What Do You Know About Passive Transport? Quiz
Settings
The cell is the basic building block for human beings and that being said for any substance to move within the body, it has to pass through the cell membranes. Have you just finished chapter five of section one in biology class? Take up this test and get to see just how much you got to understand about passive transport. All the best!
