Which of the given genera is homosporous ?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
**Primary Concept**: Homospory and Heterospory in plants
**Related Topics**: Plant Classification, Life cycles of plants, Spore types
**Prerequisites**: Basic knowledge of plant classification and reproductive strategies
## SOLUTION PATHWAY
**Given Information**:
    List of plant genera: Cycas, Pinus, Selaginella, Lycopodium
    The question asks to identify the homosporous genus.
**Method & Steps**:
    1. **Recall Definition:** Homosporous plants produce only one type of spore that develops into a bisexual gametophyte.
    2. **Recall Plant Groups:**
        - Cycas and Pinus are gymnosperms, which are heterosporous.
        - Selaginella is a pteridophyte (fern ally) that is heterosporous.
        - Lycopodium is a pteridophyte (fern ally) that is homosporous.
    3. **Identify the answer:** Based on this recall, Lycopodium is the homosporous genus.
## OPTION ANALYSIS
[A] :x: Cycas is a gymnosperm and heterosporous.
[B] :x: Pinus is a gymnosperm and heterosporous.
[C] :x: Selaginella is a pteridophyte but heterosporous.
[D] ✓: Lycopodium is a pteridophyte and homosporous.
## LEARNING AIDS
**Common Mistakes**:
    1. Confusing homospory and heterospory: Understand that homospory means one type of spore, and heterospory means two types of spores.
    2. Incorrectly classifying plant groups: Memorizing the major plant groups (bryophytes, pteridophytes, gymnosperms, angiosperms) and their reproductive strategies helps.
**Quick Tips**:
    1. Use mnemonics to memorize the homosporous pteridophytes (e.g., 'L' for Lycopodium).
    2. Remember that gymnosperms and angiosperms are always heterosporous.
