Solution: Most of the eukaryotic organisms are multicellular, but some organisms are unicellular and they include the members of the Kingdom Protista like Protozoa (Paramoecium), Chrysophytes (Diatoms and desmids), Dinoflagellates (Gonyaulax), Euglenoids (Euglena) and Slime moulds (Physarum). These are the primary inhabitants of salt lakes, inland seas, and evaporating ponds of seawater, such as the deep salterns, where they tint the water column and sediments bright colors. Cells function differently in unicellular and multicellular organisms. One good example of a vector is mosquitos. [2] Halophiles require sodium chloride (salt) for growth, in contrast to halotolerant organisms, which do not require salt but can grow under saline conditions. Which of the following nutritional modes do fungi most commonly utilize? Streptomyces, Escherichia coli, Lactobacillus acidophilus. They are multicellular and are commonly known as sac-fungi.

Microbial Factories: Using Bacteria to Make Specific Compounds. This makes these ancient bacteria very significant in a modern world. [5] Currently, 15 recognised genera are in the family. They are categorized into three groups depending on their morphology and formation processes: Archaebacteria, Eubacteria, and Eukaryote. They live in water, damp soil, and rocks and produce oxygen and carbohydrates used by other organisms. Halophiles are found thriving in habitats with a high concentration of salt, such as in the Great Salt.. Fungi include both unicellular (yeast and molds) and multicellular (mushrooms) organisms. The two kingdoms of unicellular eukaryote organisms are considered to be polyphyletic. Match each organism or group of organisms with its domain.
