Which one of the following is wrong about Chara

Options

A. Gobule is male reproductive structure
B. Upper oogonium and lower round antheridium
C. Globule and nucule present on the same plant
D. Upper antheridium and lower oogonium

Answer

To determine which statement about Chara is incorrect, we need to analyze each option provided:

1. **Globule is a male reproductive structure**: This statement is correct. In Chara, the male reproductive structure is known as the globule or antheridium.

2. **Upper Oogonium and lower Antheridium**: This statement is incorrect. In Chara, the female reproductive structure (oogonium) is located above the male reproductive structure (antheridium). Therefore, the correct arrangement is that the oogonium is upper and the antheridium is lower.

3. **Globule and Nucleol present on the same plant**: This statement is correct. Chara is homothallic, meaning that both male (globule) and female (nucleol) reproductive structures can be found on the same plant.

4. **Upper Antheridium and lower Oogonium**: This statement is incorrect. As mentioned earlier, the antheridium (male) is located lower than the oogonium (female).

Based on the analysis of the statements, the incorrect statement is:

**Correct Answer**: The second option, "Upper Oogonium and lower Antheridium," is wrong because the correct arrangement is that the upper part is the oogonium and the lower part is the antheridium.
