Protozoa

Entamoeba histolytica is found worldwide, with higher prevalence in tropical and subtropical regions with poor sanitation and hygiene practices. It is commonly found in areas with overcrowding, inadequate sanitation, and limited access to clean water. Infections are more common in developing countries.

Paramecium bursaria primarily feeds on algae, which it ingests through a structure called the cytostome. They can also engage in mutualistic relationships with the algae by harboring them within its cells and benefiting from their photosynthetic activity.

Some protozoans can be dangerous to humans, such as those that cause diseases like malaria and Giardiasis. However, not all protozoans are harmful, and many play important roles in ecosystems as part of the food chain.

Protozoa that move by means of a whiplike organ called a flagellum are known as flagellates. The flagellum propels the organism through its environment by waving back and forth, allowing it to swim and navigate through water. Flagellates can be found in a variety of environments, including freshwater, marine, and soil habitats.

Non-motile protozoa rely on external forces for movement, such as water currents or host organisms. These protozoa typically lack structures like flagella or pseudopods that enable independent movement. Instead, they may adapt by attaching to a surface or living as parasites within a host.

Yes, euglenas are capable of photosynthesis, so they can make their own food using sunlight, carbon dioxide, and water. Additionally, they can also absorb nutrients from their environment when sunlight is not available.

Amoebas help humans by playing a role in breaking down organic matter in the environment, which helps in the recycling of nutrients. They also serve as food sources for various organisms in aquatic ecosystems, contributing to the overall food web. However, some species of amoebas can also cause diseases in humans if ingested or come into contact with open wounds.

Euglena, as a genus of unicellular flagellate protists, have three methods of nutrition. The first is holozic, which is the ingestion of solid food. The second is saprophytic. This is the absorption of foods. The last is holophytic which uses chemical elements for foods.

False. Protozoa are not part of the Plant kingdom, they are classified in the Kingdom Protista.

Conjugation in Paramecium is important for genetic diversity. It allows for the exchange of genetic material between individuals, leading to new genetic combinations and variations in the population. This genetic diversity can increase the chances of survival and adaptation to changing environments.

Food is stored in food vacuoles within an amoeba. When an amoeba engulfs food particles through phagocytosis, the food vacuole forms around the ingested material. Enzymes then break down the food inside the vacuole for digestion.

Amoebas were discovered in 1757 by August Johann Rösel von Rosenhof, a German naturalist. He observed and described them in his work "Insecten-Belustigung" as tiny creatures with constantly changing shapes.

Pretty sure its paramecium (phyla - ciliophora)

Their shells are the most complex and have an outer layer called a pellicle that contains defense structures called trichocysts. (just reading it from my textbook)

Amoebas are found in the phylum Protozoa within the kingdom Protista. They are commonly found in freshwater environments, soil, and marine habitats. Amoebas are known for their ability to move and feed by extending their cell membrane.

Paramecium utilizes a process called diffusion to respire. Oxygen enters through the cell membrane, while waste products like carbon dioxide exit the cell through the same process. This allows Paramecium to exchange gases with its environment and maintain its metabolic functions.

Correct, a pellicle is not found on amoeba. Amoebas are single-celled organisms that do not possess a fixed structure like a pellicle, which is a tightly packed layer of proteins just beneath the cell membrane found in some other types of single-celled organisms.

Protozoa that move by hairlike projections are known as ciliates. They have numerous hair-like structures called cilia that beat in a coordinated manner to propel the organism through its environment. Ciliates are found in various aquatic habitats and are known for their complex behaviors and feeding strategies.

Salt affects the rate of the contractile vacuole in a paramecium by altering the osmotic pressure of the surrounding environment. An increase in salt concentration outside the paramecium causes water to move out of the cell by osmosis, leading to a faster contraction of the vacuole to expel excess water. Conversely, a decrease in salt concentration outside the cell results in slower contractions as less water is being expelled.

The largest amoeba species is the Gromia sphaerica, where individual cells have been found to reach sizes of up to 4 centimeters in diameter.

Protozoa are basically protists. They are NOT animals or plants; they are often considered as a separate kingdom.

It definitely can. An example of a plant protist would be the algae that can photosynthesize. An amoeba or paramecium would be animal like protists and the slime molds would be in the fungus like category of protists.

The tiny spheres inside the larger sphere of Volvox are individual cells called "gonidia." These cells are responsible for photosynthesis and producing energy for the organism. They are interconnected by cytoplasmic strands and work together to enable Volvox to carry out essential functions.

The fastest moving protozoan is probably the Euglena, which can move at speeds of up to 55 micrometers per second using its flagellum.
