us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities. Bacterial cells are so small that scientists measure them in units called micrometers

Tissues, Cells and Organs The human body consists of many millions of cells. The cell is the basic structural unit of the body. A typical body cell has the following features; A cell membrane – this acts as a boundary for the cell contents. It also acts as a barrier, allowing certain substances into the cell, while keeping other substances out. The cell membrane is said to be ‘selectively permeable’. A nucleus – this determines what type of cell it will be, e.g. liver cell, nerve cell, skin
