Unlocking the Secrets of Photosynthesis with Amoeba Sisters
Photosynthesis is the vital process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. This complex process is crucial for life on Earth, and understanding its intricacies can be a fascinating journey. The Amoeba Sisters have created an engaging Photosynthesis Worksheet to help students delve into this subject, and we’re here to provide the answer key to assist with your learning.
Understanding Photosynthesis
Before diving into the worksheet, let’s briefly recap the key components of photosynthesis:
- Light-dependent reactions: These reactions occur in the thylakoid membranes of the chloroplast and involve the conversion of light energy into ATP and NADPH.
- Light-independent reactions (Calvin cycle): This cycle takes place in the stroma of the chloroplast and uses the ATP and NADPH produced in the light-dependent reactions to convert CO2 into glucose.

Section 2: Short Answer
- What is the difference between light-dependent and light-independent reactions? Answer: Light-dependent reactions occur in the thylakoid membranes and convert light energy into ATP and NADPH, while light-independent reactions (Calvin cycle) occur in the stroma and use ATP and NADPH to convert CO2 into glucose.
- Describe the role of chlorophyll in photosynthesis. Answer: Chlorophyll is the green pigment that absorbs light energy and plays a crucial role in the light-dependent reactions.
Section 3: Fill-in-the-Blank
- The energy from light is used to convert _______________________ into ATP and NADPH. Answer: ADP and NADP+
- The Calvin cycle uses _______________________ to convert CO2 into glucose. Answer: ATP and NADPH
Section 4: Essay Question
Describe the overall equation for photosynthesis and explain the importance of this process for life on Earth.
Answer: The overall equation for photosynthesis is:
6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2
Photosynthesis is crucial for life on Earth as it provides the energy and organic compounds necessary for the food chain. Without photosynthesis, plants would not be able to produce the glucose needed for growth and development, and ultimately, animals would not have the energy required to sustain life.
