Function or cytopharynx in Paramecium?

User Avatar

Asked by Wiki User

The cytopharynx in Paramecium is a tubular structure used for feeding. It helps in capturing and engulfing food particles, such as bacteria and algae, through a process called phagocytosis. Once food particles are ingested into the cytopharynx, they are enclosed in a food vacuole for digestion.

What is the source of the water discharged by the two large vacuoles of a paramecium?

User Avatar

Asked by Olive4ever

The water discharged by the large vacuoles of a paramecium comes from the surrounding environment. The vacuoles regulate water balance within the cell by taking in excess water through the process of osmosis and then expelling it to prevent the cell from bursting.

How is amoeba able to move?

User Avatar

Asked by Wiki User

Amoebas move by extending and retracting their pseudopods, which are temporary projections of the cell membrane filled with cytoplasm. By changing the shape of these pseudopods, amoebas are able to propel themselves forward in a process known as amoeboid movement. This movement allows them to search for food and navigate their environment.

What organelles are found in an amoeba?

User Avatar

Asked by Wiki User

An amoeba contains several organelles, including a nucleus, mitochondria for energy production, golgi apparatus for packaging and transporting proteins, and vacuoles for storing nutrients and expelling waste. Some amoebas also have specialized organelles like contractile vacuoles for osmoregulation.

How is the zoospore of the unicellular green alga Chlamydomonas formed?

User Avatar

Asked by Wiki User

The zoospores of Chlamydomonas are formed through a process known as zoosporogenesis. It involves the transformation of a motile, flagellated cell called a zoospore mother cell into mature zoospores. This process includes the growth of flagella and chloroplasts within the mother cell before division to form new zoospores.

Chlamydomonas move by their flagella?

User Avatar

Asked by Wiki User

Yes, Chlamydomonas move by beating their two flagella, which are whip-like structures attached to their cell body. The movement of the flagella allows them to swim through their aquatic environment in search of light and nutrients.

Can euglena cause disease?

User Avatar

Asked by Wiki User

Euglena are not known to cause disease in humans. They are single-celled organisms that are found in freshwater environments and play a role in the ecosystem as primary producers. While they can be a part of the food chain and have been studied for their photosynthetic abilities, they are not typically associated with causing diseases in humans.

Where does digestion happen in the ameba and paramecium?

User Avatar

Asked by Wiki User

In Amoeba, digestion occurs in the food vacuoles, where enzymes break down food particles into simpler substances that can be absorbed by the cell.

In Paramecium, digestion happens in food vacuoles as well. Food particles are engulfed by cilia, forming a food vacuole that fuses with lysosomes to digest the food using enzymes.

Is the movement of chlamydomonas smooth or jerky?

User Avatar

Asked by Wiki User

The movement of Chlamydomonas is smooth. It moves using two whip-like structures called flagella, which allow it to navigate through its aquatic environment in a relatively controlled manner.

What type of locomotion do protozoa have?

User Avatar

Asked by Wiki User

Protozoa exhibit various types of locomotion, including flagellar movement (whipping motion with flagella), ciliary movement (using hair-like cilia for propulsion), and amoeboid movement (crawling using pseudopods or cell extensions). The specific type of locomotion employed by a protozoan species depends on its structural adaptations and environmental conditions.

What does paramecium possess that counteracts the effect of osmosis?

User Avatar

Asked by Wiki User

Paramecium possess contractile vacuoles that help regulate water content within the cell and prevent it from bursting due to excess water entering through osmosis. These vacuoles actively pump out water to maintain a stable internal environment.

When a chemical is added to a microscope slide with a live paramecium the paramecium moves away from the chemical This movement is an example of?

User Avatar

Asked by Wiki User

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.

Is genital warts a protozoa?

User Avatar

Asked by Wiki User

Genital warts are not caused by protozoa. Genital warts are caused by the human papillomavirus (HPV), which is a virus, not a protozoa.

What is the economic importance of euglena?

User Avatar

Asked by Wiki User

Euglena is a micro organism, so it economic importance is contradicting because it is sometimes heterotrophy (like animals) and autrotrophy (like plant). It contain chlorophyll for food production to plants in water and it has some carotenoid pigments thats produces sugers by photosynthesis and in turn produces oxygen

Is Plasmodium a heterotroph?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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 is a protozoan with two nuclei that moves using cila?

User Avatar

Asked by Wiki User

Paramecium is a protozoan with two nuclei (macronucleus and micronucleus) and moves using cilia. Cilia are hair-like structures that beat back and forth to propel the organism through its aquatic environment.

How does protozoa enter the body?

Asked by Wiki User

The disadvantages of euglena are mostly related to its structure and the fact that there is a debate that never ends on whether it is a plant or animal. The lack of routine genetic analysis is the main disadvantage.

Is Volvox a unicellular organism or multicellular?

User Avatar

Asked by Wiki User

Volvoxis the most developed in a series of genera that form spherical colonies. Each mature Volvoxcolony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein. The cells swim in a coordinated fashion, with distinct anterior and posterior poles. The cells have eyespots, more developed near the anterior, which enable the colony to swim towards light. The individual algae in some species are interconnected by thin strands of cytoplasm, called protoplasmates.[4] They are known to demonstrate some individuality and working for the good of their colony, acting like one multicellular organism. The flagellates on its outside resemble Euglena.

What characteristic do volvox and euglena share?

User Avatar

Asked by Wiki User

Both Volvox and Euglena are single-celled organisms that possess a flagellum for movement. Additionally, both have a primitive eyespot that allows them to detect light for photosynthesis or movement towards light.

The primary difference between bacteria and all higher organisms such as protozoa is bacteria do not have a membrane-bound?

User Avatar

Asked by Wiki User

The primary difference is that bacteria lack a membrane-bound nucleus, while higher organisms such as protozoa have a nucleus enclosed in a membrane. This means that bacterial DNA is usually found in the cytoplasm, while eukaryotic organisms have their DNA enclosed in the nucleus.
