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.

What are the similarities and differences between and elodea cell and a paramecium cell?

the difference between an elodea cell & an paramecium cells, are that elodea cells can't survive on it's own because it is not a single celled organism and it has to work together with other elodea cells to survive. While paramecium cell on the other hand are single celled organisms and have everything that they need to live on their own

Are amoebas motile?

Amoebas use pseudopods (false feet in Latin) to move around. They strech out one part of themsleves then pull the rest of it toward the part. The streched part looks like a limb, resulting in "false feet."
Locomotion in amoeba is due to the formantion of pseudopodia formation. PSEUDOPODIA: it is the out growth of amoebic cell plasma forming a buldge known as "ZONE OF GELATION". Several theory have been given for the formation of pseudopodia in which sol-gel theory is most acceptable.
amoeba move my changing their body shape they form pseudopod

the defenation of pseudopod is a false or temporary foot
Amoeba moves with the help of pseudopodia(false feet). It uses cytoplasmic streaming
Amoebas move with false feet. They stretch one part of their body and pull the rest of it with them. Sort of like a stretch and pull.

How is euglena similar to plants and animals?

Euglena is similar to plants because it contains chlorophyll and can perform photosynthesis to produce its own food. It is similar to animals because it can also ingest food particles and is capable of movement using a whip-like structure called a flagellum.

What are characteristics of chlamydomonas?

Chlamydomonas is a unicellular green alga with two flagella for movement. It can perform photosynthesis and reproduce both sexually and asexually. Chlamydomonas is commonly used in research as a model organism for studying various biological processes.

Why is euglena dangerous?

Euglena is typically not considered dangerous to humans. However, in some cases, certain species of euglena can produce toxins that may harm other aquatic organisms or disrupt ecosystems. Additionally, large blooms of euglena in water bodies can have negative impacts on water quality and aquatic life.

Is Entamoeba histolytica gram positive or gram negative?

Bacteria are gram positive and gram negative (which means if you apply Gram stain to them, they either pick up the color (positive) or they do not (negative). Entamoeba Hystolytica is not a bacteria, it is a protozoa (one celled organism) that usually causes diarrhea and can be diagnosed from a stool sample and treated with drugs.

What disease does the sporozoan plasmodium cause?

The sporozoan Plasmodium causes malaria, a potentially life-threatening disease transmitted through the bites of infected mosquitoes. It infects red blood cells and can lead to symptoms such as fever, chills, and flu-like symptoms. If left untreated, malaria can be fatal.

What does plasmodium vivax look like?

Plasmodium vivax is a protozoan parasite that infects red blood cells. It has a ring stage and mature stage with amoeboid morphology. It can be identified under a microscope by its characteristic appearance within red blood cells.

What removes excess water in a paramecium?

A contractile vacuole in a paramecium removes excess water by collecting and expelling it from the cell. This process helps regulate the osmotic pressure within the cell to prevent it from bursting due to excess water intake.

What disease does Entamoeba cause?

Entamoeba species, such as Entamoeba histolytica, can cause a disease called amoebiasis. It can lead to a range of symptoms, including diarrhea, abdominal pain, and in severe cases, dysentery and liver abscesses. Treatment usually involves antibiotics to eliminate the parasite.

How does a paramecium respond to a cotton fiber?

A paramecium will typically swim away or around the cotton fiber using its cilia to sense and navigate its surroundings. It may also secrete enzymes to try and break down the fiber if it perceives it as a potential food source.

Why cant the paramecium change shape like the ameba?

Paramecium have a rigid outer covering called a pellicle that limits their ability to change shape. Amebas, on the other hand, have a more flexible cell membrane that allows them to change shape easily in order to move and feed.

What is the scientific name for the phylum Protozoa?

The scientific name for the phylum Protozoa is Protozoa.

What is the IQ of an amoeba?

Amoebas do not have IQ in the same way that humans do. They are single-celled organisms without a brain or complex nervous system, so they do not possess intelligence in the same sense that higher-order animals do.

What is an example of a flagellated protozoan?

Trypanosoma brucei is a flagellated protozoan that infects African the tsetse fly. The tsetse fly then acts as a vector to spread the disease "African trypanosomiasis" to humans and animals.

Which organism moves faster amoeba or paramecium and why?

Paramecium moves faster than amoeba because it has cilia, tiny hair-like structures that beat rapidly to propel the organism through the water. Amoeba, on the other hand, moves by extending its pseudopods, which is a slower form of movement compared to cilia.

What are the traits of amoeba?

Amoebas are single-celled organisms that move and consume food by extending pseudopods, or temporary bulges in their cell membrane. They reproduce asexually through binary fission and do not have a fixed shape, allowing them to change their body shape to move and capture prey. Amoebas are typically found in freshwater environments and play a role in nutrient cycling in ecosystems.

What side effects do humans have from protozoan?

Protozoan infections in humans can cause a range of symptoms including diarrhea, fever, nausea, abdominal pain, and fatigue. Severe cases can lead to more serious complications such as respiratory distress, dehydration, and organ failure. Treatment for protozoan infections often involves medications to target the specific type of parasite causing the illness.

Habitat of non pathogenic amoeba?

Non-pathogenic amoebas are commonly found in various aquatic environments such as freshwater bodies like lakes, ponds, and rivers, as well as in soil. They play important roles in nutrient cycling and decomposition processes in these habitats. Several species also form symbiotic relationships with other organisms.

Do amoebas have ribosomes?

Yes,they have ribosomes.Almost every cell have them.

Why are euglena and volvox found near surface of water?

Euglena and Volvox are typically found near the surface of water because they rely on sunlight for photosynthesis. Being closer to the surface allows them to receive more sunlight, which is essential for their energy production. Additionally, these organisms also need access to oxygen for respiration, which is more readily available at the water's surface.

What is the Scientific name for flagellated protozoan?

The scientific name is given to flagella can be in three main categories. They include bacterial flagella, eukaryotic flagella and archaeal flagella. As a matter of fact, flagella is a scientific name.
