A student claims that, according to cell theory, the cell is the basic unit of life, and all cells are created spontaneously. Is this student correct?(1 point)
Responses
No, the student is not correct because the basic unit of life is within a cell.

Yes, the student is correct because all cells are created spontaneously.
Yes, the student is correct because all cells are created spontaneously.
The correct response is:
No, the student is not correct because all cells come from preexisting cells.
According to cell theory, one of the fundamental principles is that all living cells arise from preexisting cells, which means cells are not created spontaneously.
