Answer:
Excretion: The process of removing materials which are no longer useful in the body.
The unicellular organisms perform excretion via the cell membrane with the help of the process of diffusion.
Diffusion: Process in which a substance gets transported from a region where it is present in high concentration to a place where it is present in low concentration.
It is similar to the process of osmosis in which the molecules present in a solvent move to the region of low concentration via a semipermeable membrane.
