Harmful Microorganisms examples: Escherichia coli O157:H7, Mycobacterium tuberculosis, Streptococcus mutans, Salmonella enteric and Chlamydophila pneumonia. Blue-green algae in the soil are present in a wide variety of moist soils, primarily present around the plant root in the form of the symbiotic association. Examples are the diatoms and dinoflagellates that inhabit the oceans and are found at the bases of marine food chains. Algae are sometimes considered as protists with chloroplasts. Autotrophic microorganisms, such are some bacteria (cyanobacteria) and algae supply aquatic ecosystems with the oxygen they produce in the process of photosynthesis. Algae are increasingly hard to characterize groups of living organisms, containing the two prokaryotes and eukaryotes.

Box 3015, 2611AX Delft, The Netherlands Shapes: coccus (spherical or round). There are two main categories of algae: microscopic single-celled microalgae, and larger, multi-celled macroalgae. Streptococcus bacteria. Algae, also called cyanobacteria or blue-green algae, are unicellular or multicellular eukaryotes that obtain nourishment by photosynthesis. An algal bloom is a massive population explosion of free-floating, phototrophic organisms, often composed of dinoflagellates, that usually occurs from an influx of nutrients, specifically nitrogen and phosphorus. Some species of algae release toxic compounds into the water. Not at all like different microorganisms algae are commonly known as green growth and are normally found in marine situations. The cell is the smallest living organism that contains all the features of life, and most of all life on the planet begins as a single-cell organism. These include eukaryotic protists and prokaryotic cyanobacteria, also known as blue-green algae. These organisms might either occur freely in the soil or in the form of symbiotic relationships with plants of lichen-forming fungi. Shape: Bacteria are pleomorphic in nature. Algae are eukaryotic, which means they have a nucleus. Algae and protozoa are examples of protists. They can take inorganic substances and with the help of the sun transform them into organic nourishment. Depending on the species, their sizes can range from a few micrometers (μm) to a few hundred micrometers. They are unicellular species which exist individually, or in chains or groups.

Collectively algae, protozoa, and some lower fungi are frequently referred to as protists (kingdom Protista, also called Protoctista); some are unicellular and others are multicellular. It is possible to appreciate the diseases that can be fought utilizing the secondary metabolites from different types of bacteria. Algae (singular: alga) are plant-like protists that can be either unicellular or multicellular (Figure \(\PageIndex{4}\)). Algae are organisms, or living things, that are found all over the world. Their storage carbohydrate is chrysolaminarin. Nucleus: True nucleus absent. Unlike bacteria, algae are eukaryotes and, like plants, contain the green pigment chlorophyll, carry out photosynthesis, and have rigid cell walls. They normally occur in moist soil and aquatic environments. Algae can exist as single cells, an example of which is Chlamydomonas, or joined together in chains like Spirogyra or made up of many cells, for instance Rhodymenia (red seaweed). But … Algae and protozoa are examples of protists. There are many types of algae. However, these are some of the more prominent types: Also called Rhodophyta, it is a distinctive species found in marine as well as freshwater ecosystems.
