosis
receptor-mediated endocytosis.

i am the most awesome person in the world
The process of bringing large undissolved particles into a cell would be phagocytosis, literally "cell eating." Hope that helps! :)
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
