Protozoa

Protozoa can enter the body through various routes such as ingestion of contaminated food or water, inhaling airborne cysts, or transmission through insect bites. Once inside the body, they can infect various tissues and organs, causing symptoms of disease.

Pregnant women can be exposed to Toxoplasma gondii by consuming undercooked or raw meat, handling contaminated soil while gardening, or coming into contact with cat feces. It's crucial for pregnant women to take precautions by avoiding risky foods and tasks that may increase the risk of toxoplasmosis.

The disadvantages of euglena are mostly related to its structure and the fact that there is a debate that never ends on whether it is a plant or animal. The lack of routine genetic analysis is the main disadvantage.

Volvoxis the most developed in a series of genera that form spherical colonies. Each mature Volvoxcolony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein. The cells swim in a coordinated fashion, with distinct anterior and posterior poles. The cells have eyespots, more developed near the anterior, which enable the colony to swim towards light. The individual algae in some species are interconnected by thin strands of cytoplasm, called protoplasmates.[4] They are known to demonstrate some individuality and working for the good of their colony, acting like one multicellular organism. The flagellates on its outside resemble Euglena.

One of the major and the most visible differences between prokaryotes, i.e., bacteria, and eukaryotes, i.e., everything else, is the presence of a membrane bound nucleus containing the DNA. Eukaryotes have other membrane bound organelles such as chloroplasts and mitochondria and prokaryoutes do not. However, some bacteria have structures called microcompartments that are enclosed by a different type of membrane.

The disease is known as amoebic dysentery or amebiasis when caused by Entamoeba histolytica. When caused by a bacillus infecting the colon, it is referred to as bacillary dysentery or shigellosis. Both conditions can present with symptoms such as diarrhea, abdominal pain, and blood in the stool.

Euglenas are single-celled protists. They are unique as they can be both autotrophs (make their own food like plants) and heterotrophs (obtain their food from outside sources like animals). Euglenas have a mouth that takes in the food. The food is encapsulated into a vacuole by a process called phagocytosis. Digestive enzymes are sent into the vacuole and when the food is broken down, the nutrients are absorbed into the cell. Undigested waste is eliminated through exocytosis. This is the most rudimentary digestive system among living things.

paramecium prefer anal

stentor prefer oral

Protozoa possess various organic systems, including a specialized feeding apparatus such as cilia or flagella for capturing food, a contractile vacuole for osmoregulation, and a primitive nervous system for responding to environmental stimuli. They also have a digestive system to break down and absorb nutrients and a reproductive system for reproduction.

Plasmodium vivax moves with the help of vector mosquitoes, specifically Anopheles mosquitoes, which transmit the parasite to humans through their bites. Once inside the human host, the parasite infects red blood cells and causes malaria.

what adjectives describe a single celled protozoan?

Methylene blue can inhibit the growth and reproduction of paramecium by disrupting cellular respiration and other metabolic processes. It interferes with the electron transport chain in mitochondria, affecting energy production in the cell and ultimately leading to its death.

Trophozoites are the active, feeding, and reproducing form of protozoan parasites and many species can form resistant cysts. When the cysts are ingested, the parasite is transmitted to a new host

Undigested food is eliminated via cytopyge while water and other wastes through contractile vacuole .

Paramecium have cilia to help them move through water and to direct food particles towards their mouth. The cilia also play a role in sensing the environment and aiding in reproduction by helping in the process of conjugation.

It is simple One Type of the Cilia is used for moving of the paramecium and the other type of Cilia is used for the "sweeping in" of food particles.I hope this helped i am only a young 13 year old studying to become a scientist, well your welcome, bye.

Volvox algae are green in color and appear as spherical colonies of individual cells that are connected to each other by thin strands. Each colony can contain hundreds or thousands of cells arranged in a single layer along the surface. They have flagella that allow them to move through water in a rolling fashion.

Paramecium expels excess water by contracting its contractile vacuole, a specialized structure that accumulates and pumps out water from the cell. This helps maintain the proper internal environment and osmotic balance within the cell.

Amoeba belongs to the class Sarcodina within the phylum Amoebozoa.

Trichomoniasis is a sexually transmitted infection caused by a parasite and is typically transmitted through sexual contact. It is unlikely to be transmitted through sharing a washcloth, as the parasite does not survive long outside the body.

Micronuclei are small nuclei found in some cells, typically formed during cell division. They are important for maintaining genetic material integrity, and their presence can indicate DNA damage or chromosomal instability in a cell. Micronuclei are often used as a biomarker for genotoxicity in cells exposed to harmful substances or radiation.

Yes

Euglena is a protist with characteristics of both plants and animals. It can photosynthesize like plants using chloroplasts, but can also ingest food like animals using a primitive mouth structure called a stigma. Additionally, Euglena has a flagellum for movement.
