2. Describe the permeability of cell membranes. How to substances cross cellmembranes? Utilize the terms bi-polar, semi-permeabl
e, diffusion, active transport, membrane proteins, endocytosis, exocytosis, vesicles, phagocytosis, pinocytosis, etc. (This should be 3-4paragraphs long)
The permeability of a cell membrane simply means the ability of the cell membrane to allow solutes and solventsdiffuse or pass through it
In biology, substances moves in and out of cells through semi-permeable membranes of the cell in a function of different metabolic processes such as:
Osmosis: This is the movement of substances from a region of low concentration to a region of highconcentration
Diffusion: This is the movement of substances from a region of high concentration to a region of lowconcentration
Phagocytosis: This involves the movement of substances through phagocytic bacteria
Endocytosis: This involves the movement of substances into the cell
Exocytosis: This involves the movement of substances outside the cell environment
Pinocytosis and others
So therefore, thee permeability of a cell membrane simply means the ability of the cell membrane to allow solutes and solventsdiffuse or pass through it

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
