The antherozoids of Bryophytes possess :-

Options

A. 2-Flagella
B. 1-Flagella
C. Multiflagella
D. No-flagella

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They are often referred to as the amphibians of the plant kingdom because they require water for reproduction.

2. **Gametophyte Dominance**: In bryophytes, the main plant body is the gametophyte, which is haploid (having a single set of chromosomes). This structure is responsible for producing gametes.

3. **Male Sex Organ**: The male sex organ in bryophytes is called the antheridium. This organ is multicellular and jacketed, meaning it is surrounded by a layer of protective cells.

4. **Sperm Production**: Within the antheridium, there are sperm mother cells (also known as spermatogenous cells). These cells are haploid and undergo mitosis to produce sperm cells, which are also referred to as antherozoids.

5. **Swimming Mechanism**: Antherozoids need to swim through water to reach the female reproductive structure known as the archegonium for fertilization. To achieve this, they possess flagella.

6. **Flagellation**: The antherozoids of bryophytes are multi-flagellated, meaning they have multiple flagella that aid in their movement through water. This is essential for successful fertilization.

7. **Conclusion**: Therefore, the correct answer to the question is that the antherozoids of bryophytes possess multi-flagella.

**Final Answer**: The antherozoids of Bryophytes possess multi-flagellated structures.
