Electron Chain
active transport
osmosis, diffusion, and active transport
Exocytosis is the process by which the cell directs the contents of secretory vesicles out of the cell membrane. This process occurs through the fusion of the vacuole membrane with the cell membrane.
it occurs in the cell membrane(through the cell membrane really)
The process you are talking of is referred to as 'endocytosis', which is bulk transport into the cell.
penetration
The cell membrane enables a cell to control what enters and leaves. The membrane has a selective semi-permeable membrane which facilitate this process.

advantage of membrane cell
Diffusion occurs on the cell membrane.
If substances did not pass through cell membranes, then all single-celled and multicellular organisms would die.

penetration
The cell membrane enables a cell to control what enters and leaves. The membrane has a selective semi-permeable membrane which facilitate this process.
Endocytosis is the process of a cell 'engulfing' material by foldings of the cell membrane.
the membrane cell process , the diaphragm cell process and the mercury cell process
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
