How it works
This photosynthesis and cellular respiration diagram quiz names a part and you tap it on the drawing: a diagram to label, not a bank of test questions.
Read the full guide
Which box is on which arrow
The arrow over the top runs from the chloroplast to the mitochondrion, so its box holds what photosynthesis makes: glucose and oxygen. The arrow underneath runs back, and its box holds what cellular respiration gives off: carbon dioxide and water. Each pair is one answer. Light energy is the box beside the sun, and ATP is the box with rays above the mitochondrion.
Organelle or process
The chloroplast is the oval with stacks inside and the mitochondrion is the oval with a folded membrane inside. The two processes are the blank boxes under them, so photosynthesis is asked at the box and never at the oval above it.
Questions and answers
Is ATP made in photosynthesis or in cellular respiration?
In both. The light-dependent reactions of photosynthesis make ATP, but the Calvin cycle uses it up building sugar. The ATP box on this drawing sits by the mitochondrion, because cellular respiration makes the ATP a cell can spend on other work.
Where does the energy in ATP come from?
From light. Photosynthesis stores light energy in glucose, and cellular respiration moves that energy into ATP. Energy comes into the drawing once, at the sun, while the molecules on the two arrows go round.
What are the stacks inside a chloroplast called?
Grana: stacks of thylakoids. This quiz asks the chloroplast as one part, so the stacks are not asked by name.
