There are thousands of different kinds of microbes. Microbes called bacteria are the smallest living things. Bacteria live almost everywhere: on land, in water, and even inside you. Some microscopic life forms are like plants. Tiny diatoms are microbes that live in lakes and the ocean. Diatoms soak up sunlight and use its energy to make food, just like plants.

Some microscopic life forms are more like animals. Protozoa such as the amoeba and paramecium are animal-like microorganisms. An amoeba can move by changing the shape of its body. It sticks out a pseudo pod, or false foot. A paramecium is covered with tiny hairs. It waves its hairs rapidly to swim.

Viruses are another kind of microbe. Viruses sometimes act like living things and other times act like nonliving things. Viruses sometimes live in the cells of plants and animals. Inside a cell, a virus reproduces like a living thing. The virus uses the cell to make many copies of itself. Viruses are too small to see with an ordinary microscope. You need a powerful electron microscope to see a virus. Outside of a plant or animal cell, a virus is like a nonliving thing.

What helps a paramecium swim?
