Protozoa
Protozoans are unicellular organisms found in many different habitats. They are eukaryotic and can be predators, herbivores or parasites, depending upon the species. The well-known disease malaria is caused by a protozoa.

Amoebae feed through phagocytosis, a processes which engulfs solid food sources through the cell membrane by use of an internal food vacuole. Amoebas find food with their pseudopods.
amoeba feed by using its pseudopodia . it engulf it foods by phagocytosis. as amoeba is a holozoic organism , it feeds on microscopic organism such as bacteria. the pseudopodia enclose the food and packaged it in a food vacuole. the food vacuole fuses with a lysosome and the food is digested by a hydrolytic enzyme called lysozyme.the resulting nutrients are absorbed into the cytoplasm.
It can't.
Seeing as they are microscopic organisms, I'd assume they eat something small.
Amoeba engulf their food. They change their shape and flow around a particle that they wish to eat. they also use their pseudopod to move and to shape their body around their prey
An amoeba eats by using its "false feet", which is known as pseudopodia.
Amoeba eat other Protists such as Paramecium aka slipper cells, plant cells and bacteria. Amoeba eat by changing their body composition with pseudopods and wrapping itself around it's prey. Pseudo means false and pod means foot.
Amoebas eat bacteria, algae and other protozoa.
How do amoebas get the nutrition they need?
They move around using a foot-like projections called pseudopods. Amoebas also use these pseudopods to capture food.Then creates a food vacuole around the food particle.
What kingdom do ciliates and flagellates belong to?
The taxonomic kingdom Protista is a collection of single-celled organisms that do not fit into any other category. The animal portion of this group are the protozoa.
The protozoa are divided into four major groups: the ciliates, the flagellates, the heliozoans, and the amoebas.
Is trichomonas autotrophic or heterotrophic?
Monerans are organisms that lack a membrane bound nucleus. Some monerans are heterotrophic and obtain their food from the environment. Others, like the cyanobacteria are autotrophic since they are able to create their own food.
How do ciliates differ from other protozoans?
Zooflagellates differ from other protozoans because they are unicellular and may live on their own or on a host as a parasite. They have long bodies with one large nucleus. They reproduce by binary fission.
Not intentionally, for when they do - the virus eats them.
Volvox is a genus of green algae containing around 20 species of freshwater algae. Thousands of cells together form colonies. There are around 500 to 60,000 cells in each colony of volvox. It belongs to Plantae.
It's only dangerous if you are small enough to be eaten by them...i.e. another
single celled animal.
How do ciliates paramecium move?
cilia are tiny hair-like structures that "push" or "row" the organism through a medium. Double check though. I think a paramecium may move using a flagella (a single larger whip-like structure)
Which is a charateristic of a euglena?
Euglena are unicellular organisms, commonly identified by having two flagella and a photoreceptor called and eyespot. Most have chloroplasts, but not all. Euglena's plasma membrane is surrounded by a flexible layer known as the pelicle which can flex to allow for movement.
How do you get trichomoniasis if you or your partner have not been with anyone?
Trichomoniasis is a parasite that lives in the vaginal canal in females, and the urethra in males. It is specifically transferred by sexual contact. If neither partner claims to have it, then neither partner should contract it. If someone has contracted it, then someone else has a lot of explaining to do.
Just like any STD, Trichomoniasis is transmitted during sexual contact, be it penis to vagina, vulva to vulva, or occasionally penile/anal contact. Therefore it is not possible for a partner to spontaneously develop a trichomoniasis infection.
That being said, Trichomonaisis can be asymptomatic in many, or may simply be latent for a period of time and not producing any symptoms.
What is the difference between gonorrrhea and trichomoniasis?
Gonorrhea is a bacterial STD, curable with Rocephin (ceftriaxone). Trichomoniais is caused by a parasitic protozoan, and is curable with Flagyl (metronidazole). Both are spread by sex, but oral or anal infection do not occur with trich, and men don't get trich from having sex with men. Gonorrhea can have long-term consequences if untreated, but trichomoniasis does not.
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.
Why amoeba is an unicellular organisms?
because amoeba is a single cell organism made up of only one cell which helps in the function of vital organs...
How do amoeba achieve locomotion?
Amoeba employs a crawling-like type of movement accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia. The cytoplasm slides and forms a pseudopodium in front to move the cell forward. This type of movement has been linked to changes in action potential; the exact mechanism is still unknown. Locomotion of amoeba occurs due the sol-gel conversion of the cytoplasm
What is the main taxonomic group to which Euglena belongs?
Euglenoids are flagellates, single celled organisms in the Kingdom Protista. Euglenoids belong to the domain eukarya. It doesn't have a cell wall but a protein coat. It as a paramylon carbohydrate reserve. There are 900 species. And it is found in fresh water, polluted and estuary habitats.
How does the amoeba obtain its food?
The amoebae extends two pseudopodia by microtubule extension and surrounds the bacterial prey, then, instead of reeling in the prey, the amoebae drags itself up to the trapped bacteria and then engulfs it by a form of phagocytosis. There the bacteria is digested by many different enzymes designed for the job.
What are the various parts of a paramecium?
Idk... but i need to kow for a project.
So i guess im asking the same question. lol
Protozoa can reproduce through asexual methods such as binary fission, where the cell divides into two daughter cells, or through sexual reproduction, where genetic material is exchanged between individuals. Some protozoa can also reproduce through multiple fission, budding, or sporulation.
Paramecium belongs to the phylum Ciliophora, which is characterized by the presence of cilia used for movement and feeding.
