Morphology

Long, cylindrical, bilaterally symmetrical unicells with blunt ends. Ring-like thickening in the central area where the two semicells join. In a good specimen, very delightful to look at due to obvious intracellular activity, especially at the ends.

Reproduction

Asexual: cells arise from the partitioned parent cell

Sexual: Conjugation (transmission of DNA through nucleus fusion to form a hypnozygote or zygospore, which is a term for a zygote that lies dormant until optimal conditions arise)

gollark: Tired of managing coroutines yourself? Try the potatOS coroutine manager, Polychoron.
gollark: My site is definitely not that popular.
gollark: There was a minor bot issue.
gollark: I didn't put much thought into it.
gollark: I don't know. Weird design quirk.
