Is it true that Unicellular organisms do not respire, only Multicellular organisms respire?

This isn't correct, because unicellular organisms also respire but in a different way from the animals.

Unicellular can’t do respiration the same as multicellular does, because of being so small, they do not have the organs, pores, and entryways to breathe like multicellular organisms.

Unicellular organisms do respiration by allowing oxygen to enter the cell membrane through the process of diffusion.

Diffusion is the process by which molecules from a high concentration region move to a low concentration region.
