One is not considered a Prime number, because a normal prime number only has two divisors, itself and one. But one only has one divisor- one and itself, which is also one. One is a special case, not prime, not composite.
No, it is the multiplicative identity and neither prime or composite. There was a short period in history when some called it prime--but those years are long gone.

No prime number can be a perfect square True or false?
True. By definition, a prime number is divisible by one and by itself. Also by definition, a perfect square has at least an additional pair of factors - it's square root. Therefore a prime number could never be a perfect square. One exception that might come to mind in this case is the number one. One however, is not considered a prime number, and thus does not conflict with this rule.
