Which one of the following is incorrect 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 halophytes. Male and female gametangia are called antheridia and oogonia, respectively. Male fructification (cluster of antheridia) is called a globule, and the female is a nucule. They are borne at the nodes of short branches, globule towards the lower side and nucule (female structure) towards upper side

These protists are mostly unicellular (a few are colonial) organisms with spherical or elongated bodies with a single central nucleus. They possess one to many long, whip-like flagella that enable them to move. Flagellates move rapidly, pulling themselves forward by lashing flexible flagella, that are usually located at the anterior end. Examples include Trypanosome, Euglena, etc. The above lines indicate which of the following groups of protozoa:
