Protozoa
Protozoans are unicellular organisms found in many different habitats. They are eukaryotic and can be predators, herbivores or parasites, depending upon the species. The well-known disease malaria is caused by a protozoa.

What kingdom that includes amoeba and paramecium?
The kingdom that includes amoeba and paramecium is Protista. Protists are single-celled organisms that are eukaryotic and have characteristics of both plants and animals. They are typically found in water environments and can have diverse forms and feeding strategies.
How do protozoa affect our lives?
Protozoans play the role of consumers and decomposers in the food chain. Protozoa prey upon unicellular algae, bacteria, and microfungi aiding in pollution control whether organic of chemical.
What is the function of the contractible vacuole in the Euglena?
Contractile vacuoles are found in aquatic protists.They remove excess water.
Volvox is a Chlorophyte, or green alga. It exists as a grand spherical colony. Each little alga within the colony bears two flagella, whip-like hairs. The individual alga are connected to each other by thin strands of cytoplasm that enable the whole colony to swim in a coordinated fashion. The individual alga also have small red eye spots.
The colonies even have what we could call a front and rear end. Or, since Volvox resembles a little planet, a 'north and south pole'. In the northern region the eyespots are more developed. This helps the colony to swim towards the light. This differentiation of cells make Volvox quite unique. It is a colony that comes really close to being a multi-celled organism.
How does a volvox protists capture and release energy?
Volvox protists capture energy through photosynthesis, using sunlight to convert carbon dioxide and water into sugars. These organisms release energy by breaking down these sugars through cellular respiration, which involves the conversion of sugars into ATP, the cell's main energy currency.
What are the 4 major groups of protozoa?
rhizopoda,flagellata,ciliata,sporozoa are four classes of phylum protozoa
Do amoebas have a segmented body?
Nope they dont. Certain types of worms (polychates) have segmented bodies, as do crustaceans (lobsters, crabs, etc) and insects.
What are similarities between Euglena and Ameba?
Both Euglena and Amoeba are single-celled organisms that belong to the Protista kingdom. They both have flexible cell membranes and can move using pseudopods. Additionally, they both obtain nutrition through various methods, such as photosynthesis in Euglena and phagocytosis in Amoeba.
How is a euglena like a plant cellHow is it like an animal cell?
what are some similarities between euglena and plant cells
An amoeba replicates by splitting in half asexually so that each daughter cell is the same as the parent. Running this process backward from the present, each existing amoeba is the same as its predecessor (fungible) back as far in time as the first amoeba existed. In this regard the amoeba is immortal.
Now it get a bit picky.
The above assumes that no genetic changes have occurred since amoeba #1. This cannot be proved. Replication errors, chromosome damage by radiation etc may have happened to create slightly better or worse (at least different) amoebas that are the ancestors of all amoebas today.
The term "immortal" needs some thought to. No individual amoeba is necessarily immortal. Each amoeba can be killed. Only the amoeba pattern is immortal so far.
Then there is the Star Trek transporter problem. When Kirk is transported he is destroyed at the sending end and reconstituted at the receiving end. Is he the same Kirk? Amoebas are the same. The "mother" amoeba is essentially destroyed as it divides to create the daughters. Do the daughters share all the learnings of the mother? or would they see themselves as unique?
What is plant like characteristic of Paramecium?
Paramecium is a group of unicellular ciliate protozoa, which are commonly studied as a representative of the ciliate group, and range from about 50 to 350 μm in length. Simple cilia cover the body, which allow the cell to move with a synchronous motion (like a caterpillar). There is also a deep oral groove containing inconspicuous compound oral cilia (as found in other peniculids) used to draw food inside. They generally feed on bacteria and other small cells. Osmoregulation is carried out by a pair of contractile vacuoles, which actively expel water from the cell absorbed by osmosis from their surroundings.
Paramecia are widespread in freshwater environments, and are especially common in scums. Certain single-celled eukaryotes, such as Paramecium, are examples for exceptions to the universality of the genetic code (translation systems where a few codons differ from the standard ones). Although, some new species of Paramecia have recently been discovered in the oceans
Protozoa are classified according to their what?
Protozoans have four groups of classification. The four protozoan groups are Phylum Ciliphora, Phylum Mastigophora, Phylum Sarcodina and Multicellular animals.
naturalists referred to Amoeba as the Proteus animalcule after the Greek godProteus who could change his shape. The name "amibe" was given to it by Bory de Saint-Vincent,[3] from the Greek amoibè (αμοιβή), meaning change.[4]
What does bacteria have in common with paramecium?
No,Parameacium is not a bacteria but it is a single celled organism which on bacteria
What does the eyespot enable the protozoa to do?
A red eyespot is clearly visible. In fact the real light sensitive organ is the swelling near the base of the flagellum. The red area makes sure only light from one direction is detected. Since the light sensitive organ is directly connected to the flagellum, Euglena is perfectly able to swim towards a light source
What organelles function in the maintenance of water balance in freshwater protozoa?
plasma membrane. it controls the water movement through osmosis.
Are Euglena helpful or harmful?
they are both harmful and helpful. when a euglenoid attracts to a substance, it helps to break it down as a saprophyte. however, sometimes the process does not work and the euglena eats the digestive enzymes so it lets out pollutants into the air.
How do chlamydomonas reproduce?
Chlamydomonas reproduce through a process called binary fission, splitting into two daughter cells. They can also reproduce sexually through the fusion of gametes, which results in the formation of a zygote that undergoes meiosis to produce new genetically diverse individuals.
Where does a plasmodium parasite live?
Mainly in mosquitos, if it lives in you, chances are you got maleria...
What structures do the amoeba paramecium and euglena all have in common?
Amoeba, paramecium, and euglena are all single-celled organisms belonging to the protist kingdom. All three have a cell membrane that surrounds the cell, a nucleus that houses the genetic material, and cilia or flagella for movement.
Plasmodium is not a bacteria to be classified whether gram negative or gram positive. It is a genus of parasitic protists. Infection by these organisms is known as malaria.
