Missouri:
6-8 LS1.A1 Provide evidence that organisms are made of cells and that a single cell must carry out all of the basic functions of life.
6-8 LS1.A2 Develop and use a model to describe the function of a cell asa whole and ways parts of the cells contribute to that function.
6-8 LS1.A3 Develop an argument supported by evidence for how multicellular organisms are organized by varying levels of complexity; cells, tissue, organs, organ systems.
6-8 LS1.A4 Present evidence that body systems interact to carry out key body functions, including providing nutrients and oxygen to cells, removing carbon dioxide and waste from cells and the body, controlling body motion/activity and coordination, and protecting the body.
Arizona:
7.L1U1.8 Obtain, evaluate, and communicate information to provide evidence that all living things are made of cells, cells come from existing cells, and cells are the basic structural and functional unit of all living things.
7.L1U1.9 Construct an explanation to demonstrate the relationship between major cell structures and cell functions (plant and animal).
7.L1U1.10 Develop and use a model to explain how cells, tissues, and organ systems maintain life (animals).
