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 have a simpler structure. Eukaryotic cells have a nucleus, membrane-bound organelles, and are typically larger and more complex.
What is the role of ATP in cellular processes?	ATP (adenosine triphosphate) acts as the primary energy currency of the cell, providing energy for various processes like muscle contraction, active transport, and biosynthesis.
How does photosynthesis convert light energy into chemical energy?	Photosynthesis captures light energy using chlorophyll in the chloroplasts, converting it into chemical energy stored in glucose molecules through the processes of light-dependent reactions and the Calvin cycle.
What are the stages of mitosis and their significance?	The stages of mitosis are prophase, metaphase, anaphase, and telophase. They ensure accurate division of the cell’s chromosomes into two identical daughter cells, vital for growth and tissue repair.
How are DNA and RNA different in structure and function?	DNA is double-stranded, contains deoxyribose, and stores genetic information. RNA is single-stranded, contains ribose, and plays roles in protein synthesis, such as mRNA, tRNA, and rRNA.
What is natural selection and how does it drive evolution?	Natural selection is the process where organisms with favorable traits are more likely to survive and reproduce, leading to the gradual evolution of populations over generations.
What are the key components of a scientific experiment in biology?	Key components include a hypothesis, independent and dependent variables, control and experimental groups, and procedures for data collection and analysis.
How do enzymes facilitate biological reactions?	Enzymes act as biological catalysts, lowering the activation energy required for reactions, thereby increasing reaction speed without being consumed in the process.
What is the significance of the cell cycle in growth and development?	The cell cycle, including phases like interphase and mitosis, regulates cell division, allowing organisms to grow, develop, and maintain tissues efficiently.
How do mutations affect genetic information and evolution?	Mutations are changes in DNA sequences that can lead to variations in traits. They are a source of genetic diversity and can drive evolution by introducing new traits that may be advantageous, neutral, or harmful.
