Select the option with incorrect satement

Options

A. Bryophytes produce gametes by mitosis
B. Haploid spores are produced by diploid sporophyte throgh meiosis
C. Life cycle of Sprogyra is haplodiplontic
D. Ulothrix shows zygotic meiosis

Answer

To solve the question of selecting the option with the incorrect statement, we will analyze each statement provided in the options.

### Step-by-Step Solution:

1. **Examine the first statement: "Bryophyte produces gametes by mitosis."**
- In bryophytes, the dominant phase is the gametophyte, which is haploid. Gametes (sperm and eggs) are produced by mitosis in the gametophyte. This statement is **correct**.

2. **Examine the second statement: "Diploid spores are produced by diploid sporophyte through meiosis."**
- In bryophytes, the sporophyte is diploid and produces haploid spores through meiosis. This statement is also **correct**.

3. **Examine the third statement: "The life cycle of Spirogyra is haplodeplontic."**
- Spirogyra is an alga that exhibits a haplontic life cycle, meaning it primarily exists in the haploid state. It does not have a diploid sporophyte stage. Therefore, this statement is **incorrect**.

4. **Examine the fourth statement: "Ulothrix shows zygotic meiosis."**
- Ulothrix is a green alga that undergoes zygotic meiosis, where the zygote undergoes meiosis to produce haploid spores. This statement is **correct**.

### Conclusion:
The incorrect statement is the third one: "The life cycle of Spirogyra is haplodeplontic."

### Final Answer:
The option with the incorrect statement is the third statement.
