Question

Light compensation point is the point where

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Photosynthesis and Respiration
	**Related Topics**: Plant Physiology, Gas Exchange, Light Intensity
	**Prerequisites**: Understanding of photosynthesis and respiration processes.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the light compensation point.
**Method & Steps**:
	1. **Define Light Compensation Point**: The light compensation point is the light intensity at which the rate of photosynthesis exactly matches the rate of respiration.
		Reasoning: At this point, the net carbon dioxide uptake is zero.
	2. **Relate to Options**:  The option that describes this balance is 'The rate of photosynthesis equals the rate of respiration'.
		Working:  Photosynthesis produces glucose and oxygen, while respiration consumes glucose and oxygen. At the light compensation point, these processes are balanced.
		Key Point: Below the light compensation point, the rate of respiration exceeds the rate of photosynthesis, and the plant consumes stored carbohydrates. Above the light compensation point, the rate of photosynthesis exceeds the rate of respiration, and the plant produces excess carbohydrates.
	3. **Select Correct Option**: Option B accurately describes the light compensation point.
		Result: B
		Verification: The definition of the light compensation point aligns with option B.
## OPTION ANALYSIS
[A] :x: There is no photosynthesis:  Photosynthesis still occurs at the light compensation point, but its rate is balanced by respiration.
[B] ✓: The rate of photosynthesis equals the rate of respiration: This is the correct definition of the light compensation point.
[C] :x: There is no respiration: Respiration occurs continuously in plants.
[D] :x: The rate of photosynthesis is maximum: The maximum rate of photosynthesis occurs at the light saturation point, which is at a higher light intensity than the light compensation point.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing light compensation point with light saturation point: Remember that the compensation point is about balance, while the saturation point is about maximum rate.
		2. Thinking photosynthesis stops at the compensation point: Photosynthesis continues, but the net CO2 exchange is zero.
	**Quick Tips**:
		1. Compensation = Balance
		2. Saturation = Maximum
