the diagram below shows the same type of molecules in area a and area b. with the passage of time, some molecules move from area a to area b. this movement is the result of which process?
The movement of molecules from area A to area B is as a result of
Diffusion
Movement of molecules
The molecules are moving from high concentration to areas of lower concentrations. Hence it is called diffusion. Even though there is semi permeable membrane, the molecules are not moving against their concentration gradient.
Definition of terms
The term phagocytosis stands for uptake of solid food particles by cell; pinocytosis is the uptake of liquid material into the cell; cyclosis refers to streaming of cytoplasm in the cell.
