The Mitochondria is an organelle (specialized substructure within a cell) that is most often described as the “power house” of a cell. Mitochondria are very small organelles that have two membranes, an outer smooth membrane and an inner folded membrane. The folds in the inner membrane are called the cristea.

There are many ways that objects and items in our world are classified. When objects are classified they are placed into a group based on similar characteristics. For example animals can be classified into a number of different groups such as mammals, birds, amphibians, reptiles and fish. Each group has a set of indicators that help us to determine which group an animal belongs in. For example, mammals are warm-blooded animals that give birth to live young and feed them with breast milk. This makes it easy to place both a dog and a whale in the mammal classification. Another way that we broadly classify objects is to use indicators to decide if an object is animate or inanimate.
