Protists

No, amoebas are not plants. They are single-celled organisms belonging to the group Protists. Amoebas are known for their ability to move and feed by extending their cell membrane in a process called phagocytosis.

Protists can reproduce sexually or asexually, depending on the species. Asexual reproduction methods include binary fission, multiple fission, and budding. Sexual reproduction typically involves the fusion of gametes from two different individuals.

Yes, amoebas can reproduce by fragmentation. During fragmentation, the amoeba divides into two or more parts, each of which develops into a new individual.

Paramecium has a rigid outer covering called a pellicle that gives it its shape, while euglena's shape is maintained by a proteinaceous structure called the pellicle and supported by protein strips called microtubules underneath the cell membrane.

The more than 8,000 species of diatoms are the largest group in the phylum Chrysophyta of the kingdom Protista.

Yes they do. It is beneath the Si frustule and used in diatom defence against copepods. Check out Pohnert and Ianora's work on aldehyde production from polyunsaturated fatty acids in the lipid cell membrane.

They have two flagellum one longer than the other. The larger moves in a whip like manner and propels the organism forward and the other flagellum acts as a rudder to steer the organism in the direction it wishes to travel.

Trichocyst is a very small bottle-shaped structure found in paramecia that is used for defense. When a paramecium senses a threat, it discharges the trichocysts to release long, sharp structures that can deter predators or capture prey.

It is a type of protozoa.They have eukariyotic cells

There are several varieties found in humans that are not considered to be disease producers. However, such virulent strains as Entamoeba coli and Entamoeba hartmanni, can produce mild diarrhea and dysentery. Most amoeba infestations, however, do not produce clinical symptoms.

I Don't Known the special awnser

Diatoms are very important in both freshwater and marine ecosystems. They export excess carbon in the ocean and also utilize silic acid to create their cells walls. The use of this also helps them be controlled vicariously through the abundance and dispersal of it throughout the water.

Diatoms are also able to sink, so that helps them with dispersal.

They are responsible for nearly half of the ocean's energy production.

The protist that has two nuclei is Paramecium. It has a large macronucleus involved in regulating cellular functions and a smaller micronucleus involved in sexual reproduction.

The process in which 2 paramecium join to exchange DNA is called conjugation. During conjugation, the micronuclei of the paramecia undergo meiosis to exchange genetic material, leading to genetic diversity in the offspring.

Dinoflagellates appear as single-celled organisms that have a distinct shape, with two flagella that they use for movement. Depending on the species, they can have different shapes ranging from spherical to elongated or even armored with plates. Under a compound microscope, their cell structures and any photosynthetic pigments they contain can be visible.

Blepharisma disintegrates and dies when exposed to intense artificial light due to the damage caused to its cell membrane and organelles by the high energy photons. This damages the cell's ability to maintain proper function and leads to its eventual disintegration and death.

Heterotroph: eats bacteria from decaying plants

Protists are similar to bacteria in that they are both single-celled organisms. However, protists are eukaryotic, meaning they have a nucleus and other membrane-bound organelles, while bacteria are prokaryotic. Additionally, some protists are capable of photosynthesis like bacteria, but protists overall exhibit more complex cellular structures and functions.

Amoeba feeds on small microorganisms like bacteria, algae, and other tiny protozoans by engulfing them through phagocytosis. Paramecium feeds on bacteria, algae, and other small organisms by sweeping them into its oral groove using cilia, forming a food vacuole that digests the food.

Yes, most protist cells have a nucleus. This nucleus contains the genetic material of the cell and is surrounded by a nuclear membrane. There are some exceptions, such as red algae, which have a nucleomorph instead of a traditional nucleus.

No, not all protists have cell walls. Some protists have cell walls made of various materials like cellulose or silica, while others do not have cell walls at all. The presence or absence of a cell wall depends on the specific type of protist.

Domain: Eukaryota Kingdom: Amoebozoa Phylum: Tubulinea Order: Tubulinida Family: Amoebidae Genus: Amoeba

Paramecium caudatum is not a disease-causing organism. It is a species of free-living ciliate protozoan found in aquatic environments, commonly used in biological studies as a model organism for research purposes.

No, a worm is not a protist. Worms are part of the animal kingdom, specifically belonging to the phylum Annelida or Nematoda depending on the type of worm. Protists are a diverse group of microorganisms that include various single-celled eukaryotes like amoebas and algae.
