Web9 jun. 2024 · When plants have enough sunlight, water, and fertile soil, the photosynthesis cycle continues to churn out more and more glucose. Glucose is like food that plants use to build their bodies. They combine thousands of glucose molecules to make cellulose, the main component of their cell walls. The more cellulose they make, the more they grow. WebD Photosynthesis is an exothermic reaction, so more energy is absorbed making bonds than is released breaking bonds. Q2: A student mixes 25 mL of hydrochloric acid with 25 mL of sodium hydroxide solution. She records the temperature at the start of the reaction and once again 30 seconds later.
