Naming Organisms 4. Naming organisms A. Common names are those given in your language and are often confusing or overlapping B. Scientific names are those given in Latin which describes only one organism – no confusion

Animal Kingdom 1. Animals are made of many cells. Different kinds of cells carry out different functions such as sensing the environment, getting rid of wastes, and reproducing. 2. Animal cells have a nucleus and specialized structures inside the cells called organelles. 3. Animals depend on other living things in the environment for food. Some eat plants, some eat other animals, and some eat plants and animals.

Animal Kingdom 4. Animals digest their food. The proteins, carbohydrates, and fats in foods are broken down into simpler molecules that can move into the animal’s cells. 5. Many animals move from place to place. They can escape from their enemies and find food, mates, and places to live. Animals that move slowly or not at all have adaptations that make it possible for them to take care of these needs in other ways. 6. All animals are capable of reproducing sexually. Some animals also can reproduce asexually.
