SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter. Cells that make pseudopods are generally referred to as amoeboids. Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments. Filaments near the cell's end interact with myosin which causes contraction. The pseudopod extends itself until the actin reassembles itself into a network. It is supposed that actin polymerization is at the origin of the force propelling the cell forward. Generally several pseudopodia arise from the surface of the body (polypodial, e.g. Amoeba proteus), or a single pseudopod may form on the surface of the body (monopodial, e.g. Entamoeba histolytica). Pseudopodia are formed by microtubule and filament structures. The cell surface projects a membrane process called the lamellipodium, which is supported inside by filaments that form at the leading edge, turning into networks as they merge. Cytoplasm flows into the lamellipodium, forming the pseudopodia. The functions of pseudopodia include locomotion and the capturing of prey. Pseudopodia are critical in sensing prey that can then be engulfed; the engulfing pseudopodia are called phagocytosis pseudopodia. A common example of this sort of amoeboid cell is the human white blood cell. Human mesenchymal stem cells are a good example of a cell type which uses pseudopodia for locomotive reasons: these migratory cells are responsible for in-utero remodeling for example in the formation of the trilaminar germ disc during gastrulation. Pseudopodia do not all look like amorphous blobs; instead, they can be classified by their distinct appearances. Lobopodia are bulbous and amoebic. Filopodia are slender, thread-like, and are supported largely by microfilaments. Reticulopodia are very complex and bear individual pseudopodia that form irregular nets. Axopodia are the phagocytosis type with long, thin pseudopods supported by complex microtubule arrays enveloped with cytoplasm, and they respond rapidly to physical contact. Pseudopods can be classified into several varieties according to their appearance: 1. Lobopodia are bulbous, short, and blunt in form. They are very typical of Amoebozoa. These finger-like, tubular pseudopodia contain both ectoplasm and endoplasm. 2. Filopodia are more slender and filiform with pointed ends, consisting mainly of ectoplasm. These formations are supported by microfilaments. This is observed in Euglypha and Lecithium. 3. Reticulopodia, also known as reticulose pseudopods, are complex formations where individual pseudopods are blended together and form irregular nets. The primary function of reticulopodia, also known as myxopodia, is the ingestion of food, with locomotion a secondary function. Reticulopods are typical of Foraminifera. 4. Axopodia (also known as actinopodia) are thin pseudopods containing complex arrays of microtubules and are enveloped by cytoplasm. Axopodia are mostly responsible for phagocytosis by rapidly retracting in response to physical contacts. They are observed in Radiolaria and heliozoa. This supposedly takes a strain on the helix, for after the sensory action has occurred, it then later on dies. Principally, these pseudopodia are food collecting structures.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Endoplasm generally refers to the inner (often granulated), dense part of a cell's cytoplasm. This is opposed to the ectoplasm which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane. These two terms are mainly used to describe the cytoplasm of the amoeba, a protozoan, eukaryotic cell. The nucleus is separated from the endoplasm by the nuclear envelope. The different makeups/viscosities of the endoplasm and ectoplasm contribute to the amoeba's locomotion through the formation of a pseudopod. However, other types of cells have cytoplasm divided into endo- and ectoplasm. The endoplasm, along with its granules, contains water, nucleic acids amino acids, carbohydrates, inorganic ions, lipids, enzymes, and other molecular compounds. It is the site of most cellular processes as it houses the organelles that make up the endomembrane system, as well as those that stand alone. The endoplasm is necessary for most metabolic activities, including cell division. The endoplasm, like the cytoplasm, is far from static. It is in a constant state of flux through intracellular transport, as vesicles are shuttled between organelles and to/from the plasma membrane. Materials are regularly both degraded and synthesized within the endoplasm based on the needs of the cell and/or organism. Some components of the cytoskeleton run throughout the endoplasm though most are concentrated in the ectoplasm - towards the cells edges, closer to the plasma membrane. The endoplasm’s granules are suspended in cytosol. The term granule refers to a small particle within the endoplasm, typically the secretory vesicles. The granule is the defining characteristic of the endoplasm, as they are typically not present within the ectoplasm. These offshoots of the endomembrane system are enclosed by a phospholipid bilayer and can fuse with other organelles as well as the plasma membrane. Their membrane is only semipermeable and allows them to house substances that could be harmful to the cell if they were allowed to flow freely within the cytosol. These granules give the cell a large amount of regulation and control over the wide variety of metabolic activities that take place within the endoplasm. There are many different types, characterized by the substance that the vesicle contains. These granules/vesicles can contain enzymes, neurotransmitters, hormones, and waste. Typically the contents are destined for another cell/tissue. These vesicles act as a form of storage and release their contents when needed, often prompted by a signaling pathway. Once signaled to move, the vesicles can travel along aspects of the cytoskeleton via motor proteins to reach their final destination. The cytosol makes up the semifluid portion of the endoplasm, in which materials are suspended. It is a concentrated aqueous gel with molecules so crowded and packed together within the water base that it's behavior is more gel-like than liquid. It is water based but contains both small and large molecules, giving it density. It has several functions, including physical support of the cell, preventing collapse, as well as degrading nutrients, transport of small molecules, and containing the ribosomes responsible for protein synthesis. Cytosol contains predominantly water, but also has a complex mixture of large hydrophilic molecules, smaller molecules and proteins, and dissolved ions. The contents of the cytosol change based on the needs of the cell. Not to be confused with the cytoplasm, the cytosol is only the gel matrix of the cell which does not include many of the macromolecules essential to cellular function.

Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell. Groups of amoebae are distinguished by the appearance and internal structure of their pseudopods. Amoebozoan species typically have bulbous pseudopods, rounded at the ends and roughly tubular in cross-section (lobose). Cercozoan amoeboids, such as Euglypha and Gromia, have slender, thread-like (filose) pseudopods. Foraminiferan emit fine, branching pseudopods that merge with one another to form net-like (reticulose) structures. Some groups, such as the Radiolaria and the amoeboids loosely called Heliozoa, have stiff, needle-like, radiating actinopods supported from within by bundles of microtubules.
