Protista is a single-celled organism with a very simple cellular structure. It is one of Robert Whittaker’s five kingdoms, which he presented in 1969. Antoni van Leeuwenhoek discovered it in pond water 300 years ago. The basic unit of the food chain is the protist. It is a eukaryote with a membrane-bound nucleus that thrives in a damp environment since it has no methods of stopping itself from drying out.
Fungi are a separate kingdom of multicellular eukaryotic or prokaryotic organisms that lack chlorophyll. We are continually exposed to mushrooms through the air we breathe, the food we consume, and the water we drink since there are millions of different fungi that share our environment. Yeasts, rusts, smuts, mildews, moulds, and mushrooms are examples of this.
Fungi were thought to be the first to evolve from Protists after the evolution of Monerans and Protists. The Kingdom Fungi contains around 100000 species.
Protista
Protista is a single organism that transforms into a group to become a protist. Protists, like protozoa, fungus, and algae, are a kingdom or group of diverse organisms with a unicellular or single-cell structure. In 1866, German biologist Ernst Haeckel coined the name Protista.
Aquatic creatures that contain eukaryotic protists, which are not genuine animals, plants, or fungus, are known as protists. A multicellular stage is not present in all protists. Movement is done via appendages such as cilia or flagella in some of these creatures.
Characteristics 0f Protista
- Protists are varied creatures with few characteristics in common
- Organisms that aren’t categorised as plants, animals, fungi, or bacteria are known as protists (prokaryotes)
- Eukaryotic protists are simple in structure and have a nucleus
- Members of the Protista kingdom have more similarities than differences, as evidenced by how they differ from members of other kingdoms
- It doesn’t have a predetermined shape
- Protists come in a variety of forms
- Protists do not require nourishment
- They devour other species, their parts and products, and the remains of other organisms, or they create their own food through chloroplast
Fungi
Moulds, yeasts, mushrooms, and toadstools are examples of fungi that produce spores and feed on organic matter. The Kingdom Fungi (or Mycota) is a multicellular, eukaryotic, and heterotrophic nourishment group of living things. Fungi are mainly found as saprobiotics for parasites.
Fungi have a wide range of shapes and habitats. Fungi are among the most extensively dispersed creatures on the planet, and they play an important role in both the environment and medicine.
Characteristics of Fungi
- The vegetative phase of a fungus is referred to as thallus, and it does not have distinct roots, stems, or leaves
- The thallus of Saccharomyces cerevisiae or Yeast can be unicellular or filamentous, like in other fungi
- The thallus is made up of many fine, tubular, thread-like filaments known as hyphae (sin. hypha)
- The hyphae can be either a septate (without walls) or septate (with walls) (with walls)
- Multinucleated hyphae are found in a septate hyphae (coenocytic)
- Fungi are cosmopolitan in that they can be found almost anywhere
- The majority of fungi are terrestrial, although a few are also aquatic
- Fungi thrive in warm, humid environments such as wood, tree bark, dung, and so on
Association of Fungi with Other Organisms
Fungi are frequently found in beneficial interactions with other creatures. Lichens are a symbiotic relationship between algae and fungi that play a critical part in ecosystem development. Mycorrhizae are fungi that form symbiotic relationships with the roots of higher plants. The absorption of nutrients from the soil is aided by these fungi.
Protists and Fungi: Difference
|
Protists |
Fungi |
|
They are mostly Unicellular |
They are mostly multicellular |
|
In this case, some contain a cell wall and some do not contain the wall |
It contains a cell wall made up of Chitin |
|
These are either autotrophs, heterotrophs, parasites |
Heterotrophs |
|
No Septa are found in this case |
Septa, Separating fungal hyphae into parts are found |
|
Generally Protozoans, algae and moulds are the three types. |
There are Seven phyla of fungi |
|
E.g. Green Algae, amoeba |
E.g. It includes yeast, pichia and Eomycota. |
Conclusion
Fungi are one of the most diverse and omnipresent living entities, according to this article. They are achlorophyllous, and their nourishment is both absorptive and heterotrophic. Plants and animals are the ones who suffer the most. Some have a significant economic impact and are even consumed. Some forms have a beneficial relationship with other living organisms and mutually benefit.
