Select an incorrect statement about bryophytes ?

Options

A. They may possess root-like, leaf-like or stem-like structures
B. Zygotes undergo reduction division immediately
C. Some cells of the sporophyte undergo reduction division ( meiosis) to produce haploid spores.
D. They lack true roots, stem or leaves

Answer

To determine the incorrect statement about bryophytes, we will analyze the characteristics and life cycle of these plants step by step.

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are a group of lower plants that include mosses and liverworts. They are often referred to as the amphibians of the plant kingdom because they require water for their sexual reproduction.

2. **Characteristics of Bryophytes**:
- Bryophytes do not have true roots, stems, or leaves. Instead, they have root-like structures called rhizoids. This means that they can anchor themselves but do not have the complex structures found in higher plants.

3. **Life Cycle of Bryophytes**:
- Bryophytes exhibit a haplodeplontic life cycle, which includes both haploid (gametophyte) and diploid (sporophyte) stages. In this cycle, the zygote does not undergo reduction division (meiosis) immediately.

4. **Meiosis in Bryophytes**:
- In bryophytes, meiosis occurs in the sporophyte generation, not in the zygote. The sporophyte produces haploid spores through meiosis, which then develop into gametophytes.

5. **Evaluating the Statements**:
- **Statement 1**: Bryophytes are known as amphibians of the plant kingdom. (Correct)
- **Statement 2**: Zygote undergoes reduction division immediately. (Incorrect)
- **Statement 3**: Sporophyte has reduction division (meiosis) to produce haploid spores. (Correct)
- **Statement 4**: They lack true roots, stems, and leaves. (Correct)

6. **Conclusion**:
- The incorrect statement about bryophytes is that the zygote undergoes reduction division immediately. This is not true, as meiosis occurs in the sporophyte, not in the zygote.

### Final Answer:
The incorrect statement about bryophytes is: "Zygote undergoes reduction division immediately."
