Question

The compensation point in plants is reached when...

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [Option B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Photosynthesis and respiration balance in plants
	**Related Topics**: Gas exchange, light intensity, plant physiology
	**Prerequisites**: Understanding of photosynthesis and respiration processes
## SOLUTION PATHWAY
**Given Information**:
		- Photosynthesis and respiration processes in plants
		- Compensation point definition
**Method & Steps**:
	1. Determine the definition of the compensation point.
		Reasoning: The compensation point is where the rates of photosynthesis and respiration are equal.
		Formula/Rule: 
		$$ \text{Rate of Photosynthesis} = \text{Rate of Respiration} $$
	2. Analyze the implications of reaching the compensation point.
		Working: At the compensation point, there is no net gas exchange, meaning the plant does not gain or lose carbon dioxide.
		Key Point: This balance allows the plant to maintain its energy needs without excess gas exchange.
	3. Confirm the conditions of the compensation point.
		Result: At this point, the plant is in a steady state with no net gain in energy.
		Verification: The chosen option must reflect this balance.
 ## OPTION ANALYSIS
[A] :x: Photosynthesis does not cease entirely; it continues at a rate equal to respiration.
[B] ✓: The rate of photosynthesis equals the rate of respiration, resulting in no net gas exchange.
[C] :x: Respiration does not cease; it continues alongside photosynthesis.
[D] :x: The switch to CAM photosynthesis is a different process and not relevant to the compensation point.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing respiration with photosynthesis: Remember, both processes occur simultaneously.
		2. Misunderstanding the term 'compensation': It refers to a balance, not a cessation of processes.
	**Quick Tips**:
		1. Visualize the balance of inputs (CO2, light) and outputs (O2) at the compensation point.
		2. Remember the role of light intensity; as light increases, photosynthesis increases until it reaches the compensation point.

Photosynthesis ceases entirely, and only respiration occurs.

D VINOD · Answer

The correct Option is "The rate of photosynthesis equals the rate of respiration, resulting in no net gas exchange."

D VINOD · Answer

Respiration ceases entirely, and only photosynthesis occurs.

D VINOD · Answer

The plant switches from C3 to CAM photosynthesis.
