Protozoa

No, a paramecium does not have legs. Instead, it moves using hair-like structures called cilia that cover its outer surface. These cilia beat in a coordinated manner to propel the paramecium through its environment.

Euglena is primarily aerobic, meaning it obtains energy through aerobic respiration in the presence of oxygen. However, euglena can also switch to anaerobic respiration in the absence of oxygen to generate energy.

Entamoeba is known as Entamoeba histolytica because it is a species of amoeba that is capable of invading and destroying tissues within the host's body, a process known as histolysis. This invasive characteristic sets it apart from other species of Entamoeba.

A contractile vacuole helps amoebae and paramecium regulate the water content within their cells by periodically expelling excess water to prevent them from bursting due to osmotic pressure. Without a contractile vacuole, these organisms would be vulnerable to cellular damage from fluctuations in hydration levels and could potentially die from osmotic stress.

Flagella

Both are motile and have flagella that help them move around.

In waterlily cells, the function of the vacuole is to store nutrients, water, and waste products. In fish cells, the function of the mitochondria is to produce energy in the form of ATP through cellular respiration. In paramecium cells, the function of the contractile vacuole is to regulate water content by pumping out excess water to maintain internal osmotic balance.

The two development stages are Trypanosoma brucei and Trypanosoma cruzi. Trypanosoma brucei, they lived ib the blood stream. it's transmitted by an insect vector. It is mostly associated in Africa. The transmition vector is tsetsefly and it is caused by sleeping sickness. It bites and jnject.

Trypanosoma cruzi also lives in the blood stream. It is an insector vector. It is associated in America. The insect that transmit is reduvid bug or kissing bettle. It causes sleeping sickness.

Amoeba is classified under the kingdom Protista because it exhibits characteristics of both plants and animals. Amoebas are unicellular organisms with a flexible cell membrane that allows them to move and engulf their food like animals, but they lack specialized tissues and organs found in true animals. This unique combination of features places them in a separate kingdom apart from animals.

Volvox are not harmful to the environment because they play a big part in our everyday lives... however if you ate the volvox it would probably make you sick.

Paramecium, like all protists, are single-celled organisms. Cells are the building blocks for all life forms. "Single-celled" means

that a paramecium has only one cell for its entire body. Most plants and animals have more cells than you can count.

Euglenas are able to perform photosynthesis to produce their own food using sunlight. Moving toward sunlight allows them to maximize the amount of light available for photosynthesis, which is essential for their survival and growth.

No, parameciums do not have chloroplasts. They are single-celled organisms belonging to the group of protists, and they are not capable of photosynthesis. Instead, parameciums obtain their energy by feeding on bacteria and other small organisms.

Although Toxoplasma is a protozoa, and has eucariotic cell -> some antibiotics (macrolides) can act on it by blocking expression of apicoplast genes (circular DNA), interfering with 50S ribosomal subunit [procariotic ribosome responsible for expression of apicoplast genes]

They are both producers of food

Amoebas are typically found at the bottom of the food chain as primary consumers. They feed on microscopic organisms like bacteria and algae, playing a vital role in breaking down organic matter and recycling nutrients in ecosystems. Larger organisms then consume amoebas as a food source, continuing the transfer of energy up the food chain.

Amoeba keep their environment moist by constantly taking in water through osmosis to prevent dehydration. They also produce a protective layer called a cyst in response to dry conditions to retain moisture and survive in unfavorable environments.

Cyst formation allows parasitic protozoa to survive in unfavorable environments (such as outside the host), protecting them from harsh conditions. It also facilitates their transmission to new hosts, as cysts are more resistant and can be easily ingested by the host. Additionally, cysts help parasites evade the host's immune system and maintain their population over time.

A paramecium is eukaryotic because it has membrane-bound organelles such as a nucleus, mitochondria, and a complex internal structure. Its DNA is enclosed within a nuclear membrane, and it undergoes the process of mitosis for cell division.

The largest organism is a fungus called Armillaria ostoyae, also known as the "humongous fungus." It covers an area of over 2,385 acres in Oregon's Malheur National Forest.

Preventing the spread of protozoa can be achieved by practicing good hygiene, such as washing hands frequently and thoroughly, especially after using the bathroom or handling food. Avoiding eating or drinking contaminated food and water sources, and properly treating and storing water can also help minimize the spread of protozoa. Additionally, practicing safe sexual practices and avoiding close contact with infected individuals can reduce the risk of spreading protozoa.

Protozoa can be spread through contaminated water sources, such as lakes, rivers, and ponds. They can also be transmitted through the bite of an infected insect, like a mosquito or tick. In some cases, protozoa can be spread through contaminated food or poor hygiene practices.

A dormant resting state of a protozoan cell is known as a cyst. Cysts form as a protective mechanism in response to adverse environmental conditions, allowing the cell to survive until conditions improve. During this stage, metabolic activities are greatly reduced, and the cyst can resist desiccation, extreme temperatures, and other stressors.

Volvox is considered a colonial alga because it consists of numerous individual cells that work together to form a spherical colony. These cells are specialized for different functions, such as reproduction and movement, allowing the colony to function as a multicellular organism despite being made up of individual cells.

The cyst stage allows for the transmission of intestinal parasites from one host to another. These cysts are environmentally resistant and can survive outside the host, facilitating their transfer to a new host through contaminated food, water, or surfaces.
