Green algae with many cells is called Chara. In Chara, sexual reproduction is oogamous.

The male sex organ is a golden, globular structure known as the antheridium or globule.

The female sex organ, also known as the oogonium or nucule, is an oval, green structure.

The majority of Chara species are monoecious, meaning that both globules and nuclei are found on the same plant. 

 

At the nodes, globule and nucleus are both present, with globule located beneath the nucleus, i.e., oogonium is present in the upper portion and antheridium in the lower portion.

Therefore, of all the claims presented, "Upper antheridium and lower oogonium" is false.
