They are free-living, non-parasitic, and inhabit fresh or saltwater bodies. Thus, ciliates (and, most likely, other protists) may play the role of transient reservoirs for bacteria outside their preferred multicellular host,' concludes the scientist. Ciliates often have two kinds of nuclei that have different functions. No: What's feeds on paramecium? Still others reproduce by making asexual spores, which spread out and form new individuals.Plant-like protists reproduce asexually (A) or sexually (B) when haploid gametes (C) fuse to form a diploid zygote (D).

Although unicellular, ciliates also communicate with other cells, for example, with invading or symbiotic micro-organisms, some of which are dwelling in the nuclei. Ciliates are found in. Phylum Ciliophora. Slime mold cells may also clump together to form . Although capable of swimming, it prefers to . A. because the organism vary tremendously from one to another, as they do not have shared evolutionary origin. Green algae are predominantly found in freshwater environments, though a small number of species are also found in the ocean. A. motile procaryotic unicellular protist. The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella.
