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. The pigments phycocyanin and phycoerythrin are responsible for the characteristic red colouration of the algae. Size: It ranges from 0.2-100 µm. Examples are the diatoms and dinoflagellates that inhabit the oceans and are found at the bases of marine food chains. They are unicellular species which exist individually, or in chains or groups. The microorganisms inhabiting aquatic environments are collectively referred to as plankton; phytoplankton refers to the photosynthetic microbes (primarily algae), … 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. It is possible to appreciate the diseases that can be fought utilizing the secondary metabolites from different types of bacteria. There are two main categories of algae: microscopic single-celled microalgae, and larger, multi-celled macroalgae.

Algae are a wide range of diverse microorganisms that are typically photosynthesis and aquatic. Chapter 2. Some are harmful to man while others are good for man and environment around. Autotrophic microorganisms, such are some bacteria (cyanobacteria) and algae supply aquatic ecosystems with the oxygen they produce in the process of photosynthesis. The mangrove ecosystem is one of the toughest on Earth, and plants in such conditions are known to contain abundant secondary metabolites. Algae, unlike other microorganisms, are photosynthesisers and are typically found in marine environments. Genetic material: The genetic material of bacteria can be either DNA or RNA. Box 3015, 2611AX Delft, The Netherlands Yes, not audible of course, but most things that move also make sounds. The cool thing is, some seem to use it for signaling, here is an example: *... Virus etc. Microorganisms in a cold environment: Ice algae in Antartica. While some lack cell walls, others have scales. For example, the harvesting efficiency of C. vulgaris increased 45–50% when cultivated with Rhizobium radiobacter .

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. Algae are sometimes considered as protists with chloroplasts. Microorganisms-based methods refer to the use of microorganisms. Two types of single-celled organisms currently exist which are prokaryotes and eukaryotes. Algae are eukaryotic, which means they have a nucleus. Microalgae or microphytes are microscopic algae invisible to the naked eye.They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment.

Many species cause such human diseases as malaria, sleeping sickness, dysentery, and toxoplasmosis. The term algae implies a variety of plantlike organisms. In microbiology, several types of single‐celled algae are important. Examples are the diatoms and dinoflagellates that inhabit the oceans and are found at the bases of marine food chains. Algae are very important because they make much of Earth’s oxygen, which humans and other animals need to breathe. They live in water, damp soil, and rocks and produce oxygen and carbohydrates used by other organisms. Stramenopiles have chlorophyll a, chlorophyll c1/c2, and fucoxanthin as photosynthetic pigments.
