The Big Ideas of AP® Biology

There are four big ideas in the course:

  • Big Idea 1: Evolution – The process of evolution drives the diversity and unity of life.
  • Big Idea 2: Energetics – Biological systems use energy and molecular building blocks to grow, reproduce, and maintain dynamic homeostasis.
  • Big Idea 3: Information Storage and Transmission – Living systems store, retrieve, transmit, and respond to information essential to life processes.
  • Big Idea 4: Systems Interactions – Biological systems interact, and these systems and their interactions exhibit complex properties.

AP® Biology Practice Tests Sorted by Big Ideas & Enduring Understandings

One of the best parts about using Albert for your AP® Biology review is that each practice question is tied directly back to the College Board standard, enduring understanding, or essential knowledge that’s being evaluated.

We’ve gone ahead and filtered down our AP® Bio multiple choice practice questions to help you get a head start:

Big Idea 1: Evolution

  • EVO-1:Evolution is characterized by a change in the genetic makeup of a population over time and is supported by multiple lines of evidence
  • EVO-2: Organisms are linked by lines of descent from common ancestry.
  • EVO-3: Life continues to evolve within a changing environment.

Big Idea 2: Energetics

  • ENE-1: The highly complex organization of living systems requires constant input of energy and the exchange of macromolecules.
  • ENE-2: Cells have membranes that allow them to establish and maintain internal environments that are different from their external environments.
  • ENE-3: Timing and coordination of biological mechanisms involved in growth, reproduction, and homeostasis depend on organisms responding to environmental cues.
  • ENE-4: Communities and ecosystems change on the basis of interactions among populations and disruptions to the environment.

Big Idea 3: Information Storage and Transmission

  • IST-1: Heritable information provides for continuity of life.
  • IST-2: Differences in the expression of genes account for some of the phenotypic differences between organisms.
  • IST-3: Cells communicate by generating, transmitting, receiving, and responding to chemical signals.
  • IST-4: The processing of genetic information is imperfect and is a source of genetic variation.
  • IST-5: Transmission of information results in changes within and between biological systems.

Big Idea 4: Systems Interactions

  • SYI-1: Living systems are organized in a hierarchy of structural levels that interact.
  • SYI-2: Competition and cooperation are important aspects of biological systems.
  • SYI-3: Naturally occurring diversity among and between components within biological systems affects interactions with the environment.
