| STANDARD B2: ORGANIZATION AND DEVELOPMENT OF LIVING SYSTEMS Students describe the general structure and function of cells. They can explain that all living systems are composed of cells and that organisms may be unicellular or multicellular. They understand that cells are composed of biological macromolecules and that the complex processes of the cell allow it to maintain a stable internal environment necessary to maintain life. They make predictions based on these understandings. |

| L2p1 Cells (prerequisite): All organisms are composed of cells, from just one cell to many cells. Water accounts for more than two-thirds of the weight of a cell, which gives cells many of their properties. In multicellular organisms, specialized cells perform specialized functions. Organs and organ systems are composed of cells and function to serve the needs of organisms for food, air, and waste removal. The way in which cells function is similar in all living organisms. | Amphibians and Reptiles - This event will test knowledge of amphibians,
turtles, crocodiles, and reptiles.
Anatomy - This event encompasses the anatomy of the nervous and circulatory
system and the effects of drugs and diseases on their health. |
| L2.p2 Cell Function (prerequisite): Cells carry out the many functions needed to sustain life. They grow and divide, thereby producing more cells. Food is used to provide energy for the work that cells do and is a source of the molecular building blocks from which needed materials are assembled. | Amphibians and Reptiles - This event will test knowledge of amphibians,
turtles, crocodiles, and reptiles.
Anatomy - This event encompasses the anatomy of the nervous and circulatory
system and the effects of drugs and diseases on their health. |
| L2.p3 Plants as Producers (prerequisite)Plants are producers; they use the energy from light to make sugar molecules from the atoms of carbon dioxide and water. Plants use these sugars, along with minerals from the soil, to form fats, proteins, and carbohydrates. This food can be used immediately, incorporated into the cells of a plant as the plant grows, or stored for later use. | Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes. |
| L2.p4 Animals as Consumers (prerequisite)All animals, including humans, are consumers; they obtain food by eating other organisms or their products. Consumers break down the structures of the organisms they eat to obtain the materials they need to grow and function. Decomposers, including bacteria and fungi, use dead organisms or their products for food. |
Amphibians and Reptiles - This event will test knowledge of amphibians, turtles, crocodiles, and reptiles. Disease Detectives - Students will use their investigative skills in the scientific study of disease, injury, health, and disability in populations or groups of people. There will be a focus on environmental causes of public health problems. Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes. |
| L2.p5 Common Elements (prerequisite)Living systems are made of complex molecules that consist mostly of a few elements, especially carbon, hydrogen, oxygen, nitrogen, and phosphorous. | Ecology - Students will answer questions involving content knowledge and process skills in the area of ecology and adaptation in featured biomes. |
