Question	Answer
What are the main differences between prokaryotic and eukaryotic cells?	Prokaryotic cells lack a nucleus and membrane-bound organelles, are generally smaller, and include bacteria and archaea. Eukaryotic cells have a defined nucleus, membrane-bound organelles, and include plants, animals, fungi, and protists.
How does photosynthesis benefit both plants and humans?	Photosynthesis allows plants to produce glucose and oxygen from sunlight, carbon dioxide, and water. Humans benefit because it provides the oxygen we breathe and the basis for food sources in the food chain.
What is the role of enzymes in biological reactions?	Enzymes act as biological catalysts, speeding up chemical reactions by lowering activation energy, which allows reactions to occur more efficiently at body temperature.
Describe the process of cellular respiration.	Cellular respiration is the process by which cells convert glucose and oxygen into energy in the form of ATP, releasing carbon dioxide and water as byproducts. It includes glycolysis, the Krebs cycle, and the electron transport chain.
What is the significance of the scientific method in biology?	The scientific method provides a systematic way to investigate biological phenomena through observation, hypothesis formation, experimentation, and analysis, ensuring reliable and reproducible results.
How do genetic traits are inherited according to Mendel's laws?	Mendel's laws state that traits are inherited through discrete units called genes, with the Law of Segregation indicating alleles separate during gamete formation, and the Law of Independent Assortment stating genes for different traits are inherited independently.
