Explanations: answer key for all 10 questions
- Q1: Which part of a cell releases energy from food?
Answer: The mitochondria
Mitochondria turn sugar and oxygen into usable energy. They have their own small set of DNA.
- Q2: What do plants make during photosynthesis?
Answer: Sugar and oxygen
Plants use sunlight, water and carbon dioxide to make sugar. Oxygen is released as a by-product.
- Q3: What shape is the DNA molecule?
Answer: A double helix
James Watson and Francis Crick described the structure in 1953, using X-ray images by Rosalind Franklin.
- Q4: Charles Darwin's ideas about evolution were inspired partly by finches on which islands?
Answer: The Galápagos Islands
Darwin visited the Galápagos in 1835 aboard HMS Beagle. He published On the Origin of Species in 1859.
- Q5: Gregor Mendel discovered the basic rules of heredity by studying which plant?
Answer: Pea plants
Mendel bred thousands of pea plants in a monastery garden. His work was largely ignored until 1900.
- Q6: What do white blood cells mainly do?
Answer: Fight infections
Red blood cells carry oxygen and platelets help clotting. White blood cells attack germs and remember them.
- Q7: In a food chain, what are plants called?
Answer: Producers
Plants produce their own food from sunlight. Animals that eat them are consumers, and fungi and bacteria are decomposers.
- Q8: Which of these do plant cells have but animal cells do not?
Answer: A cell wall and chloroplasts
The cell wall gives plants support and chloroplasts capture sunlight. Both cell types have a nucleus and mitochondria.
- Q9: About how many cells make up the human body?
Answer: About 30 trillion
Estimates are around 30 to 37 trillion human cells. Red blood cells make up the largest share.
- Q10: Who discovered penicillin in 1928 after noticing mold killing bacteria?
Answer: Alexander Fleming
Fleming noticed the mold in a dish he had left out. Penicillin became the first widely used antibiotic in the 1940s.
Bing Biology Quiz – Cells, Evolution and Living Systems
Biology is the study of life, from single cells to entire ecosystems. Living things solve problems in clever ways: they capture energy, defend themselves, reproduce and adapt to changing environments over many generations.
Cells are the building blocks. Mitochondria release energy from food, plant cells have walls and chloroplasts, and the human body contains around 30 trillion cells. DNA, shaped like a double helix, carries the instructions for building every living thing.
Big ideas changed biology. Gregor Mendel discovered the rules of heredity with pea plants, Charles Darwin explained evolution by natural selection after visiting the Galápagos Islands and Alexander Fleming's discovery of penicillin launched the age of antibiotics.
Living systems connect in food chains and ecosystems. Plants are producers that make sugar and oxygen through photosynthesis, animals are consumers and fungi and bacteria break down waste. Inside our bodies, white blood cells fight infections, and the immune system remembers germs it has met before so it can respond faster next time.
Ten questions, three options each and 150 seconds on the clock: that is the challenge of the Bing Biology Quiz. Read every question carefully, because some answers are designed to look right at first glance. The explanation after each answer shows the reasoning, and you can play again to improve your score. The score is just for fun, so there is no pressure. If a question surprises you, read the explanation and try a related quiz afterward to build on what you learned.
