The ciliates are also capable of undergoing sexual and asexual reproduction. Ciliates carry out a sexual process referred to as conjugation, which is the source of genetic diversity. The diatoms primarily carry out asexual reproduction (by binary fission), and sexual reproduction in these algae is relatively rare.When they do reproduce sexually, it involves the formation of sperm and eggs. I hope this helps!he diatoms primarily carry out asexual reproduction (by binary fission), and sexual reproduction in these algae is relatively rare.

There are many possible causes of a swollen tongue. A swollen tongue can result from such abnormal processes as infection, inflammation, allergy, genetic disorders, trauma, malignancy and metabolic diseases. Some causes of a swollen tongue are serious, even life-threatening, such as a anaphylactic reaction.
A black or brown tongue typically is due to the overgrowth of bacteria that normally are present on the tongue. This, too, can be caused by the killing of some bacteria with antibiotics so other bacteria overgrow. But the most common cause of discoloration of the tongue is the overgrowth of a fungus. The most common fungus is called candida. But overgrowth of the candida fungus turns the tongue white. Infection with candida is called candidiasis, and when it happens on the tongue the condition is called thrush.
