give me some explanation on the subject topic please give me replies

I think this Forum allows teaching and learning so let's learn together. This site shows pictures of the filament fusion that ocurs during Spirogyra mating. Isogamy seems to indicate that the sixe and appearance of the gametes is pretty much identical right? And that isogamy involves a significant size difference between gametes (like human sperm and egg). Well, take a look at the pictures and see what you think.

Of course I meant anisogamy for sperm and egg
