Food Factory

This passage explains how plants create their own food through photosynthesis, a process that occurs in chloroplasts. It details the two stages: the light-dependent reactions, which convert sunlight into chemical energy, and the Calvin cycle, which uses that energy to produce sugars from carbon dioxide. Chlorophyll is again emphasized as the critical component in capturing sunlight. The passage concludes by highlighting how plants generate energy and why this process is essential for life on Earth.

This passage introduces students to both scientific vocabulary and conceptual understanding, such as how energy production occurs in plants. It helps develop comprehension skills by requiring students to follow multi-step processes like the light-dependent reactions and Calvin cycle. Reading such passages promotes critical thinking as students consider the importance of photosynthesis to all life forms. Exposure to the use of technical language in different contexts also improves writing fluency and grammar awareness.
