pseudopodium, temporary or semipermanent extension of the cytoplasm, used in locomotion and feeding by all sarcodine protozoans (i.e., those with pseudopodia; see sarcodine) and some flagellate protozoans.

2022年4月8日 · A pseudopodium (plural: pseudopodia) refers to the temporary projection of the cytoplasm of a eukaryotic cell. Pseudopodia are arm-like projections filled with cytoplasm. The projecting cytoplasm, in turn, primarily contains cytoskeleton, such as actin filaments, intermediate filaments, and microtubules.

2017年4月28日 · Pseudopodium – A single temporary projection from the cell of white blood cells and protozoans that is used for locomotion and feeding. Phagocytosis – The ingestion of materials like bacteria, virus and broken cells by amoeboids and phagocytes such as the white blood cells.

Pseudopodial locomotion is a type of cellular movement used by certain eukaryotes, particularly slime molds and certain types of protozoans, such as amoebas. In multicellular organisms, some motile cell types, such as white blood cells and some kinds of tumour cells, also use a form of pseudopodial locomotion.

2024年4月8日 · In summary, pseudopods are multifaceted cellular structures that serve critical roles in cellular locomotion and nutrient acquisition. Their formation is a highly regulated event, contingent on a myriad of intracellular activities and environmental cues.

Also known as pseudopodia (singular noun: pseudopodium), pseudopods are temporary extensions of the cytoplasm (also referred to as false feet) used for locomotion and feeling. They can be found in all sarcodines as well as a number of flagellate protozoa that either exist as parasites or as free living organisms.

2024年7月9日 · Explore how pseudopodia facilitate cell movement and immune defense, highlighting their types and roles in various organisms. Cells play a fundamental role in biological systems, and understanding their mechanisms of movement and defense can shed light on many vital processes.

The meaning of PSEUDOPODIUM is a temporary protrusion or retractile process of the cytoplasm of a cell (such as an amoeba or a white blood cell) that functions especially as an organ of locomotion or in taking up food or other particulate matter.

These findings establish CAS/Crk as an essential scaffold for Rac1-mediated pseudopodia growth and retraction, and illustrate spatio-temporal segregation of cytoskeletal signals during cell polarization. Keywords: cell migration; chemotaxis; signal …

These two molecules function in the amoebae in a manner similar to their roles in the contraction of vertebrate muscle. Activated by ATP-derived energy and certain cations, such as calcium and magnesium, actin and myosin become intimately associated …

pseudopodium (pl. psuedopodia) a protoplasmic projection (a ‘false foot’) from the main body of a protozoan - especially Rhizopods such as Amoeba - and from white blood cells.

A pseudopod or pseudopodium (plural: pseudopods) (from the Greek word ψευδοποδός, ψευδός “false” + ποδός “foot”) can be used for motility or to ingest nutrients or other particles.

2023年8月22日 · Pseudopodia, from the Greek 'pseudo-' meaning 'false', and '-podia' meaning 'feet', are temporary, arm-like projections of the cytoplasm used for motion or capturing food. But why are pseudopodia essential to microorganisms? A primary reason is movement.

Pseudopodium. A transitory extension from a cell that may be extended or retracted either to effect motility or to engulf food particles. Sometimes both activities occur at the same time. A few protists have fixed body shapes from which a pseudopodium can arise only from a …

Pseudopodia (singular: pseudopodium) are temporary cytoplasmic projections or cell membrane extensions that enable cells to move and interact with their surroundings. The term “pseudopodium” originates from the Greek words “pseudes,” meaning “false,” and “podion,” meaning “little foot.”

Pseudopodia (sing: pseudopodium) are cytoplasmic projections that are found on the cell membranes of eukaryotic cells. The word pseudopodia is derived from pseudo meaning false and podia meaning feet.

2023年6月22日 · Pseudopodia are temporary projections that extend from the cell body of certain single-celled organisms. They function as versatile cellular tools, serving primarily for movement and for capturing food.

In this article we will discuss about Pseudpodia:- 1. Meaning of Pseudopodia 2. Role of Pseudopodia in Amoeboid Movement. Meaning of Pseudopodia: Amoeboid movement is a form of loco­motion characteristic of many of the sarcodine protozoa.

2023年11月21日 · Learn what is pseudopodia, how it is defined, and how it functions in protozoans for movement and feeding. Also learn about the different shapes of pseudopods. Updated: 11/21/2023. Envisioning...
