The correct Answer is:
To determine which statements regarding Chara are incorrect, let's analyze each statement one by one: 1. **Statement I: A multicellular green alga** - Chara is indeed a multicellular green alga. It belongs to the group of green algae and is characterized by its multicellular structure. - **Conclusion**: This statement is correct. 2. **Statement II: Sex organs are multicellular** - In Chara, the sex organs (antheridia for male and archegonia for female) are indeed multicellular structures. - **Conclusion**: This statement is correct. 3. **Statement III: Male and female flowers develop on the same plant - monoecious** - This statement is incorrect. Chara is dioecious, meaning that male and female reproductive organs are found on separate plants. Therefore, male and female flowers do not develop on the same plant. - **Conclusion**: This statement is incorrect. 4. **Statement IV: Antheridium lies below the level of the archegonium** - In Chara, the male sex organ (antheridium) is positioned below the female sex organ (archegonium). This is a correct anatomical feature of Chara. - **Conclusion**: This statement is correct. **Final Assessment**: The only incorrect statement is Statement III. ### Final Answer: The incorrect statement regarding Chara is: **(III) Male and female flowers develop on the same plant - monoecious.** ---
