LS1.A Structure and Function


K-2 All organisms have external parts that they use to perform daily functions.
3-5 Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.
6-8 All living things are made up of cells. In organisms, cells work together to form
tissues and organs that are specialized for particular body functions.
9-12 Systems of specialized cells within organisms help perform essential functions of life. Any one system in an organism is made up of numerous parts. Feedback mechanisms maintain an organism’s internal conditions within certain limits and mediate behaviors.

LS1.D Information Processing
K-2 Animals sense and communicate information and respond to inputs with behaviors that help them grow and survive.
3-5 Different sense receptors are specialized for particular kinds of information; Animals use their perceptions and memories to guide their actions.
6-8 Each sense receptor responds to different inputs, transmitting them as signals that travel along nerve cells to the brain; The signals are then processed in the brain, resulting in immediate behavior or memories.
