Answer:
The correct answer is False
Specialised cells mean they have one specific job, for example cells in the alveoli (in the lungs) would be specialised to transfer oxygen into the blood. An unspecialised cell would be an embryonic stem cell which can become any cell to suit the needs of the organism, which is how a small cluster of cells in a zygote becomes a full human with all the organs and such.
they make oxygen and so we don't die from too much oxygen
