Chromista reproduction
WebPythium dissotocum is a polycyclic oomycete root rot capable of both sexual and asexual reproduction. In its mid-season asexual phase, P. dissotocum disperses by forming filamentous sporangia, which produce vesicles housing 10-75 motile zoospores.

Ciliates reproduce asexually, by various kinds of fission. During fission, the micronucleus undergoes mitosis and the macronucleus elongates and undergoes amitosis (except among the Karyorelictean ciliates, whose macronuclei do not divide). The cell then divides in two, and each new cell obtains a copy of the micronucleus and the macronucleus. Typically, the cell is divided transversally, with the anterior half of the ciliate (the proter) forming o… WebHow do chromists reproduce? both sexual and asexual (alternate between 2) Why do evolutionists believe that all life came from prokaryotic cells they want to deduce …
