ASU BIO 182: General Biology II
BIO 182 is the second half of ASU's majors biology sequence, shifting from BIO 181's cells and molecules to evolution, biodiversity, plant and animal structure and function, and ecology, with a required lab. Biology and pre-health tracks take it immediately after 181.

What makes it hard
The breadth flips: where 181 went deep on mechanisms, 182 sweeps across the entire living world, and the biodiversity material is a memorization mountain stacked on top of conceptual evolution questions. Exams mix recall of organism groups with application questions about selection and ecology, so neither pure memorization nor pure concept-study covers the whole grade.
What you'll cover
- • Evolution and natural selection
- • Phylogenetics and the tree of life
- • Diversity of life
- • Plant structure and function
- • Animal physiology basics
- • Ecology and ecosystems
The BIO 182 study guide
How to study for ASU BIO 182, step by step.
- 1
Learn evolution as the organizing logic
Selection, drift, and phylogeny are the framework every other BIO 182 unit hangs on. Get genuinely fluent reading and building phylogenetic trees early, since tree questions are an exam fixture.
- 2
Start the biodiversity memorization in week one
Organism groups, their traits, and their relationships are pure accumulation that cramming can't compress. A small daily flashcard habit from the start turns the mountain into a slope.
- 3
Practice application questions on selection scenarios
Exams present novel scenarios (a population, a pressure, a change) and ask what evolution predicts. Practice reasoning through these rather than reciting definitions of fitness.
- 4
Tie plant and animal units to function
Structures stick when attached to what they solve: transport, gas exchange, reproduction. 'What problem does this anatomy solve?' is both the best memory hook and the exam's favorite angle.
- 5
Keep lab on its own calendar track
The required lab runs parallel deadlines all semester. Draft each report right after the session so lab work never competes with exam prep for the same nights.

FAQ
Is BIO 182 harder than BIO 181?
Different hard: 181 is deep mechanisms, 182 is enormous breadth. Students who liked molecular detail often find 182's memorization load heavier; students who struggled with biochemistry often find 182 friendlier. Both reward spaced review over cramming.
What does BIO 182 cover at ASU?
Evolution and natural selection, phylogenetics, the diversity of life across major organism groups, plant and animal structure and function, and ecology, with a required lab running parallel all semester.
Do I need BIO 181 before BIO 182?
That's the standard order for ASU's majors sequence, and pre-health tracks expect both. Some genetics and cell concepts from 181 resurface in 182's evolution units, so take them in sequence when possible.
More ASU courses
BIO 181: General Biology I
BIO 181 is the first majors-level biology course at ASU, covering cell biology, biochemistry basics, genetics, and molecular biology with a required lab. It's the gateway for biology, biomedical, and pre-health students, and a course where intro-level expectations meet real scientific depth.
MIC 205: Microbiology
MIC 205 is ASU's general microbiology course covering microbial cell structure, metabolism, microbial genetics, immunology, and infectious disease. It's required for nursing and many pre-health paths, usually taken with the separate MIC 206 lab, and it runs steadily on campus and through ASU Online.
