…In red algae, the spores formed through sexual reproduction are called carpospores, and are distinguished from asexually produced spores (tetraspores, monospores, etc.). The zygote produced when an egg cell (the egg cell of red algae is specifically called the carpogonium) combines with a sperm develops within the gametophyte to become a carposporophyte. This carposporophyte eventually produces a carpospore, but the process from fertilization to carpospore formation can be of various types, which is an important characteristic when classifying red algae. … *Some of the terminology that mentions "carposporophyte" is listed below.
