Unlike other bryophytes, Anthoceros exhibits:

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Bryophyte characteristics and differences between Anthoceros and other bryophytes.
 **Related Topics**: Plant morphology, life cycle of bryophytes, chloroplast structure.
 **Prerequisites**: Basic understanding of bryophyte classification and their general characteristics.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the unique characteristic of Anthoceros compared to other bryophytes.
**Method & Steps**:
1. Analyze the options:
    a.  A dominant sporophyte generation: This is not unique to Anthoceros.  While the sporophyte is more developed in Anthoceros than in other bryophytes, it's not dominant.
    b. Absence of a pyrenoid: Pyrenoids are structures within chloroplasts involved in carbon fixation. Their presence or absence isn't a defining characteristic distinguishing Anthoceros from other bryophytes.
    c. A single large chloroplast per cell: This is a distinctive feature of Anthoceros.  Most other bryophytes have multiple smaller chloroplasts per cell.
    d. Dependent gametophyte:  The gametophyte is the dominant generation in all bryophytes, including Anthoceros.  The sporophyte is dependent on the gametophyte for nutrition.
2. Compare the options with known characteristics of Anthoceros:
    Anthoceros is known for its unique morphological features, including the presence of a single large chloroplast per cell in its cells.
3. Identify the unique characteristic:
    The single large chloroplast per cell is the characteristic that sets Anthoceros apart from other bryophytes.
  Result: Option C is the correct answer.
  Verification:  The unique chloroplast structure of Anthoceros is a well-established fact in botany.
 ## OPTION ANALYSIS
A :x:  The sporophyte in Anthoceros is larger and more independent than in other bryophytes, but it's still not the dominant generation.
B :x:  The presence or absence of pyrenoids is not a key distinguishing feature for Anthoceros.
C ✓: Anthoceros is characterized by having a single, large chloroplast per cell, unlike other bryophytes which typically have multiple, smaller chloroplasts.
D :x:  Like all bryophytes, Anthoceros has a dependent sporophyte generation; the gametophyte is dominant.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the dominance of the sporophyte with its size or independence: Anthoceros has a relatively large and independent sporophyte compared to other bryophytes, but the gametophyte is still the dominant generation.
  2.Overlooking the significance of the chloroplast structure: Focusing on less significant features and missing the key distinguishing characteristic of Anthoceros.
 **Quick Tips**:
  1.Remember the unique characteristics of Anthoceros to differentiate it from other bryophytes.
  2.Use mnemonics or diagrams to remember the key features of different bryophyte groups.
