Unit 1 Cell Biology

Unit Introduction 
Welcome to the Cell Biology Unit of National 4 Biology. In this unit we start by thinking about the very small building block that make up all living things - cells. These simple building blocks make up every living thing from tiny bacteria, to enormous trees to complex thinking living things like ourselves. We will think about how cells make more of themselves, how a whole organism is coded for by our DNA and then finish with some of the important chemical reactions which are essential to life and how they are controlled.
