What I will learn?

• Whether you are investigating a plant or animal system, multicellular organisms are all organized the same way.
• Body systems can be broken down into components called organs
• Organs are made of different kinds of tissue, and tissue is made from groups of specialized cells.
• Animals rely on several different systems to survive.
• These systems work together to allow blood to flow, eat and digest food, and move around.
• Some of the major systems in animals are nervous, digestive, circulatory, respiratory, excretory, muscular, and skeletal.
• But some animals, like humans, also have other smaller systems that help them too.
• Plants rely on systems to survive.
• These systems work together to allow the plant to make food, to allow water to travel throughout the plant, and to help the plant reproduce.
• Plants also have organs such as roots, stems, and leaves.
• But unlike animals, plants have only two major systems: the root system and the shoot system.
• Systems depend on each other to function normally.
• For example, the respiratory system brings oxygen into the body, and the circulatory system moves oxygen throughout the body.
• When systems work together like they should, plants and animals are able to grow and reproduce.
• If one system is not functioning normally, it can affect other systems.
• For example, wearing a cast to heal a broken bone will affect how you can use your muscles.
