Select the correct statement:

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
**Primary Concept**: Characteristics of Gymnosperms
**Related Topics**: Plant classification, plant morphology, plant adaptations
**Prerequisites**: Basic understanding of plant kingdom classification, knowledge of gymnosperm characteristics
## SOLUTION PATHWAY
**Given Information**:
    - Multiple statements about gymnosperms and related plants.
    - Need to identify the correct statement.
**Method & Steps**:
    1. Analyze Statement A: Gymnosperms are heterosporous, not both homosporous and heterosporous.
        Reasoning: Gymnosperms produce two types of spores (microspores and megaspores), making them heterosporous.
        Formula/Rule: Definition of heterosporous and homosporous plants.
    2. Analyze Statement B: Salvinia is a fern (pteridophyte), not a gymnosperm. Ginkgo and Pinus are gymnosperms.
        Reasoning: Salvinia is a free-floating aquatic fern, while ginkgo and pinus are seed-bearing plants that are classified as gymnosperms.
        Key Point: Plant classification is crucial to differentiate between different groups.
    3. Analyze Statement C: Sequoia is known to be one of the tallest trees.
        Reasoning: Sequoias are giant trees known for their massive size and height. 
        Key Point: General knowledge of plant species.
    4. Analyze Statement D: Gymnosperm leaves are often adapted to extremes of climate (e.g., needle-like leaves in conifers).
        Reasoning: Gymnosperms, especially conifers, have adaptations like thick cuticles and reduced surface area (needle-like leaves) to reduce water loss in dry or cold environments.
        Key Point: Gymnosperm adaptations to environmental conditions.
 ## OPTION ANALYSIS
[A] :x: Incorrect because Gymnosperms are heterosporous only.
[B] :x: Incorrect because Salvinia is a pteridophyte (fern) not a gymnosperm.
[C] ✓: Correct because Sequoias are known for their height.
[D] :x: Incorrect because Gymnosperm leaves are very well adapted to extremes of climate.
 ## LEARNING AIDS
**Common Mistakes**:
    1. Confusing homosporous and heterosporous: Remember that gymnosperms produce two types of spores and are thus heterosporous.
        2. Misclassifying plants: Be sure to review plant classification to avoid confusing different plant groups.
**Quick Tips**:
    1. Use memory aids like “hetero = different” to remember heterosporous plants.
    2. Remember specific examples of gymnosperms like pine trees and sequoias to aid in understanding their characteristics.
