Question

Which statement is incorrect about Pinus?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Gymnosperm characteristics
	**Related Topics**: Plant anatomy, Plant physiology, Plant taxonomy
	**Prerequisites**: Basic knowledge of plant structure and gymnosperm characteristics.
## SOLUTION PATHWAY
**Given Information**:
	Characteristics of Pinus are being evaluated.
**Method & Steps**:
	1. Analyze each option for its relevance to Pinus characteristics.
	Reasoning: Pinus belongs to the Gymnosperms.
	2. Identify the incorrect statement based on known features of Gymnosperms and specifically Pinus.
	Key Point: Gymnosperms are characterized by the absence of vessels in xylem, except for Gnetales.
	3. Select the option that contradicts established facts about Pinus.
	Result: Presence of vessels in xylem is incorrect.
	Verification: Pinus, being a gymnosperm (excluding Gnetales), lacks vessels in its xylem.
## OPTION ANALYSIS
[A] ✓: Mycorrhizal roots: Pinus forms symbiotic relationships with fungi, resulting in mycorrhizal roots. This association helps in nutrient absorption.
[B] ✓: Winged pollen grains: Pinus has winged pollen grains, an adaptation for wind pollination.
[C] ✓: Needle-like leaves: Pinus possesses needle-like leaves, which reduce water loss and provide adaptation to harsh environments.
[D] :x: Presence of vessels in xylem: Pinus, like most gymnosperms, lacks vessels in its xylem. Xylem transport occurs through tracheids. This is the incorrect statement.
## LEARNING AIDS
	**Common Mistakes**:
		1. Generalizing angiosperm characteristics to gymnosperms:  Remember that gymnosperms and angiosperms have distinct features, particularly in their vascular tissues.
		2. Ignoring exceptions within groups: While most gymnosperms lack vessels, exceptions like Gnetales exist. Be mindful of these exceptions.
	**Quick Tips**:
		1. Remember 'P' in Pinus and 'P' in Pits (characteristic of tracheids) to associate Pinus with the absence of vessels.
		2. Visualize the needle-like leaves and winged pollen grains of Pinus to recall its key characteristics.
