Photosynthesis and Cellular Respiration Venn Diagram

Recall: Which cell types perform photosynthesis?

• Plant cells only

• Animal cells only

• Both plant and animal cells

• Neither plant nor animal cells

Recall: In which organelle does cellular respiration primarily occur?

• Chloroplast

• Mitochondria

• Nucleus

• Ribosome

Recall: What are the raw materials (inputs/reactants) of photosynthesis?

• Sugar and oxygen

• Carbon dioxide, water, and light energy

• Carbon dioxide and water only

• Sugar, water, and ATP

Recall: What are the products (outputs) of cellular respiration?

• Sugar and oxygen

• Carbon dioxide, water, and energy (ATP)

• Carbon dioxide and oxygen

• Water and light energy

Skill/Concept: Which statement best describes the relationship between photosynthesis and cellular respiration according to the diagram?

• They are unrelated processes that use different molecules.

• The products of photosynthesis are the inputs of cellular respiration and vice versa.

• Both processes produce the same products at the same time.

• Photosynthesis depends on mitochondria while respiration depends on chloroplasts.

Skill/Concept: Which equation fragment correctly matches its process?

• Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP): Photosynthesis

• Carbon Dioxide + Water + Light Energy → Sugar (glucose) + Oxygen: Photosynthesis

• Sugar (glucose) + Oxygen → Carbon Dioxide + Water: Photosynthesis

• Carbon Dioxide + Oxygen → Sugar + Water + ATP: Cellular respiration

Skill/Concept: Which pair correctly matches each process to its cell type occurrence?

• Photosynthesis in animal cells; respiration in plant cells only

• Photosynthesis in plant and animal cells; respiration in plant cells only

• Photosynthesis in plant cells only; respiration in plant and animal cells

• Both processes occur only in plant cells

Skill/Concept: Which set lists the correct organelle for each process?

• Photosynthesis—chloroplast; Cellular respiration—mitochondria

• Photosynthesis—mitochondria; Cellular respiration—chloroplast

• Photosynthesis—nucleus; Cellular respiration—ribosome

• Photosynthesis—vacuole; Cellular respiration—cell membrane

Strategic Thinking: A plant is placed in the dark for 48 hours but kept watered. Based on the diagram, which statement predicts what happens to its energy and gas use during that time?

• Photosynthesis increases and oxygen production rises because light is not needed.

• Photosynthesis decreases while cellular respiration continues using stored glucose and oxygen.

• Both photosynthesis and cellular respiration stop because plants only use light energy.

• Cellular respiration produces glucose to replace the lack of photosynthesis.

Strategic Thinking: If a closed terrarium has both plants and small insects, which exchange keeps both alive according to the Venn diagram?

• Plants and insects both release oxygen that the other uses for photosynthesis.

• Plants take in carbon dioxide and water to make glucose and oxygen; insects use glucose and oxygen to produce carbon dioxide, water, and ATP.

• Insects perform photosynthesis to supply glucose to plants that respire.

• Both rely only on ATP from sunlight without exchanging gases.
