Protists are unicellular or multicellular microorganisms. The majority of protists are responsible for many diseases in humans.

What does amoeba eat?

Amoebas primarily feed on bacteria, algae, and other small particles found in their environment. They engulf their food using pseudopods, which are extensions of their cell membrane that surround and engulf the food particles.

What are seaweed and diatoms called?

Its a type of algae .

PS: take note, diatom is also a type of algae. the major difference that you can observe between a diatom and a seaweed is their size. Diatom is a microalgae(microscopic in size) and seaweed, is a macroalgae(can be observed by the naked eye).

How does and amoeba use energy?

An amoeba gets energy in the same way that you do - from its food. An amoeba feeds by sending out 'bulges' of its cytoplasm, called pseudopodia, to surround a small food particle eg a smaller protozoan or an alga. The food, together with a small drop of the water is taken into the cell to become a food vacuole. Enzymes are then added to the food vacuole to digest the food. The soluble products of digestion are taken into the cytoplasm and used for respiration or growth. The release of energy from food is called respiration. Usually, the sugar called glucose is used by cells. Respiration usually involves 'burning' the food with oxygen. When this happens water and carbon dioxide are also produced: glucose + oxygen ---> water + carbon dioxide + ENERGY For a number of interesting articles about amoebae with photographs, go to: http://www.microscopy-uk.org.uk/full_menu.html Select Miscape article library, click on the Find icon and enter amoeba into the search box.

What are the only multi cellular protists?

The only type of multicellular protists are plant-like seaweeds known as algae. There are three different types of algae that are differentiated by color. The brown algae is known as Phaeophyta, the red algae is known as Rhodophyta, and the green algae is known as Chlorophyta.

What kingdom is blepharisma in?

blepharisma are found it bacteria

Unique characteristics of amoeba?

They are easily overlooked since they are transparent and often resemble decaying organic remains. Amoebas have lobe-shaped psuedopodia and are soil-dwelling fresh water or marine. The cytoplasm inside the cell is capable of changing into different states. It is able to turn from a fluid state plasmasol, to a more solid state plasmagel. A clever trick of the amoeba is they seem to use different engulfing tactics to suit various types of prey. They detect if a prey needs a fast approach (ciliates) or can be feasted on as a slow meal (immobile algae). Another amazing featture of the amoeba is when disturbed the amoeba proeus will change into a shape like a star. This allows it to free float in the water. These are just a few differences I could come up with maybe someone else can elaborate more:)

What part of an amoeba helps it capture food?

food vacuole is a small cavity in the cytoplasm that temporarily store food.

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.

What color are blepharisma?

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.

Does an amoeba have a spine?

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 .

Where is the cell amoeba found?


The Ameoba lives in the mud and water of ponds and ditches.

Why can amoeba get so large?

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.

Is a protist a pathogen?

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
