If sensing and responding to change is one of the criteria for life, does a one-celled human meet that criterion?

The remarkable thing about cells is that each one, in whatever phase of life it may be, is equipped with receptors on its cell membrane that can indeed sense and respond to its environment. In fact, the reason that the first cells of a human continue to multiply and grow is because of the miraculous simulous and response interaction between the protein receptors on the cell membrane of the Zygote and its environment. A newly-conceived human absolutely meets the third criterion for life.
