Question

Which of the following statement is correct?
I. Many organs of aquatic plants floats in water
II. Large air gaps are present in the collenchyma tissue of lotus leaf

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Adaptations of aquatic plants and plant tissue structure.
	**Related Topics**: Buoyancy, aerenchyma, collenchyma, plant anatomy.
	**Prerequisites**: Basic understanding of plant anatomy and adaptations.
## SOLUTION PATHWAY
**Given Information**:
	Statement I: Many organs of aquatic plants float in water.
	Statement II: Large air gaps are present in the collenchyma tissue of lotus leaf.
	Correct answer is option A.
**Method & Steps**:
	1. Analyze Statement I: Many aquatic plants have adaptations to help them float. This includes air-filled spaces in their tissues, which increase buoyancy. Thus, statement I is correct.
		Reasoning: Aquatic plants need to float to access sunlight for photosynthesis.
		Formula/Rule: Buoyancy is related to the density of the object and the density of the fluid it is in.
	2. Analyze Statement II: Collenchyma is a plant tissue that provides structural support and is characterized by thickened cell walls. Collenchyma does not typically have large air gaps. Air gaps are found in aerenchyma tissue. Lotus leaves have aerenchyma, not collenchyma, with large air gaps.
		Working: Collenchyma is for support, while aerenchyma is for buoyancy.
		Key Point: Air gaps are found in aerenchyma, not collenchyma.
	3. Conclusion: Statement I is correct, and Statement II is incorrect.
		Result: Option A is the correct answer.
		Verification: The correct answer aligns with known facts about plant adaptations.
 ## OPTION ANALYSIS
[A] ✓: Statement I is correct, and Statement II is incorrect as aerenchyma tissue has large air gaps not collenchyma.
[B] :x: Statement I is correct not incorrect.
[C] :x: Statement II is incorrect.
[D] :x: Statement I is correct.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing collenchyma and aerenchyma tissues. [How to avoid]: Remember that collenchyma is for support and aerenchyma is for buoyancy.
		2.[Error 2]: Assuming all plant tissues have air gaps. [How to avoid]: Understand that different tissues have different functions.
	**Quick Tips**:
		1.[Helpful shortcut]: Aerenchyma has 'air' in the name, helping you remember it's for air spaces.
		2.[Memory aid]: Collenchyma=support, Aerenchyma=air.
