Question

Which of these features is NOT characteristic of Sphagnum?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Characteristics of Sphagnum moss
 **Related Topics**: Bryophytes, peat formation, plant morphology
 **Prerequisites**: Basic knowledge of plant anatomy and ecology.
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify a feature NOT found in Sphagnum moss.
  Options: Hygroscopic nature, Presence of elaters, Formation of peat, Absence of rhizoids
**Method & Steps**:
 1. Analyze each option to determine if it's a characteristic of Sphagnum.
  Reasoning: Sphagnum is a genus of moss known for its specific properties.
 2. Identify the option that is NOT a characteristic.
  Working: Let's examine each option:
  a) Hygroscopic nature: Sphagnum is highly hygroscopic, meaning it can absorb and retain large amounts of water.
  b) Presence of elaters:  Elaters are hygroscopic structures found in the sporangia of some liverworts and horsetails, assisting in spore dispersal. They are NOT present in Sphagnum.
  c) Formation of peat: Sphagnum is a major component of peat bogs, forming peat through incomplete decomposition.
  d) Absence of rhizoids: Sphagnum has poorly developed rhizoids (root-like structures) compared to other mosses.
 3. Conclude which option is not a characteristic of Sphagnum.
  Result: The presence of elaters is not a characteristic of Sphagnum.
  Verification:  Referencing botanical texts confirms the absence of elaters in Sphagnum.
 ## OPTION ANALYSIS
A ✓: Hygroscopic nature is a key characteristic of Sphagnum, enabling it to hold significant amounts of water.
B :x: Elaters are not found in Sphagnum. They are associated with other plant groups for spore dispersal.
C :x: Sphagnum is the primary contributor to peat formation in peat bogs.
D :x: Sphagnum has reduced rhizoids, which is a distinctive feature.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing Sphagnum with other bryophytes: Understanding the unique features of Sphagnum is crucial.
  2.Misinterpreting the question:  Focus on identifying the feature that is NOT present.
 **Quick Tips**:
  1.Remember the key features of Sphagnum: hygroscopic nature, peat formation, reduced rhizoids.
  2.Use mnemonics or diagrams to remember the characteristics of different plant groups.
