Why has the Kingdom Protista been abandoned?
Advances in systematics have caused the kingdom Protista to crumble. the former kingdom is paraphyletic: some protists are more closely related to plants, fungi, or animals than to other protists. {& plants are a problem: sister clade to "green algae" - but not included in "protists"}
As a result, the kingdom Protista has been abandoned ... Biologists still use 'protist 'informally,
{like 'reptile' or 'dog'} as a convenient way to refer to eukaryotes that are neither plants, animals, nor fungi.
Blepharisma are typically pink in color, ranging from light pink to dark pink. This color comes from specific pigments in their cells, such as hemoglobin and carotenoids.
No, an amoeba is an invertebrate since it does not have any spinal bone structures or any bones at all.

Why is kingdom Protista so unique?
Protists are extremely important in ecological and medical research. In medicine, certain protists are used to study the relationship between chromosomal structure and aging. Muticellular protists such as slime molds provide valuable insight about the chemical signals used in more complex organisms to coordinate cellular activity.
What are characteristics all protists share?
The word "protozoon" is a catch-all for any single-celled eukaryote. That's all they have in common; they've got a nucleus. "Protozoa" is an archaic taxon, and over the years has since been split into various other kingdoms including Amoebozoa, Excavata, Rhizaria, and more.
How does a paramecium move from one place to another?
A paramecium moves by using hair-like structures called cilia, which beat in a coordinated manner to propel the organism through water. It can change direction by altering the pattern of cilia movement. The movement of a paramecium is often described as being "graceful" due to its smooth and gliding motion.
Why protist have traditionally been placed in theit own taxonomic kingdom?
Protozoan (protista) are prokaryotes. They do not have membrane organelles such as the nucleus. Eukaryotes (plants, animals, fungi) do have the membrane bound organelles including the nucleus. Pro-means before, -kary- means "nut" (nucleus). Prokaryotes are earlier forms of life (before the "nut"). Eu- means new so a "new nut" (nucleus).
Identify the diatomic element in this group?
The seven diatomiic elements are hydrogen, nitrogen, oxygen,flurine,chlorine, iodine,bromine is known as diatomic elements .
Well, the amoeba is a very complicated type of cell life form. An Amoeba does not go through a well planned diet, so they get much larger then other cells. Amoeba's basically eat anything they can find or die trying.
What are the negative effects of protists?
Protists can cause diseases in humans, animals, and plants. For example, malaria is caused by a protist called Plasmodium. Additionally, some protists can disrupt ecosystems by outcompeting native species for resources.
Yes they can. Famous ones are Plasmodium the agent of Malaria or trypanosoma species the agents of sleeping illness or chagsa disease
Do protists have cilia or flagella?
Yes
A flagellum, also called undulipodium, is a whip-like structure used for locomotion, for feeding or other purposes. Almost all organisms have flagella to include protozoa (at some stage in their lives). We humans have them in our bodies. Even our own spermatozoa can be regarded as flagellates. All these flagella have a similar basic design. flagellum, also called undulipodium, is a whip-like structure used
How are protists used in foods?
cheese, sour cream, other dairy products and seawed,tea,some types of icecream,toothpaste,and yougurt
How do protists protect themselves?
Animals protect themselves by:1. Camouflaging themselves or imitating other animals
2. Releasing smells or liquids that bother predators
3. Injuring enemies with hard thorny body parts.
4. By simply biting, scratching and other defensive attacks.
Some examples include bristles, spines, and stingers; stink glands; body or wing coloration used as camouflage.
camouflage
What is an illness caused by protist?
Entamoeba histolytica, one of those amoebic protists, and he can only complete his life cycle in our guts. It's mostly those with undeveloped immune system that die.
Giardia lamblia is one of those protists that more resembles animals than amoebas. And it is also a lovely protist that infects 10% of US population alone! Mostly causing diarrhea.
The plasmodium causes non other than Malarya! Again, mostly guts issues. (Beginning to see a trend?)
Trypanosoma , a blood parasite, cause sleeping sickness, and they can be fatal.
So....you know...try to avoid them. Stay clean. Stay healthy.
Yes, diatoms are autotrophs because they can photosynthesize to produce their own food using sunlight, carbon dioxide, and other nutrients. They are a type of algae that play a significant role in marine and freshwater ecosystems.
No, amoebas are unable to photosynthesize. They are heterotrophic organisms that obtain their energy by consuming other organisms or organic matter. Photosynthesis is a process carried out by autotrophic organisms like plants and algae to produce energy from sunlight.
Where could I find paramecium Euglena and Amoeba?
It should be fairly easy to find paramecia in freshwater ponds, and basically any other mass of fresh water, especialy those with lots of water plants in them, Euglena is just the group of protists they are in. You can find amoebas in exactly the same kind of places, but the amoeba is slightly more sensitive to pollution, so you are less likely to find it in polluted areas.
Plantlike protists are considered to be?
Plants are like protist in that they have a relatively simple organization.
fungi protects the algal partner from stronge light and desiccation in this way it gets food by the coutesy of alga.
