Step-by-step solution for: Photosynthesis vs. Cellular Respiration Comparison Interactive ...
Here's a detailed solution to the 10 questions based on the provided diagram comparing Photosynthesis and Cellular Respiration:
---
Answer:
Photosynthesis occurs in plants, protists (e.g., algae), and bacteria (specifically cyanobacteria and some other photosynthetic bacteria).
> *Explanation:* The diagram under “PHOTOSYNTHESIS → ORGANISMS” shows icons for plants, protists (labeled “Protists (Algae)”), and bacteria — indicating these are the organisms capable of photosynthesis.
---
Answer:
Photosynthesis does not occur in animals, fungi, and most bacteria (non-photosynthetic ones).
> *Explanation:* While the diagram doesn’t explicitly list “non-photosynthetic organisms,” we know from biology that animals and fungi lack chloroplasts and cannot perform photosynthesis. The diagram’s “Cellular Respiration” side includes animals and fungi, implying they rely on respiration, not photosynthesis.
---
Answer:
The reactants of photosynthesis are:
→ Sunlight (energy)
→ Carbon dioxide (CO₂)
→ Water (H₂O)
> *Explanation:* The diagram under “REAGENTS + PRODUCTS” for photosynthesis shows sun, CO₂, and H₂O as inputs (reactants) leading to products.
---
Answer:
The products of photosynthesis are:
→ Glucose (C₆H₁₂O₆) — shown as a green hexagon
→ Oxygen (O₂) — shown as blue O₂ molecule
> *Explanation:* The arrow points from reactants to glucose and oxygen, indicating they are the outputs (products) of the process.
---
Answer:
The products of photosynthesis that are used as reactants in cellular respiration are:
→ Glucose (C₆H₁₂O₆)
→ Oxygen (O₂)
> *Explanation:* Cellular respiration uses glucose and oxygen to produce energy (ATP). The diagram for cellular respiration lists glucose and O₂ as its “REAGENTS.” These are exactly the products of photosynthesis — showing the cyclical relationship between the two processes.
---
Answer:
Cellular respiration occurs in animals, plants, protists (e.g., amoeba), fungi, and bacteria.
> *Explanation:* The diagram under “CELLULAR RESPIRATION → ORGANISMS” shows icons for all these groups — indicating that all living organisms carry out cellular respiration to produce ATP for energy.
---
Answer:
Cellular respiration does not occur in non-living things (like rocks, water, or machines).
*Technically, no known living organism avoids cellular respiration entirely — even anaerobic organisms perform some form of respiration (fermentation or anaerobic respiration).*
> *Note:* Since the question asks what organisms it does NOT occur in, the answer is: none — all living organisms perform some form of cellular respiration. If forced to pick from the diagram, there are no organisms listed that do NOT perform it — because even photosynthetic organisms respire too!
---
Answer:
The reactants of cellular respiration are:
→ Glucose (C₆H₁₂O₆)
→ Oxygen (O₂)
> *Explanation:* The diagram clearly labels glucose and O₂ as “REAGENTS” for cellular respiration.
---
Answer:
The products of cellular respiration are:
→ Carbon dioxide (CO₂)
→ Water (H₂O)
→ ATP (energy) — shown as lightning bolt/energy symbol
→ Heat — shown as flame icon
> *Explanation:* The diagram under “PRODUCTS” for cellular respiration lists CO₂, H₂O, ATP, and heat — which matches the chemical equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP + Heat
---
Answer:
The products of cellular respiration that are used as reactants in photosynthesis are:
→ Carbon dioxide (CO₂)
→ Water (H₂O)
> *Explanation:* Photosynthesis requires CO₂ and H₂O as inputs. These are produced by cellular respiration. This completes the biological cycle:
Photosynthesis makes food and O₂ → Respiration uses food and O₂ to make CO₂ and H₂O → Photosynthesis uses CO₂ and H₂O again.
