For each pair of terms explain how the meanings of the terms differ. 1. diffusion and osmosis 2. active transport and passive transport 3. endocytosis and exocytosis

1) Diffusion and osmosis 
the diffusion of water through a semipermeable membrane is osmosis and the movement of particles from regions of higher density to regions of lower density is diffusion
2)The passive transport does not require energy and the active transport does ,this is what makes them different 
3)Endocytosis is a process for moving items that are outside of the cell into the cytoplasm of the cell. Exocytosis is a process for moving items from the cytoplasm of the cell to the outside.
