Which one of the following is wrong about Chara?

Chara is a multicellular green alga. Sexual reproduction in Chara is oogamous. The male sex organ is a spherical structure which is yellow in color and is called antheridium or globule. The female sex organ is oval-shaped, green-colored structure and is called oogonium or nucule. Most species of Chara are monoecious, i.e., globule and nucule are present on the same plant. Globule and nucule are present at the nodes with globule present below the nucule, i.e., oogonium are present at the upper portion and antheridium is present at a lower portion. Hence, statement 'Upper antheridium and lower oogonium' is incorrect among all the given statements.
