Where do protists mainly live?
Where do protists mainly live?
Most protists are aquatic organisms. They need a moist environment to survive. They are found mainly in damp soil, marshes, puddles, lakes, and the ocean. Some protists are free-living organisms.
Where is the protist kingdom located?
Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems. Other protists are responsible for a range of serious human diseases, such as malaria and sleeping sickness.
Where do Mixotrophic protists live?
The term zoochlorella (plural zoochlorellae) is sometimes used to refer to any green algae that lives symbiotically within the body of a freshwater or marine invertebrate or protozoan.
How are protists helpful to humans?
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis.
Are bacteria Mixotrophic?
There are also inherent advantages to being mixotrophic. Ciliates and flagellates are not the only organisms that can be mixotrophic; mixotrophy also appears to be very common in multicellular organisms (see, for example, references 62, 82, and 83) and bacteria.
Are Euglenids Mixotrophs?
However, Euglena is a mixotrophic organism (it is a holophytic organism because it produces her own food through photosynthesis in chloroplasts, and it is also a heterotrophic organism because it absorbs elaborated food, i.e. biotic products). Euglena’s eye-spot can detect light.
Which protist is a Mixotroph?
The constitutive mixotrophs, or CM, are photosynthetic organisms that are capable of phagotrophy, also called “phytoplankton that eat” [11]. They include most mixotrophic nanoflagellates (e.g., Prymnesium parvum, Karlodinium micrum).
What makes a protist Mixotrophic?
Mixotrophs are organisms which combine phototrophy and heterotrophy; such nutritional behaviour is widespread among protists. This ability to combine multiple modes of nutrition varies between species and is not related to their taxonomic grouping. In groups B, C and D phototrophy is the dominant mode of nutrition.
