Which one of the following statement is incorrect for mosses ?

Options

A. Predominant stage of the life cycle is the gametophyte
B. Spore germinates into leafy stage with multicellular rhizoids
C. Vegetative reproduction occurs by budding in the secondary protonema
D. The have an elaborate mechanism of spore dispersal

Answer

To determine which statement is incorrect for mosses, we will analyze the options provided based on our understanding of mosses and their characteristics.

### Step-by-Step Solution:

1. **Identify the Classification of Mosses**:
- Mosses belong to the phylum Bryophyta. They are non-vascular plants, meaning they do not have specialized tissues (xylem and phloem) for water and nutrient transport.

**Hint**: Remember that mosses are classified under Bryophyta and are non-vascular.

2. **Examine the Life Cycle of Mosses**:
- The predominant stage in the life cycle of mosses is the gametophyte stage, which is haploid (1N). This stage is typically the most visible part of the moss.

**Hint**: Focus on the life cycle stages of mosses, particularly the dominance of the gametophyte stage.

3. **Analyze Each Statement**:
- **Statement 1**: "The predominant stage of the life cycle is gametophyte."
- This is correct.
- **Statement 2**: "Spores germinate into leafy stage with multicellular rhizoid."
- This is incorrect. Spores first germinate into a structure called protonema, which does not initially have multicellular rhizoids. Multicellular rhizoids develop later.
- **Statement 3**: "Vegetative reproduction occurs by budding in the secondary protonema."
- This is correct as mosses can reproduce asexually through budding.
- **Statement 4**: "They have an elaborate mechanism of spore dispersal."
- This is also correct, as mosses can disperse spores through various mechanisms including water and wind.

**Hint**: Carefully evaluate each statement against known facts about mosses.

4. **Identify the Incorrect Statement**:
- Based on the analysis, the second statement is incorrect because it inaccurately describes the germination process of spores in mosses.

**Hint**: Look for discrepancies in the descriptions of moss life stages and structures.

### Conclusion:
The incorrect statement regarding mosses is: "Spores germinate into leafy stage with multicellular rhizoid."
