Question

Which one of the following is wrong about Chara?

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

Answer 1

The Correct Option is B

In this question, we are asked to identify the incorrect statement about Chara, a genus of green algae. Let's analyze each option to determine the correct answer:

1. Globule and nucule present on the same plant: This statement is correct. In Chara, both reproductive structures, globule (male) and nucule (female), are found on the same plant.
2. Upper antheridium and lower oogonium: This is the incorrect statement. In Chara, the typical arrangement is that the antheridia (male reproductive organs) are located below the oogonia (female reproductive organs). Therefore, this statement is reversed.
3. Globule is male reproductive structure: This statement is correct. In Chara, the globule is indeed the term used for the male reproductive structure (antheridium).
4. Upper oogonium and lower round antheridium: This statement is correct. As previously mentioned, the correct arrangement in Chara is that the oogonium is above the antheridium.

The incorrect statement is option 2: "Upper antheridium and lower oogonium." This is because the actual arrangement in Chara is that the antheridium (male) is below the oogonium (female).
