Question	Answer
What are the main differences between plant and animal cells?	Plant cells have cell walls, chloroplasts, and a large central vacuole, whereas animal cells lack cell walls and chloroplasts and have smaller vacuoles. These differences reflect their distinct functions in photosynthesis and movement.
How does the process of photosynthesis work?	Photosynthesis is the process by which green plants convert sunlight, carbon dioxide, and water into glucose and oxygen. It occurs in the chloroplasts and involves the light-dependent and light-independent (Calvin cycle) reactions.
What is the role of DNA in living organisms?	DNA carries genetic information that determines an organism's traits and guides cell functions. It is the blueprint for building proteins and is passed from parents to offspring during reproduction.
How do enzymes facilitate biological reactions?	Enzymes are proteins that speed up chemical reactions by lowering activation energy, making reactions occur faster and more efficiently in the body.
What is natural selection and how does it lead to evolution?	Natural selection is the process where organisms with advantageous traits are more likely to survive and reproduce. Over time, this leads to changes in the species' traits, driving evolution.
Why is biodiversity important for ecosystems?	Biodiversity contributes to ecosystem stability, productivity, and resilience. It ensures the availability of resources and helps ecosystems recover from disturbances.
What are the key functions of the human circulatory system?	The circulatory system transports oxygen, nutrients, hormones, and waste products throughout the body, and helps regulate temperature and maintain homeostasis.
How do viruses differ from bacteria?	Viruses are non-living particles that require a host to reproduce, while bacteria are single-celled living organisms capable of independent growth and reproduction.
What is the significance of the cell cycle in growth and development?	The cell cycle is a series of stages that cells go through to grow and divide. It is essential for tissue growth, repair, and reproduction of organisms.
