Protozoa

The cells in a volvox colony are connected to one another by strands of cytoplasm, enabling them to coordinate movement. When the colony moves, cells on one side of the colony "pull" with their flagella, and the cells on the other side of the colony have to "push."

A chlamydomonas cell or Chlamydomonas reinhardtii,is a single celled green alga about 10 micrometers in diameter that swims with two flagella. They have a famous "Eye spot" which senses light. This cell is used as a "test cell" in many labs for simple tests like ours involving DNA and many other things.

Hepatocytes release Plasmodium gametes when infected with the parasite, which eventually bursts to release the gametes into the bloodstream.

The protozoan parasite associated with AIDS that can lead to pneumonitis, hepatitis, and encephalitis is called Toxoplasma gondii. It is an opportunistic infection commonly seen in individuals with compromised immune systems, such as those with late-stage AIDS. Treatment typically involves a combination of anti-parasitic medications.

A paramecium obtains food by using its cilia to force water down into the gullet. Particles that enter the gullet are then forced into cavities called food vacuoles.

The digestive enzymes in the food vacuoles then digest the food particles

The plural form of protozoan is protozoa.

The protozoa that are not capable of independent movement are called "sporozoans." They are parasitic organisms that rely on a host to move from one place to another.

The protozoa that are not capable of independent movement are called sporozoans. They are parasitic protozoa that typically have complex life cycles involving multiple hosts. Examples include Plasmodium, the parasite responsible for causing malaria, and Toxoplasma gondii, which causes toxoplasmosis.

It appears that trichomoniasis is one of the few STDs that can be caught through other means as well. Although the protozoan dies rapidly in dry conditions, it appears that you can be infected by sharing a washcloth with an infected person, or possibly by having your genitals come into contact with someone else's infected genital discharge.

Euglena, like all other cells, are enclosed by a plasma membrane, contain genetic material in the form of DNA, and are capable of performing basic cellular functions such as metabolism and reproduction.

When an amoeba eats, the food vacuole organelle will help store the food particles that have been ingested. Additionally, lysosomes will aid in digesting the food within the food vacuole by releasing enzymes to break down the food into smaller molecules for absorption.

Acanthamoeba keratitis is a rare but serious eye infection caused by a free-living amoeba found in the environment. Symptoms include severe eye pain, redness, blurred vision, sensitivity to light, and feeling like something is in the eye. Risk factors include contact lens use, poor contact lens hygiene, and exposure to contaminated water sources. Early diagnosis and treatment are essential to prevent complications and vision loss.

Yes, Balantidium coli is a single-celled protozoan parasite that can cause gastrointestinal infections in humans.

Yes, trichomoniasis and bacterial vaginosis (BV) can sometimes be mistaken for each other because they can have similar symptoms, such as abnormal vaginal discharge. However, they are caused by different pathogens - trichomoniasis is a sexually transmitted infection caused by a parasite, while BV is an overgrowth of certain bacteria in the vagina. Proper testing by a healthcare provider is necessary to accurately diagnose and treat each condition.

Amoebas move relatively slowly compared to larger organisms. They use pseudopods, which are temporary bulges of the cell membrane, to propel themselves forward by constantly changing their shape. This allows them to move in a slow, crawling manner.

No, Plasmodium falciparum, the parasite that causes malaria, does not have flagella. It has a specialized organelle called the apical complex, which helps it invade host cells.

Chlamydomonasis a genus of green algae consisting of unicellular flagellates. Chlamydomonasis used as amodel organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogenesis, and genetics. One of the many striking features of Chlamydomonasis that it contains ion channels that are directly activated by light, such as channelrhodopsin. Some regulatory systems of Chlamydomonasare more complex than their homologs in Gymnosperms, with evolutionary related regulatory proteins being larger and containing additional domains [1].

Yes, some protozoa can cause disease in humans and animals. These microscopic organisms can be responsible for various illnesses such as malaria, giardiasis, and toxoplasmosis. Preventative measures like practicing good hygiene and using insecticide-treated bed nets can help reduce the risk of protozoal infections.

An amoeba is a type of single-celled organism that moves and feeds by using pseudopods, or temporary bulges of the cell. They are found in various aquatic and terrestrial environments and play essential roles in the ecosystem as decomposers and as a food source for other organisms.

Some amoebas are parasitic, meaning they live inside another organism and obtain nutrients at the host's expense. However, not all amoebas are parasitic, as there are many free-living species that feed on bacteria and algae in various environments.

Actually protozoa are divided into groups according to their form of locomotion. They include flagellates, amoeboids, and ciliates. Flagellates have one or more whip-like organelles that are used to move around. Amoeboids have extensions of eukaryotic cells that expand and contract, causing locomotion. Ciliates have hair-like extensions around. The hair-like extensions are similar to flagellates' whip-like extensions but are much shorter and finer.

The eyespots allow the volvox to find and take in the much needed light to perform photosynthesis, which provides the volvox food to survive.

Avoidance behavior in a paramecium is when the organism moves away from stimuli that may be harmful or unfavorable, such as a sudden increase in temperature or the presence of toxins in its environment. This movement helps the paramecium survive and thrive in its habitat by enabling it to escape potentially dangerous situations.

Amoeba feeds on some microscopic organisms. When it senses food, it pushes out pseudopodia around the food particle and engulfs it. The food becomes trapped in a food vacuole. Digestive juices are secreted into the food vacuole. They act on the food and break it down into simpler substances. Gradually the digested food is absorbed. The absorbed substances are used for growth, maintenance and multiplication. The undigested residue of the food is expelled outside by the vacuole.
