Which one of the following is wrong about Chara?
Correct answer: C. Upper antheridium and lower oogonium
- A. Upper oogonium and lower round antheridium
- B. Globule and nucule present on the same plant
- C. Upper antheridium and lower oogonium
- D. Globule is the female reproductive structure
Explanation
c) : All species of Chara reproduce sexually and show highly advanced oogamy. The sex organs are the most distinctive features of the Order Charales and are the most complicated among the hallophytes. Male and female gametangia are called antheridia and oogonia respectively. Male fructification (cluster of antheridia) is called globule and the female is nucule. They are borne at the nodes of short branches, globule towards lower side and nucule (female structure) towards upper side.
