WebDiatoms are microscopic unicellular, colonial, or filamentous algae found in marine and freshwater ecosystems as well as in brackish water, soil, or even on moist surfaces. Diatom’s protoplast, containing recognizable golden-brown chloroplasts, is enclosed in a distinguished cell wall called a frustule (Fig. 8.9 ). WebOther characteristic features of Kingdom Protista are as follows: These are usually aquatic, present in the soil or in areas with moisture. Most protist species are unicellular organisms, however, there are a few multicellular protists such as kelp. Some species of kelp grow so large that they exceed over 100 feet in height.
