Biology Basics

• Identify cell structures and their functions.
• Connect cells to tissues, organs, organ systems, and organisms.

Practice: Label a cell model and explain how three structures help the cell stay alive.

• Explain how body systems interact to meet organism needs.
• Use cause-effect language for feedback and regulation.

Practice: Trace how the respiratory, circulatory, and digestive systems work together during exercise.

• Use genes, chromosomes, inherited traits, and variation accurately.
• Interpret simple inheritance and trait-data patterns.

Practice: Analyze a family-trait scenario and write a CER paragraph about inheritance.

• Model producers, consumers, decomposers, populations, and communities.
• Explain energy flow and matter cycling in ecosystems.

Practice: Build a food-web model and predict what changes when one population decreases.
