The smallest creatures have only one, yet they’re as alive as you are. What exactly is a cell? In plain and simple terms, it’s the smallest living piece of an organism — including you. Without cells, you’d be a disorganized blob of chemicals that’d just ooze out into the environment. And that is why the cell is the fundamental unit of life. You get to explore the purpose and structure of cells in this chapter. And because cells rely on chemical reactions to make things happen, you also find out all about enzymes, which are proteins that help speed up the pace of chemical reactions. An Overview of Cells Cells are sacs of fluid that are reinforced by proteins and surrounded by membranes. Inside the fluid float chemicals and organelles, structures insi...
