Scientists think that protists are the oldest eukaryotes. The Endosymbiotic Theory support this opinion.
Humans have collected and grown mushrooms for food for thousands of years.Yeasts are used in bread baking and brewing alcoholic beverages. Other fungi are used in fermenting a wide variety of foods, including soy sauce, tempeh, and cheeses. Blue cheese has its distinctive appearance and flavor because of the fungus growing though it.
protists can inflict harm, particularly to humans. Most harmful protists are classified as animal-like protists that act as parasites, or organisms that benefit from causing harm to other organisms. Malaria is caused by plasmodium which is a kind of protists.
Fungi that are pathogens are usually plant pathogenic Fungi. There are comparatively few species that are pathogenic to animals, especially mammals. the diseases because of fungi are some of ringworm diseases.
Fungi reproduce by spores. Mainly, spores are single-celled, though they are the most simple reproduction organelles. Asexual reproduction occurs when there is a favorable environment for fungi to grow. Sexual reproduction happens when the environment is not favorable for reproduction. However, most fungi reproduce by asexual reproduction.
sexual: two protists exchange DNA Therasexual: binary fission
Fungi are nonmotile. However, the fungal mycelium can grow quickly in any direction if it is in a suitable environment.
Most protists have motility. Protists have three types of appendages for movement. They may have flagella, cilia, or pseudopods (“false feet”). There may be one or more whip-like flagella. Cilia are similar to flagella, except they are shorter and there are more of them.
Fungi join bacteria as the primary decomposers in different ecosystems. They feed on the organic remains of dead plants. Without the various types of fungi on Earth, we would soon be knee-deep in dead leaves that refused to rot. Besides, Many animals eat them, they are good for us.
They play a fundamental role in the decomposition of dead organic matter produced by plants. On the other hand, some of them are predator. ( they eat plants )
They get the energy they need to live from other organisms.
Some protists contain chloroplasts, they can use photosynthesis to make their own food, also there are others that are heterotrophs and obtain their food by absorbing it from their surroundings. But there are some that can do both autotrophic and heterotrophic methods of obtaining food.
Fungi are found in all ecological niches so it is difficult to identify a single set of growing conditions for all fungi. Most of them prefer to live in wet and dark areas.
Protists are found in waters and moist areas, such as in the photo above. Some protists are extremophiles, meaning they can survive in harsh or extreme habitats.
The cell type of fungi and protists is "eukaryotic cell", they are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Plants and animals also have this type of cells.
