Protozoa

Paramecium feed on microorganisms like bacteria, algae, and yeasts. In order to gather its food the paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. The food goes through the cell mouth into the gullet, which is like the stomach. When there is enough food in it so that it has reached a certain size it breaks away and forms a food vacuole. The food vacuole travels through the cell, through the back end first. As it moves along enzymes from the cytoplasm enter the vacuole and digest it. The digested food then goes into the cytoplasm and the vacuole gets smaller and smaller. When the vacuole reaches the anal pore the remaining undigested waste is removed.

Amoeba is a microphagous feeder, which means that it feeds upon small aquatic organisms like bacteria, flagellates, ciliates and minute food particles.

When a hungry Amoeba approaches to some food particle, it produces out its pseudopodia in the form of food cup which engulf the food particle by turning into food vacuole. the food also contain some water. this complete ingestion. the next step is digestion which is faciliated by the lysosomes. A few lysosomes surround the food vacuole and get fused with the membrane to discharge their enzymatic contents(proteases, amylases and lipases)into it. Hence the digestion is intacellular. At this stage the vacuole becomes a digestive vacuole. It decrease in size as the water is withdrawn and its content first become acidic(pH 5.6) and then alkaline(pH 7.3). When the digestion is completed, the digestive vacuole membrane is drawn into numerous fine canals. the soluble food particles are passed into the canals and finally into the surrounding cytoplasm by micropinocytosis. the digested food, water and minerals are absorbed(absorption) into the cytoplasm and circulate in it, through cyclosis where the food is assimilated into new protoplasm or is oxidized to librate energy. the undigested food is egested by exocytosis at the rear end.

1. Amoeba: A unicellular organism that moves using pseudopods and feeds mainly on bacteria and algae.
2. Paramecium: A ciliated protozoan that feeds on bacteria and other small organisms.
3. Trypanosoma: A parasitic protozoan that causes diseases such as sleeping sickness and Chagas disease.
4. Plasmodium: The protozoan responsible for causing malaria in humans.
5. Giardia: A flagellated protozoan that can cause gastrointestinal illness in humans and animals.

Euglena obtain nutrients through photosynthesis, where they use sunlight to produce sugars. They also feed on organic matter and other organisms through phagocytosis, a process where they engulf and digest their food.

Pseudopodia are temporary protrusions of the cell membrane in amoeboid cells like amoeba. These structures are used for movement and to engulf food particles through phagocytosis. Pseudopodia are formed by the cytoskeleton and are constantly changing shape as the cell moves.

yes euglena is a living thing i recently did a project on it myself and found this out..... it is nor plant or animal its belongs to a group called patista or sumthin like dat. it can feed its self like a plant but moves like a animal. i hope this has helped you from ella xxxx

Yes, both amoeba and euglena are single-celled organisms that can survive independently without each other. They obtain their nutrients and energy from their surroundings, so they do not require a symbiotic relationship to survive.

Paramecium look like little peanuts or slippers, with one end coming to a point. They are very tiny, (about 0.02 in) and you will need to look under a microscope to see one, and it is very difficult as they move quickly.

Parameciums reproduce asexually by binary fission, where the cell divides into two equal parts. They can also undergo sexual reproduction through a process called conjugation, where genetic material is exchanged between two organisms.

A paramecium typically has thousands of cells, which make up its single-celled organism structure. The cells in a paramecium are specialized to perform various functions, such as movement, feeding, and reproduction.

Multicellular Volvox has increased size and complexity compared to unicellular Chlamydomonas, allowing for more diverse functions to be carried out by specialized cells. Volvox also benefits from cooperation among cells, enabling division of labor and enhanced reproductive capabilities through the production of both somatic and reproductive cells. Additionally, the multicellularity of Volvox provides protection and support for individual cells, leading to increased survival and ecological success.

Amoebas generally feed on microscopic organisms like bacteria, algae, and other small particles. They engulf these particles through a process called phagocytosis, where they surround and ingest the food particles using their pseudopods. The diet of an amoeba is primarily based on what is available in their environment.

The general body shape of a euglena is elongated and spindle-like, with a flexible outer membrane called a pellicle that allows the organism to change its shape. Euglenas are unicellular organisms that can be either elongated or slightly flattened, depending on the species and environmental conditions.

There are two main types of Euglena: autotrophic Euglena that can photosynthesize and heterotrophic Euglena that must ingest food particles to survive. Autotrophic Euglena have chloroplasts and can produce their own food through photosynthesis, while heterotrophic Euglena do not have chloroplasts and rely on absorbing nutrients from their environment.

They are both cells and are both living.

Some common types of protozoa include amoebas, paramecia, flagellates, and ciliates. These single-celled organisms are found in various aquatic and terrestrial environments and play essential roles in nutrient cycling and microbial ecosystems.

Flagellates, ciliates, and amoebas are all types of protists that belong to the kingdom Protista. They are single-celled organisms that can move and feed in various ways. Flagellates have flagella for movement, ciliates have cilia, and amoebas move through pseudopods.

Parameciums move by using hair-like structures called cilia that cover their outer surface. These cilia beat in a coordinated manner, propelling the paramecium through water in a spiraling fashion. This movement helps them to find food and avoid predators.

When a protozoan gains its food from the environment, it is considered a heterotroph. This means that it obtains nutrients by consuming other organisms or organic matter from its surroundings.

Paramecium need to regulate their internal water content to prevent bursting due to excessive water intake through osmosis. They remove water by contracting their contractile vacuole, which expels excess water from the cell to maintain internal balance, ensuring their survival in various environments.

Amoebas are protists and therefore unicellular eukaryotic organisms. This means that they contain a nucleus. The DNA of ANY eukaryotic organism is found in the nucleus.

Phylum Amoebozoa.

Some unicellular organisms with ameboid forms are also commonly called "amoeba", but they do not belong always to phylum Amoebozoa. Amoeba is a genus, however, all species of phylum Amoebozoa are currently called amoebae.

Paramecium moves through the water by beating hair-like structures called cilia in a coordinated manner. These cilia create a spiraling motion that propels the paramecium forward or backward. This movement allows the paramecium to navigate its environment in search of food and avoid predators.

Paramecium are typically found in freshwater environments such as ponds, lakes, and slow-moving streams. They are also commonly found in microbiology laboratories where they are studied as model organisms.
