Question

Which of these is required for photosynthesis?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
 **Primary Concept**: Photosynthesis
 **Related Topics**: Chloroplasts, light-dependent reactions, light-independent reactions, cellular respiration
 **Prerequisites**: Basic understanding of plant biology and cellular processes.
## SOLUTION PATHWAY
**Given Information**:
  The question asks which component is necessary for photosynthesis.
  Options: Chlorophyll, Mitochondria, Oxygen, Glucose
**Method & Steps**:
 1. Understand the process of photosynthesis.
  Reasoning: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
  Formula/Rule:  $6CO_2 + 6H_2O \xrightarrow{Sunlight, Chlorophyll} C_6H_{12}O_6 + 6O_2$
 2. Analyze each option's role in photosynthesis.
  Working: 
            * Chlorophyll:  Essential pigment that absorbs light energy.
            * Mitochondria: Involved in cellular respiration, not directly in photosynthesis.
            * Oxygen: A product of photosynthesis, not a reactant.
            * Glucose: A product of photosynthesis, not a reactant.
 3. Identify the essential component.
  Result: Chlorophyll is the only option directly required for photosynthesis.
  Verification: The balanced equation for photosynthesis clearly shows that chlorophyll is needed as a catalyst for the reaction.
 ## OPTION ANALYSIS
A ✓: Chlorophyll is the primary pigment used in photosynthesis to capture light energy. Without chlorophyll, plants cannot perform photosynthesis.
B :x: Mitochondria are the powerhouses of the cell and are involved in cellular respiration, the process of breaking down glucose to produce ATP. They are not directly involved in photosynthesis.
C :x: Oxygen is a byproduct of photosynthesis, released as a waste product after water is split.
D :x: Glucose is the sugar produced during photosynthesis; it is the end product, not a requirement.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing photosynthesis with cellular respiration: Remember that photosynthesis produces glucose and oxygen, while cellular respiration uses glucose and oxygen.
  2.Thinking oxygen is required for photosynthesis: Oxygen is a product, not a reactant, of photosynthesis.
 **Quick Tips**:
  1.Remember the equation for photosynthesis: $6CO_2 + 6H_2O \xrightarrow{Sunlight, Chlorophyll} C_6H_{12}O_6 + 6O_2$
  2.Chlorophyll is green because it reflects green light and absorbs other wavelengths of light needed for photosynthesis.
