In what ways can various substances penetrate into the cell?

Various substances can enter the cell through special pores that are located on the cell membrane. Different cells can be connected using these pores to each other. This is how the metabolism takes place in the tissues of the body. Also, the cell can receive various substances through diffusion. In this case, various substances that are dissolved in water enter the cell without the help of pores, but pass through the membrane. It all depends on the type of cell, its structure, location in the body and the function of the cell.
