They can live in a symbiotic relationship with algae, like blue-green algae. Later in the year 1866, the term protista was coined by Ernst Haeckel. The basis of his classification is the cell structure, mode, and source of nutrition and the structure of the body. These are neither plants nor animals or bacteria. The kingdom contains organisms that do not meet the characteristics of living things. Sexual reproduction is by conjugation, transformation, and transduction. The growth rate of fungi is slower than that of bacteria. Characteristics of Protists Protists as a group have very little in common. Fungi have cell wall made up of cellulose or chitin. Many protists also form colonies. These organisms are not plants, animals, bacteria, or fungi.
