Options

A. Egg producing structure is flask shaped in mosses
B. Egg producing structure is oogonium in Chara
C. Female gametangium is archegonium in red algae
D. Male gametangium is antheridium in bryophytes

Answer

To determine which statement is incorrect among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The first statement claims that the egg-producing structure is flask-shaped in mosses.
- In mosses, the female reproductive structure is indeed called archegonia, which is flask-shaped and produces eggs.
- **Conclusion:** This statement is **correct**.

2. **Analyze the Second Statement:**
- The second statement states that the egg-producing structure is oogonium in Chara.
- In Chara (a type of green algae), the female gametangium is called the nucleolus, which is also referred to as oogonium.
- The male gametangium is called globule.
- **Conclusion:** This statement is **correct**.

3. **Analyze the Third Statement:**
- The third statement claims that the female gametangia is archegonium in red algae.
- Archegonia is indeed found in bryophytes, but in red algae, the female gametangium is not archegonium; it is called corpogonium.
- Therefore, this statement is incorrect.
- **Conclusion:** This statement is **incorrect**.

4. **Analyze the Fourth Statement:**
- The fourth statement indicates that the male gametangia is antheridium in bryophytes.
- In bryophytes, the male gametangium is indeed called antheridium, which is club-shaped.
- **Conclusion:** This statement is **correct**.

### Final Conclusion:
The incorrect statement among the options is the **third statement**: "female gametangia is archegonium in red algae."
