carpogonium
Quick Summary
The carpogonium is the egg-bearing part of the female reproductive organ in certain types of red algae. In the complex life cycles of red algae, such as Polysiphonia, the female gametophyte produces special carpogonial branches that bear carpogonia, which are the female gametes. Fertilization occurs when a male gamete, called a spermatium, fuses with the carpogonium. This fusion initiates the development of the zygote and subsequent stages in the red algae's reproductive cycle.12

red algae…female sex organ, called a carpogonium, consists of a uninucleate region that functions as the egg and a trichogyne, or projection, to which male gametes become attached. The nonmotile male gametes (spermatia) are produced singly in male sex organs, the spermatangia.
