Protozoa

No. The smallest infective particle is a protein called a prion.

Euglena (and other protists) are Eukaryotic

Amoeba are eukariyotic cells.So they have mitochondria.

Paramecium bursaria is a mixotroph, meaning it can photosynthesize like a plant by hosting green algae within its cells, while also feeding on organic matter like other heterotrophs. This combination allows it to derive energy from both sources, enhancing its nutritional versatility.

Yes, a Paramecium is an open system because it interacts with its environment by exchanging energy and matter. It takes in nutrients and releases waste products to maintain its internal environment.

Paramecium in canal water serve as a food source for larger organisms like fish and invertebrates. They also help regulate the population of bacteria and algae through grazing, contributing to the overall balance of the aquatic ecosystem.

No, a paramecium is a single-celled organism classified as a protist. It is unicellular and does not have specialized cells that form tissues or organs, making it different from multicellular organisms.

A producer, because it has a chloroplast to make its own food using photosynthesis.

Euglena is pronounced yoo-glee-nuh.

The hair-like structures on a protozoa are called cilia. Cilia are short, numerous, and hair-like projections that help in movement and feeding in protozoa. They are used for locomotion by beating in a coordinated manner.

The contractile vacuole helps regulate osmotic pressure by pumping out excess water that enters the cell. Paramecium lives in freshwater environments where osmotic pressure fluctuations can be harmful. The contractile vacuole is critical for maintaining proper internal water balance and preventing cell bursting.

No, a paramecium is not a bacteria cell. A paramecium is a type of single-celled organism known as a protist, while bacteria are single-celled prokaryotic organisms. They differ in terms of cell structure, classification, and other characteristics.

Amoebas move by using structures called pseudopods, which are temporary protrusions of their cell membrane that form in the direction they want to move. They extend and contract these pseudopods to push themselves forward in a process known as amoeboid movement.

Plasmodium, the parasite that causes malaria, can disrupt the equilibrium of human populations by causing high rates of illness and death, particularly in areas with limited access to healthcare and resources. This can lead to decreased productivity, increased healthcare costs, and strain on local economies, ultimately impacting the overall stability and growth of the population.

No, amoebas do not have hair. They are single-celled organisms that lack specialized structures like hair. Their shape can change as they move and engulf food through a process called phagocytosis.

No, a biosphere refers to the entire ecosystem of a certain area, including all living organisms and their interactions. Humans, mosquitoes, and Plasmodium (the parasite that causes malaria) are only a small part of a larger biosphere.

Humans, mosquitoes, and Plasmodium together would be considered a host-pathogen-vector system for malaria transmission. Mosquitoes act as vectors by transmitting the Plasmodium parasite from one host (humans) to another through their bites. Plasmodium is the causative agent of malaria, a disease that affects humans.

active transport, the water is pushed out through contractile vacuoles against its natural flow. Osmosis states that water flows from a higher concentration to a lower concentration, but the paramecium has less water and water is still being pushed out.

The flagellum whips back and forth and propels the Euglena.

Imagine the flagellum to be something like a flag and it just keeps waving allowing the organism to move.

Or, you can also imagine the way butterfly stroke is performed in swimming. The flagellum moves in that way and propels the Euglena.

yes and no. they are pathogenic because they harm and they arent pathogenic because they dont always harm and instead sometimes provide benefit to the host

Protozoa are single-celled organisms that contain animal-like characteristics but are not considered true animal cells because they exist as individual organisms rather than as part of a multi-cellular animal. Additionally, Protozoa belong to the kingdom Protista, which is separate from the animal kingdom.

Actually it has more similarities to horseshoe crabs, ticks and mites, but it is not an ancestor of these creatures either. It is most likely a cousin of the ancestor of these creatures. http://www.austmus.gov.au/palaeontology/research/trilobites02.htm

Flagellates are single-celled organisms that have whip-like flagella for movement. In lakes and streams, flagellates play a critical role in the food chain as both primary producers and consumers. They can photosynthesize like plants or feed on smaller organisms like bacteria, algae, and other protists.

Trichomoniasis is an infection caused by the parasite Trichomonas vaginalis, not a disease. It is a common sexually transmitted infection (STI) that can cause symptoms such as vaginal discharge and itching. Treatment typically involves antibiotics.
