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.

Where contractile vacuoles are located in amoeba?
contractile vacuoles merge with the cell membrane..
What are the senses organelle of a protozoa?
There are many sensory organs.Simple eyes,compound eyes,gravity spots etc
Freshwater Paramecium must have a contractile vacuole to regulate water intake and prevent cell lysis due to the hypotonic environment. In contrast, ocean-dwelling Paramecium face an isotonic environment that does not require active regulation of water intake or expulsion, therefore they do not need a contractile vacuole.
How do diseases caused by protozoa differ from diseases caused by bacteria?
Diseases caused by protozoa are generally single-celled organisms that can infect humans and animals, such as malaria and amoebic dysentery. Bacterial diseases are caused by microscopic organisms capable of reproducing on their own, like tuberculosis and pneumonia. While both can cause illnesses, the treatment and prevention methods for protozoal and bacterial diseases may differ due to their distinct biological characteristics and mechanisms.
An amoeba is a unicellular, genderless organism that belongs to the Protista kingdom & can reproduce through asexual reproduction.
Amoeba are the unicellular, microscopic organism which moves by the help of pseudopodia (false foot)
Economic importance of paramecium?

Does phenoxymethylpenicillin cure trichomoniasis?
No, phenoxymethylpenicillin is not effective for treating trichomoniasis. Trichomoniasis is caused by a protozoan parasite and is typically treated with antibiotics such as metronidazole or tinidazole. It is important to consult a healthcare provider for proper diagnosis and treatment of trichomoniasis.
An amoeba cell eats other unicellular organisms like paramecium, bacteria, and plant cells. Some are even parasitic! Amoeba cells eat by moving its cytoplasm (also called pseudopods) around its prey. The prey is literally inside the amoeba now. The Amoeba forms a vacuole around it and breaks it down for nourishment and absorbs it through its cytoplasm.
Any organism that moves by means of pseudopodia (false feet) is called an amoeboid. Amoeboids are a branch of protozoans, but there are porotzoans that are not amoeboids. The answer to your question is that some protozoa (amoeboids) have pseudopodia (false feet), but the rest do not.
What is the difference between Amoeba and Paramecium?
paramecium- move with cilia
amoeba- move by creeping along with their pseudopod's
also, paramecium are larger.
What does Chloroplast do in a Euglena?
Chloroplasts in Euglena help carry out photosynthesis, where they convert sunlight into energy for the organism. They contain chlorophyll, a pigment that absorbs light and plays a key role in this process.
Does Rubidium have health benefits to humans?
Some research suggests that rubidium may have potential health benefits by regulating blood pressure, improving heart health, and supporting nerve function. However, further studies are needed to fully understand its effects on human health. It is important to consult with a healthcare professional before using rubidium supplements.
How do you catch brain eating amoebas?
Brain eating amoebas, Naegleria fowleri, are microscopic. They live in warm water, like runoff water from power plants, mud puddles, and warm lakes. They can live in temperatures up to 115º F.
However, amoebas cannot survive in salt water or treated water.
Amoebas enter the body through the nose, usually when swimming in untreated water. Amoebas travel up the nerve that is responsible for smell, from the nose to the frontal lobe of the brain. They feed on the brain, and release enzymes that dissolve brain tissue.
Keep in mind, infection from brain eating amoebas are very rare.
What are two different characteristics of protozoa?
Characteristics of protozoa:
motility: cilia, flagella, pseudopod
unicellular
heterotroph
Are protozoa prokaryotes or eukaryotes?
Protozoa are eukaryotic.
A cell on the basis of organisation of its nucleus can be of two kinds:
1.PROKARYOTIC
2.EUKARYOTIC
PROKARYOTIC CELL: in prokaryotic cell [unorganised nucleus] no nucleus is present; instead a ring like nucleic acid DNA is present. it is also termed as nucleoid. all cell organelles are absent except ribosomes. Examples: bacteria, blue green algae.
EUKARYOTIC CELL: in eukaryotic cells a true nucleus is present. A true nucleus has four parts namely: nucleolus, nuclear membrane, nuclear reticulum, nucleoplasm. All cell organelles are present in a eukaryotic cell. Examples: amoeba, spirogyra.
Can protozoa live in host cells?
Yes, in fact there are two hosts that they require to live, but I'm not sure what they are
No, an amoeba does not have a heart. Amoebas are single-celled organisms that do not possess a circulatory system like more complex organisms. They rely on diffusion to transport nutrients and gases within their cell membrane.
Why add methyl cellulose to a wet mount with living Paramecium cells?
slows down the organism and makes them easier to observe under a microscooe
What is function of gullet in paramecium?
The gullet in Paramecium functions to take in food particles through phagocytosis and transport them to the food vacuole for digestion. It helps with the ingestion of food and plays a critical role in the feeding process of the organism.
What is the definitive host of Plasmodium?
Plamodium vivax is a unicellular eukaryote. It is a heterotrophic organism that attacks red blood cells. This organism is asexual. The Plamodium vivax lives in it's host's body and stays in the blood stream.
