Sample BW Abitur Biology Bilingual EN Practice Questions

Try these sample questions to review concepts for the BW Abitur Biology Bilingual EN exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a typical eukaryotic animal cell, where is most chromosomal DNA stored?
A.Ribosome
B.Nucleus
C.Lysosome
D.Centriole
Explanation: The nucleus houses the chromosomes of a typical eukaryotic animal cell and is the main site of DNA storage and transcription.
2What is the primary role of mitochondria in aerobic eukaryotic cells?
A.Synthesize most ATP via cellular respiration
B.Package secretory proteins
C.Digest foreign DNA only
D.Store starch as amyloplasts
Explanation: Mitochondria carry out key steps of aerobic respiration, including the citric acid cycle and oxidative phosphorylation, producing most cellular ATP.
3Why do phospholipids spontaneously form bilayers in water?
A.They have hydrophilic heads and hydrophobic tails
B.Both ends are equally hydrophilic
C.They covalently polymerize into rigid sheets
D.They contain cellulose microfibrils
Explanation: Phospholipids are amphipathic: polar heads interact with water while nonpolar fatty-acid tails face inward, stabilizing a bilayer.
4A plant cell is placed in a strongly hypertonic solution. What happens first by osmosis?
A.Water enters and turgor rises
B.Water leaves and the vacuole shrinks
C.Solute floods into the nucleus
D.The cell wall dissolves instantly
Explanation: Water moves from higher water potential inside the cell toward the more concentrated external solution, so the vacuole and protoplast shrink (plasmolysis risk).
5Which organelle is the main site of photosynthesis in green plant cells?
A.Chloroplast
B.Mitochondrion
C.Golgi apparatus
D.Peroxisome only
Explanation: Chloroplasts contain chlorophyll and thylakoid membranes where light reactions occur, making them the main photosynthetic organelles.
6What is the direct function of ribosomes?
A.Synthesize proteins from mRNA instructions
B.Pump blood through capillaries
C.Separate homologous chromosomes
D.Fix atmospheric N2 into ammonia
Explanation: Ribosomes translate mRNA codons and join amino acids into polypeptides.
7Which reactants are directly used in oxygenic photosynthesis?
A.Glucose and oxygen
B.Carbon dioxide and water
C.Lactate and ethanol
D.ATP and oxygen only as carbon sources
Explanation: Oxygenic photosynthesis uses CO2 and H2O (with light energy) to produce carbohydrate and O2.
8In aerobic respiration, where does oxygen act as the final electron acceptor?
A.Glycolysis
B.Calvin cycle
C.Electron transport chain
D.DNA replication
Explanation: Oxygen accepts electrons at the end of the mitochondrial electron transport chain and combines with protons to form water.
9What usually happens to enzyme activity far above the enzyme's optimum temperature?
A.The active site may denature and activity falls
B.The enzyme becomes a carbohydrate
C.Activation energy becomes zero
D.The substrate turns into the enzyme
Explanation: Excessive heat can denature proteins, distorting the active site so substrate binding and catalysis decline.
10In double-stranded DNA, which base pairs with adenine?
A.Guanine
B.Cytosine
C.Thymine
D.Uracil
Explanation: In DNA, adenine pairs with thymine via hydrogen bonds; guanine pairs with cytosine.

About the BW Abitur Biology Bilingual EN Exam

Baden-Württemberg Biologie bilingual englisch is the English-medium written Abitur Biology assessment for the bilingual / Internationales Abitur Baden-Württemberg pathway. Content follows Bildungsplan 2016 Biologie (V2) Oberstufe themes—biomolecules and molecular genetics, Stoff- und Energieumwandlung, evolution, ecology, neurobiology and hormones, applied biology, and immune biology—assessed with bilingual operators and English scientific terminology. Official papers emphasize material analysis, experimental evidence, and constructed English responses rather than multiple choice. This free bank trains concept recognition, data reasoning, and operator-aligned judgment in English before students practice full official-style tasks.

Exam sponsor: Kultusministerium Baden-Württemberg (Ministry of Education, Youth and Sports); IBBW supports statewide Abitur task and correction materials. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official written Biologie bilingual englisch is a material-based constructed-response and analysis examination in English under the Internationales Abitur Baden-Württemberg / bilingual pathway. Per Fächerlass Biology rules mirrored for the bilingual paper, candidates typically receive four tasks and work three. Responses use the Operatorengrundstock Biologie bilingual (English operator translations such as describe, analyze, interpret, evaluate, plan). Korrekturrichtlinien section IX additionally addresses language accuracy and answers in German (marked "dt"). This 100-question bank is an English MCQ study adaptation only—it does not simulate the official constructed-response format, selection strategy, or timed written production.

Time Limit

Abitur 2026 timetable lists Biologie and Biologie bilingual englisch in the same written window (09:00–14:00 on the published main/Nachtermin dates). Confirm exact working time and selection rules in the current Fächerlass and school instructions.

Passing Score

Subject performance is reported on the 15-point Notenpunkte scale after conversion from Bewertungseinheiten. Overall Abitur award depends on the Gesamtqualifikation (up to 900 points; typically 600 from Kursleistungen and 300 from the Abiturprüfung) under AGVO/Leitfaden rules—not a single MCQ percent cut score.

Exam / Certification Fees

Regular school candidates do not pay a separate published statewide Biologie bilingual subject fee; the exam is taken through the Gymnasium pathway. Any external-candidate fees are local/authority-specific and not invented here.
