Solution
The correct option is D Upper oogonium and lower antheridium on the same plant
Chara is a genus of green algae and reproduces by both sexual and vegetative modes. Sexual reproduction of Chara is an advanced oogamous type. The sex organs are macroscopic and large.
Most of the species are homothallic or monoecious ( i.e. male and female sex organs develop on the same plant ) but some are heterothallic or dioecious ( i.e. male and female sex organs on different plants ).
Monoecious or homothallic condition in Chara (green algae) is used to denote upper oogonium and lower antheridium on the same plant. The organisms, which possess both the reproductive organs are called bisexual. Unisexual condition represents both male or female organs in same organism.
Thus, the correct answer is option D.
