Question

Which of the following is NOT a function of a leaf?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Functions of leaves in plants
	**Related Topics**: Photosynthesis, transpiration, gas exchange, plant anatomy
	**Prerequisites**: Basic knowledge of plant biology and functions of different plant organs
## SOLUTION PATHWAY
**Given Information**:
		- Option A: Photosynthesis (a key function of leaves)
		- Option B: Transpiration (the process of water vapor loss)
		- Option C: Gas exchange (involves the intake of CO2 and release of O2)
		- Option D: Absorption of water from soil (not a function of leaves)
**Method & Steps**:
	1.	Identify the functions of leaves.
		Reasoning: Leaves are primarily involved in processes that support photosynthesis and gas exchange.
		Formula/Rule: None applicable here.
	2.	Analyze each option to determine its validity as a leaf function.
		Working: 
		- Photosynthesis (A) is a primary function of leaves, where they convert light energy into chemical energy.
		- Transpiration (B) helps in the movement of water and nutrients.
		- Gas exchange (C) occurs through stomata on leaves.
		- Absorption of water from soil (D) is done by roots, not leaves.
	3.	Conclude which option does not represent a leaf function.
		Result: D is the correct answer as leaves do not absorb water from the soil.
		Verification: Roots are responsible for water absorption, confirming D is not a function of leaves.
 ## OPTION ANALYSIS
[A] ✓: Photosynthesis is indeed a primary function of leaves, converting light energy into glucose.
[B] :x: Transpiration is a function that helps in water regulation and nutrient uptake in plants.
[C] :x: Gas exchange is a critical function of leaves, allowing for the exchange of gases with the atmosphere.
[D] :x: Absorption of water from soil is a function of roots, making this option the correct answer for the question asked.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the functions of roots and leaves: Always remember that leaves are for photosynthesis and gas exchange, while roots absorb water.
		2. Misunderstanding transpiration: It is often thought to be a root function, but it primarily occurs through leaves.
	**Quick Tips**:
		1. To remember leaf functions, think of the acronym 'P-G-T' for Photosynthesis, Gas exchange, and Transpiration.
		2. Visualize a plant: Roots are underground (water absorption), leaves are above ground (photosynthesis and gas exchange).
