What are cytoplasmic organelles?
Are parts of the cell that carry on many of the functions needed to keep the cell alive.
In extra chromosomal inheritance the following three examples are discussed 1.Maternal effects depending indirectly on nuclear gene and involving no known cytoplasmic hereditary units. 2. cytoplasmic inheritance involving dispensable and infective hereditary particles in cytoplasm which may or may not depend on nuclear genes 3. Cytoplasmic inheritance involving essential organelles like chloroplasts and mitichondria.
Eukaryotes have a membrane-bound nucleus and membrane-bound organelles. Organism whose cells have (1) chromosomes with nucleosomal structure and separated from the cytoplasm by a two-membrane nuclear envelope, and (2) compartmentalization of functions in distinct cytoplasmic organelles. Contrast prokaryotes (bacteria and cyanobacteria).
Cytosol is the closest name. According to the American Heritage Dictionary: * Cytoplasm-The protoplasm outside the nucleus of a cell. * Cytosol-The fluid component of cytoplasm, excluding organelles and the insoluble, usually suspended, cytoplasmic components. So cytoplasm is the fluid in the cell WITHOUT the nucleus, but INCLUDING the other organelles, while cytosol is the fluid in the cell WITHOUT the nucleus, and WITHOUT the other organelles
Prokaryotic cells do not contain organelles in the same manner as Eukaryotic cells. They have a number of various structures but these are only particles that float around in the cytoplasm. Some water bacteria contain vacuoles containing air but don't. Often the cytoplasmic membrane has cysts where the membrane bubbles away and forms cysts but the reason is obscure.
Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's. When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their…
What Phase of the cell cycle in which the cell makes molecules and organelles needed for the new cell?
Microtubules are located in three locations in the cell. They are: 1. Cytoplasmic microtubles which, as the name suggests is located in the cytoplasm. 2. Axonemal microtubules that are located in cilia and flagella 3. Basal bodies, which are structures located at the base of a cilium and contains microtubules. Generally, microtubules originate from cytoplasmic organelles called centrioles. The region from which microtubules originate is called the microtubule organizing center.
Basically, cytoplasm is the fluid, where the organelles remain suspended. So, it fills up the cell, especially the spaces not occupied by any organelle. The constituent parts of cytoplasm are cytosol, organelles and cytoplasmic inclusions. So, it fills up any empty spaces not occupied by an organelle. Thus, its fluid-like structure helps cytoplasm do its vocation.
