Photosynthesis & cellular respiration worksheet answers – Delving into the realm of photosynthesis & cellular respiration, this comprehensive worksheet unveils the intricate processes that sustain life on Earth. Embark on a journey of discovery as we explore the fundamental definitions, contrasting characteristics, and pivotal roles of these biological powerhouses.
Photosynthesis, the lifeblood of our planet, harnesses sunlight to transform carbon dioxide and water into the very essence of life: glucose. Cellular respiration, on the other hand, harnesses the energy stored in glucose to fuel cellular activities and growth.
Photosynthesis and Cellular Respiration: Definitions and Processes: Photosynthesis & Cellular Respiration Worksheet Answers
Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy, stored in the form of glucose. It involves the use of sunlight, carbon dioxide, and water to produce glucose and oxygen. The overall equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
Cellular respiration is the process by which cells use oxygen to break down glucose and other organic molecules, releasing energy in the form of ATP. The overall equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (as ATP).
Key Differences between Photosynthesis and Cellular Respiration
| Photosynthesis | Cellular Respiration | |
|---|---|---|
| Reactants | Carbon dioxide, water, light energy | Glucose, oxygen |
| Products | Glucose, oxygen | Carbon dioxide, water, ATP |
| Location | Chloroplasts in plant cells | Mitochondria in all cells |
| Energy transformation | Light energy → chemical energy | Chemical energy → ATP |
Importance of Photosynthesis and Cellular Respiration
Photosynthesis is essential for life on Earth as it provides the oxygen we breathe and the food we eat. It is the basis of the food chain, as plants are the primary producers that convert sunlight into energy that can be used by other organisms.
Cellular respiration is equally important as it provides the energy that cells need to function. This energy is used for a variety of cellular activities, including growth, movement, and reproduction.
Factors Affecting Photosynthesis and Cellular Respiration, Photosynthesis & cellular respiration worksheet answers
The rate of photosynthesis is affected by a number of factors, including light intensity, temperature, and carbon dioxide concentration. The rate of cellular respiration is affected by factors such as temperature, oxygen availability, and substrate concentration.
Applications of Photosynthesis and Cellular Respiration
Photosynthesis is used in agriculture to increase crop yields. It is also used in biotechnology to produce biofuels and other renewable energy sources.
Cellular respiration is used in industrial applications such as biofuel production and wastewater treatment. It is also used in the production of antibiotics and other pharmaceuticals.
