Key Concepts: Comparison Of Photosynthesis And Cellular Respiration Worksheet
Definition of Photosynthesis and Cellular Respiration
Photosynthesis is the process by which plants and certain other organisms convert light energy into chemical energy, storing it in the form of glucose molecules. In contrast, cellular respiration is the process by which cells use oxygen to break down glucose molecules, releasing energy in the form of ATP.
Similarities and Differences
Photosynthesis and cellular respiration are both essential for life, as they provide the energy needed for cells to function. However, there are key differences between the two processes:
- Photosynthesis requires light energy, while cellular respiration does not.
- Photosynthesis produces glucose, while cellular respiration breaks down glucose.
- Photosynthesis occurs in chloroplasts, while cellular respiration occurs in mitochondria.
Comparing the Processes
| Photosynthesis | Cellular Respiration | |
|---|---|---|
| Reactants | Carbon dioxide, water, light energy | Glucose, oxygen |
| Products | Glucose, oxygen | Carbon dioxide, water, ATP |
| Location | Chloroplasts | Mitochondria |
| Energy Requirements | Light energy | No light energy required |
Examples and Applications
Photosynthesis, Comparison of photosynthesis and cellular respiration worksheet
Photosynthesis is essential for the growth and survival of plants, providing them with the energy they need to grow and reproduce. It also plays a vital role in the global carbon cycle, absorbing carbon dioxide from the atmosphere and releasing oxygen.
Cellular Respiration
Cellular respiration is essential for all living organisms, providing them with the energy they need to perform cellular activities such as muscle contraction, nerve impulse transmission, and protein synthesis. It also plays a role in the recycling of carbon and nitrogen.

Key Questions Answered
What is the primary difference between photosynthesis and cellular respiration?
Photosynthesis utilizes light energy to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct, while cellular respiration harnesses the energy stored in glucose to produce ATP, releasing carbon dioxide and water as byproducts.
Where do these processes occur within plant cells?
Photosynthesis takes place in the chloroplasts, while cellular respiration occurs in the mitochondria.
How do these processes contribute to the cycling of matter and energy in ecosystems?
Photosynthesis fixes carbon dioxide into organic molecules, making it available to other organisms, while cellular respiration releases carbon dioxide back into the atmosphere, completing the carbon cycle. Both processes contribute to the flow of energy through food chains.
