Protists
Protists are unicellular or multicellular microorganisms. The majority of protists are responsible for many diseases in humans.

Where can you find a picture of an animated amoeba?
You can find one in the "Prentice Hall" microbiology science book.
Response:
You can find an animated gif [http://huntertrek.com/wp/wp-content/uploads/2008/02/amoeba.gif here]
Negative chemotaxis, which refers to the movement of an organism away from a chemical stimulus. In this case, the paramecium is exhibiting a negative response by moving away from the chemical added to the microscope slide.
Are diatoms freshwater marine or both?
Diatoms can be found in oceans, freshwater, and also in soils on damp surfaces
What does the cytoplasm do in amoeba?
In an amoeba, the cytoplasm functions as a medium for various cellular activities, such as nutrient storage, waste disposal, and movement of organelles. It also plays a role in maintaining cell shape and supporting cellular functions.
It is a heterotroph, which means it makes its own food. "Autotroph" mean that it makes its own food.<-- old answer
corrected answer: It is a heterotroph, which means it doesn't makes its own food. It must consume other heterotrophs or autotrophs. "Autotroph" mean that it makes its own food
What is the macronucleus and micronucleus in paramecium?
The macronucleus is larger and controls all functions except reproduction. The micronucleus is smaller and controls reproduction. Some paramecium have more than one micronucleus, but all have at least one.
What does it mean that dinoflagellates bloom?
When dinoflagellates bloom, it means there is a sudden and rapid increase in their population. This can lead to the water appearing discolored or "red tide," which can have negative impacts on marine ecosystems and human health.
Are the amoeba and the cactus and the fern and the moss and the tree related?
Yes, the amoeba, the cactus, the fern, the moss, and the tree are related in being living organisms. But no, the amoeba isn't as closely related to the cactus, the fern, the moss and the tree as the last four are to each other.
The amoeba is a one celled microorganism whose scientific classification differs quite a bit from that of the cactus, the fern, the moss, and the tree. It's in the domain of eukaryotic organisms that have a nucleus. It's in the amoeba kingdom, Amoebozoa.
In contrast, the cactus, the fern, the moss, and the tree are all members of the plant kingdom, Plantae. Within that kingdom, the cactus and the tree are related as members of the division of flowering plants, Magnoliophyta. The fern is a member of the vascular division, Pteridophyta, because of neither flowering nor seeding. The moss is a member of the non vascular division, Bryophyta.
How does a amoeba gather food?
An amoeba gathers food through a process called phagocytosis, where it surrounds and engulfs its food, such as bacteria or algae, with its cell membrane to form a food vacuole. Enzymes are then released into the vacuole to digest the food, allowing the amoeba to absorb the nutrients.
What is a feature that a virus bacteria and protist have in common?
actually your wrong im also in 7th grade science they are both a single celled organism
If The nucleus of an amoeba is removed the organism can not carry out?
If the nucleus of an amoeba is removed, the organism cannot carry out essential functions such as cell division, DNA replication, and protein synthesis. The nucleus contains the genetic material, including the instructions for these processes, without which the amoeba cannot survive.
Are there protists in the Alaskan tundra?
Yes, there are protists in the Alaskan tundra. Protists are a diverse group of eukaryotic microorganisms that can thrive in extreme environments like the tundra due to their adaptability and resilience. They play important roles in nutrient cycling, food webs, and overall ecosystem function in tundra ecosystems.
What is the difference between a paramecium and a stentor?
paramecium prefer anal
stentor prefer oral
What do plasmodium vivax move with?
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.
During unfavorable conditions an ameba forms a?
During unfavorable conditions, an amoeba forms a protective outer covering called a cyst. The cyst allows the amoeba to survive harsh conditions such as lack of water or extreme temperatures. Once conditions improve, the cyst can break open and the amoeba can resume its normal activities.
What are symptoms you get from protists?
Symptoms of infection by protists can vary depending on the specific type of protist. Common symptoms can include diarrhea, abdominal pain, fever, nausea, vomiting, and muscle aches. Some protists can also cause more serious conditions such as malaria or giardiasis.
How does methylene blue affect the paramecium?
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.
Single-celled organisms like the amoeba are neither coldblooded nor warmblooded because they don't have blood. The cell absorbs its nutrients and excretes its waste products directly through its cell wall into the environment. Complex multicellular organisms need a means of moving food in and waste out and so developed blood as a transport mechanism.
Some protists are heterotrophs, meaning they obtain nutrients by ingesting organic matter. Others are autotrophs, capable of producing their own food through photosynthesis. Additionally, some protists can switch between both feeding mechanisms depending on environmental conditions.
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.
Why do paramecium have 2 types of cilia?
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.
How does paramecium expel water?
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.
Explain how protists differ from other organisms?
All protists are eukaryotic (have a nucleus), most live in water. They are the "ancestor organisms" because they were the first organisms ever to exist.
Protists are simply organisms that don't fit into any of the other kingdoms.
The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes. This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction. Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.
