About this resource

This quiz covers the fundamental biological processes of photosynthesis and cellular respiration, making it appropriate for middle school science students at the 7th to 8th grade level. The questions assess students' understanding of the reactants and products of both processes, the cellular locations where these reactions occur (chloroplasts for photosynthesis and mitochondria for cellular respiration), and the chemical equations that represent these vital life processes. Students need to grasp that photosynthesis converts carbon dioxide and water into glucose and oxygen using sunlight energy captured by chlorophyll, while cellular respiration reverses this process by breaking down glucose with oxygen to release energy for cellular activities. The quiz also tests knowledge of aerobic respiration and the interconnected nature of these two processes in maintaining life on Earth through energy transformation and gas exchange. This quiz was created by a classroom teacher who designed it for students studying biology and life science in grades 7-8. The assessment serves multiple instructional purposes, functioning effectively as a formative assessment tool to gauge student comprehension before moving to more complex topics, or as review material to reinforce key concepts after direct instruction. Teachers can implement this quiz as a warm-up activity to activate prior knowledge, assign it as homework to encourage independent practice, or use it as a quick check for understanding during lessons on energy flow in living systems. The content directly supports Next Generation Science Standards MS-LS1-5 (constructing explanations for how plants use photosynthesis to transform matter and energy) and MS-LS1-7 (developing models to describe how food molecules are rearranged through chemical reactions to release energy for life processes).
