How to Answer AP Biology FRQ

Free Response Questions in AP Biology

Free Response Questions (FRQs)

The section of the AP Biology exam where students write extended answers to demonstrate knowledge and reasoning.

Long FRQs

Two long questions worth 8–10 points each, requiring detailed explanations, data analysis, and graph construction.

Short FRQs

Four questions worth 4 points each, focused on concise answers to targeted prompts

Task Verbs

A word indicating what the question expects (e.g., "Explain," "Describe," "Justify").

Identify

State facts directly without explanation (e.g., "Identify the organelle responsible for photosynthesis: chloroplast").

Define

Provide the meaning of a term, often requiring examples or context.

Explain

Explain how or why a biological process or outcome occurs.

Justify

Include evidence or reasoning to support a claim, often using data.

Predict

Predict an outcome based on biological principles or data trends.

Data Analysis

 The process of extracting key trends or patterns from graphs or data tables.

Construct/Draw

Create and label visual representations such as graphs or models, following conventions

Independent Variable

The variable manipulated in an experiment (e.g., light intensity in a photosynthesis lab).

Dependent Variable

The variable measured to observe the effects of changes (e.g., rate of photosynthesis).

Controlled Variables

Variables kept constant to ensure reliable experimental results (e.g., temperature).

Osmosis

A biological concept where osmosis balances solute concentrations across membranes

Light-Dependent Reactions

The process that converts light energy into chemical energy via photosynthesis

Oxidative Phosphorylation

The process by which ATP is produced during cellular respiration in mitochondria.

Logistic Growth Curve

A visual representation of population growth under limited resources

Semi-Conservative Replication

The hypothesis stating that DNA replication is semi-conservative, proven by the Meselson-Stahl experiment.

Concise Answer

Writing your final answer clearly with minimal filler, directly addressing the task

Proper Graph Components

A graph where axes are labeled with variables, units, and a descriptive title

Structured Responses

A skill involving organizing your response in labeled sections (e.g., part a, b, c).

Proofreading

The process of revisiting your written work to correct terminology or incomplete ideas

Irrelevant Details

The deliberate inclusion of irrelevant information that may detract from a focused response

FRQ Practice

Practicing past exam FRQs under timed conditions to simulate test-day environments.
