The cytoplasm can be easily observed by staining the cell and examining it under a microscope. The main components of the cytoplasm are cytosol, organelles, and cytoplasmic inclusions.\u00a0Below in Figure 3 is a well-labeled diagram of the cytoplasm structure<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cytosol<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The\u00a0<strong>cytosol<\/strong>\u00a0is the part of the cytoplasm that is the liquid-like portion. It is mostly made up of water, dissolved minerals, and cytoskeleton filaments. It, however, does not contain any organelles but holds them within the cell as part of the entire cytoplasm.\u00a0 It consists of water, organic molecules, and dissolved ions. The highest percentage of cytosol component is water, i.e. about 70%. The typical ions in the mammalian cytosol are potassium, sodium, chloride, bicarbonate, amino acids in proteins, magnesium, and calcium. The cytosol serves as the site where many chemical reactions take place. In prokaryotes, it is where most metabolic reactions take place (others occur in the cell membrane). In eukaryotes, it is where the organelles and other cytoplasmic structures are suspended. Since the cytosol contains dissolved ions, it plays a role in\u00a0osmoregulation\u00a0and cell signaling. It is also involved in generating\u00a0action potentials\u00a0in cells, such as endocrine,\u00a0nerve, and\u00a0muscle cells.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Organelles<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Organelles<\/strong>\u00a0are the membrane-bond, specialized structures within cells that carry out specific tasks for the cell. The term \u201c<em>organelles<\/em>\u201d is based on the organs, as the organs in animals and humans work similarly in carrying out a specific task for the body. See Figure 3 for the various organelles found in a plant cell and an animal cell.\u00a0In eukaryotic cells, the\u00a0nucleus, for instance, is the organelle that contains the genetic material, and therefore it controls cellular activities such as metabolism, growth, and\u00a0reproduction\u00a0by regulating gene expression.\u00a0Chloroplasts\u00a0are plastids containing green pigments essential for\u00a0photosynthesis.\u00a0Mitochondria\u00a0are the organelles that synthesize energy for multifarious metabolic processes. The\u00a0endoplasmic reticulum\u00a0occurs as an interconnected network of flattened sacs or tubules involved in lipid synthesis, carbohydrate metabolism, drug detoxification, and attachment of receptors on cell membrane proteins. It is also involved in intracellular transport, such as the transport of the products (of the rough endoplasmic reticulum) to other cell parts like the Golgi apparatus.\u00a0Golgi apparatus\u00a0is made up of membrane-bound stacks. It is involved in glycosylation, packaging of molecules for secretion, transporting of lipids within the cell, and giving rise to lysosomes. Other cytoplasmic structures found in the cytoplasm are\u00a0vacuoles\u00a0and\u00a0ribosomes. Ribosomes, the site of protein synthesis, are comprised of protein and\u00a0RNA. Some ribosomes are unbound whereas the others are attached to the endoplasmic reticulum.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cytoplasmic Inclusions<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cytoplasmic inclusions<\/strong>\u00a0are part of the cytosol but are not membrane-bound so they are not considered organelles. Instead, they are suspended in the cytosol as small, insoluble particles. Cytoplasmic inclusions depend on the type of cell they are in. For instance, an animal cell would neither have nor need\u00a0starch,\u00a0<em>the\u00a0glycogen\u00a0of <\/em>Polyhydroxybutyrate <em>(PHB)<\/em>, because these are energy storage units that are needed by plant cells after they photosynthesize. On the other hand, there are cytoplasmic inclusions called\u00a0<em><strong>lipid droplets<\/strong><\/em>. These are used by both plant and animals cells to store\u00a0lipids\u00a0like\u00a0fatty acids. Lipid droplets are made of both lipids and proteins so that they don\u2019t dissolve into the cytosol.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Cytosol Organelles Cytoplasmic Inclusions<\/p>\n","protected":false},"author":1,"featured_media":885,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[233],"tags":[],"class_list":["post-889","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cytoplasm"],"jetpack_featured_media_url":"https:\/\/workhouse.sweetdishy.com\/wp-content\/uploads\/2024\/04\/cytoplasm.png","_links":{"self":[{"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/posts\/889","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/comments?post=889"}],"version-history":[{"count":1,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/posts\/889\/revisions"}],"predecessor-version":[{"id":890,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/posts\/889\/revisions\/890"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/media\/885"}],"wp:attachment":[{"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/media?parent=889"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/categories?post=889"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/workhouse.sweetdishy.com\/index.php\/wp-json\/wp\/v2\/tags?post=889"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
