What is cytostome and its function?
A cytostome (from cyto-, cell and stome-, mouth) or cell mouth is a part of a cell specialized for phagocytosis, usually in the form of a microtubule-supported funnel or groove. Food is directed into the cytostome, and sealed into vacuoles.
What is cytostome and Cytopyge?
cy·to·stome (sī’tō-stōm), The cell “mouth” of certain complex protozoa, usually with a short gullet or cytopharynx leading food into the organism, where it is collected into food vacuoles, then circulated inside the body, eventually to be excreted through the cytopyge. [cyto- + G. stoma, mouth]
What is cytostome made of?
The cytostome is a plasma membrane invagination coupled to a few special microtubules that penetrate the cell almost to the nucleus. The opening of this complex has a diameter of up to 0.3 μm.
What is difference between cytostome and cytopharynx?
The cytostome–cytopharynx complex consists of an opening at the plasma membrane surface, close to the flagellar pocket, called the ‘cytostome’, followed by a deep membrane invagination, called the ‘cytopharynx’.
What is cytostome in microbiology?
cytostome (plural cytostomes) (microbiology) A cellular organelle found only in certain protozoa; it is specialized for phagocytosis, and usually has the form of a microtubule-supported funnel or groove.
What is the role of Cytopyge?
Cytopyge is a fixed point for waste discharge in the body of a protozoan, especially a ciliate.
What is the function of Cytopharynx?
The cytopharynx is a tube-like passageway in certain protozoans, such as ciliates and flagellates. It serves as a gullet by which food passes through. It is non-ciliated and of differing lengths depending on the species. It leads from the cytostome, which serves as the mouth.
What do you mean by Cytopyge?
Definition of cytopyge : the point especially if permanently identifiable at which waste is discharged from the protozoan body.
What do you mean by cytopyge?
Where is cytopyge found?
Paramecium
Cytopyge is found in the ”Paramecium”. Amoeba: The waste material of amoeba is removed from the body through the contractile vacuole.
What is Cytopharynx example?
noun, plural: cytopharynxes or cytopharynges. The tube-like passageway in certain protozoans through which the ingested food material passes through. Supplement. The cytopharynx is a tube-like passageway in certain protozoans, such as ciliates and flagellates. It serves as a gullet by which food passes through.
What is the function of Cytopyge?
Where is Cytopyge found?
What is Cytopyge in biology?
What does Cytopharynx mean?
Medical Definition of cytopharynx : a channel leading from the surface into the protoplasm of some unicellular organisms and functioning in ciliates as a gullet.
What is the function of cytopyge?
What is the difference between gullet and oesophagus?
The oesophagus (gullet) is part of the digestive system, which is sometimes called the gastro-intestinal tract (GI tract). The oesophagus is a muscular tube. It connects your mouth to your stomach.
Is the gullet the throat?
This shows grade level based on the word’s complexity. the esophagus. the throat or pharynx.
Where is the cytostome located in a cell?
The cytostome is located on the anterior end of the cell close to a structure known as the flagellar pocket. The flagellar pocket is also an invagination in the cell and also serves as a site of endocytosis. The opening of the cytostome is approximately level with the opening of the flagellar pocket.
What is the function of the cytostome in phagocytosis?
A cytostome (from cyto-, cell and stome-, mouth) or cell mouth is a part of a cell specialized for phagocytosis, usually in the form of a microtubule-supported funnel or groove. Food is directed into the cytostome, and sealed into vacuoles.
What is the function of the cytostome and microtubules?
The cytostome is associated with microtubules that function in maintaining its form. One set of microtubules is arranged in a triplet formation and is located directly beneath the cytostome membrane. A second set of microtubules is positioned directly beneath the flagella r pocket membrane and forms a quartet.
How does the cytostome import macromolecules?
In these instances, the cytostome imports macromolecules by directly forming vesicles that are imported into the interior of the cell. The cytostome is associated with microtubules that function in maintaining its form. One set of microtubules is arranged in a triplet formation and is located directly beneath the cytostome membrane.
