Chapter Summary
Understand the criteria used to differentiate between living and non-living things, including visible movements (growth, breathing) and the necessity of invisible molecular movements for maintenance and repair of organized structures.
Identify and understand the purpose of the four key life processes required to maintain life: nutrition (energy intake), respiration (energy release), transportation (distribution of substances), and excretion (waste removal).
Explain why simple diffusion is insufficient to meet the oxygen and nutrient requirements of all cells in complex multicellular organisms, which necessitates the development of specialized tissues and transport systems.
Differentiate between autotrophic and heterotrophic nutrition. Understand that autotrophs create their own food from simple inorganic sources, while heterotrophs obtain complex organic food from other organisms.
Define photosynthesis as the process by which autotrophs (like green plants) convert light energy into chemical energy, using carbon dioxide and water to produce carbohydrates for energy and storage (as starch).
Describe the three main events in photosynthesis: 1) absorption of light energy by chlorophyll, 2) conversion of light energy to chemical energy and splitting of water, and 3) reduction of carbon dioxide into carbohydrates. Be familiar with the overall chemical equation.
Identify chloroplasts as the specific cell organelles where photosynthesis occurs and recognize the essential roles of chlorophyll, carbon dioxide, water, and sunlight as the key components and raw materials for the process.
