Photosynthesis & Cellular Respiration Worksheet
1. What are the organisms that make their own food?
A. Chloroplasts
B. Autotroph (producer)
Answer:
The organisms that make their own food are Autotrophs (producers).
Autotrophs, also known as producers, are organisms that have the ability to make their own food through processes like photosynthesis. They convert sunlight into energy, which is then used to produce glucose as their food source.
2. Where does photosynthesis take place?
A. Chloroplasts
Answer:
Photosynthesis takes place in the chloroplasts.
Chloroplasts are the organelles in plant cells where photosynthesis occurs. These structures contain chlorophyll, a pigment that captures sunlight and initiates the process of converting light energy into chemical energy.
3. What is the energy storing molecule in cells?
A. ATP
Answer:
The energy storing molecule in cells is ATP.
ATP (adenosine triphosphate) is the main energy currency of the cell. It stores and carries energy within cells for various cellular processes, including muscle contractions, protein synthesis, and active transport.
4. What is the final product of photosynthesis?
A. Glucose (C6H12O6)
Answer:
The final product of photosynthesis is Glucose (C6H12O6).
Glucose is a sugar molecule that serves as the main source of energy for living organisms. It is produced during photosynthesis as a result of converting solar energy into chemical energy in plants.
5. Compare & contrast the equations for photosynthesis and aerobic respiration.
Answer:
Photosynthesis and aerobic respiration are important processes that involve the conversion of energy. Photosynthesis converts solar energy into chemical energy in the form of glucose, while aerobic respiration breaks down glucose to release energy in the form of ATP. The two processes have opposite equations.
Photosynthesis: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Aerobic Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
Photosynthesis and aerobic respiration are both essential cellular processes that involve the conversion of energy. While photosynthesis converts solar energy into chemical energy (glucose), aerobic respiration utilizes glucose to produce ATP, the main energy currency of the cell. These processes complement each other in the energy production and utilization cycle of living organisms.
