Here is a flashcard for every question, complete and organized: Cellular Organelles Front: What is the function of the mitochondria in a cell? Back: Energy production Front: Which organelle is responsible for photosynthesis in plant cells? Back: Chloroplast Front: What does it mean when the plasma membrane is described as "selectively permeable"? Back: It only allows certain substances to pass through. Front: What is the main function of ribosomes? Back: Protein synthesis Front: Which organelle packages and distributes proteins? Back: Golgi apparatus Front: What structure in plant cells provides support and protection? Back: Cell wall Macromolecules Front: What are the building blocks of proteins? Back: Amino acids Front: Which macromolecule is primarily used as a source of energy? Back: Carbohydrates Front: What is the primary function of lipids? Back: Long-term energy storage and insulation Front: What are the building blocks of nucleic acids? Back: Nucleotides Cell Division Front: What is the purpose of mitosis? Back: To produce identical daughter cells Front: How many chromosomes are in a human gamete? Back: 23 Front: What process results in four genetically unique cells? Back: Meiosis Front: During which phase of mitosis do chromosomes line up in the middle of the cell? Back: Metaphase Front: What is the result of cytokinesis? Back: The cytoplasm is divided, resulting in two separate cells. Ecosystems Front: Which of the following is an abiotic factor: plants, animals, temperature, or microorganisms? Back: Temperature Front: What term describes the role an organism plays in its ecosystem? Back: Niche Front: What is the difference between an autotroph and a heterotroph? Back: Autotrophs make their own food; heterotrophs consume other organisms. Front: What is the primary source of energy for most ecosystems? Back: The Sun Front: What term describes a group of organisms of the same species living in a specific area? Back: Population Biology Basics Front: What is the definition of homeostasis? Back: Maintaining a stable internal environment Front: What molecule carries genetic information? Back: DNA (Deoxyribonucleic Acid) Front: What is the smallest unit of life? Back: The cell Front: What is the scientific method? Back: A process used to systematically study and solve problems. Human Systems Front: What is the primary purpose of the circulatory system? Back: To transport nutrients, oxygen, and waste Front: What is the main function of the nervous system? Back: To transmit signals and respond to stimuli Front: What organ filters waste from the blood? Back: The kidneys Front: What system is responsible for gas exchange in the body? Back: The respiratory system Chemistry of Life Front: What is the pH range for an acidic solution? Back: Less than 7 Front: What is the pH range for a basic solution? Back: Greater than 7 Front: What is the universal solvent? Back: Water Front: What is the primary element found in all organic molecules? Back: Carbon Food Chains and Ecosystems Front: What are producers in a food chain? Back: Organisms that produce their own food (usually through photosynthesis) Front: What are consumers in a food chain? Back: Organisms that eat other organisms for energy Front: What is the role of decomposers in an ecosystem? Back: To break down dead organisms and recycle nutrients Front: What is a trophic level? Back: A step in a food chain or web Photosynthesis Front: What process do plants use to convert sunlight into chemical energy?
