- In cell biology, the cytoplasm is a highly viscous (gel-like) substance enclosed within the cell membrane. It's composed of water (about 85 percent), proteins (10 to 15%), lipids (2 to 4%), nucleic acids, inorganic salts and polysaccharides in smaller amounts.

Cytoplasm refers to the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the nucleus. Eukaryotes have elaborate mechanisms for maintaining...
The cytoplasm is unusual because it is unlike any other fluid found in the physical world. Liquids that are studied to understand diffusion usually contain a few solutes in an aqueous environment. However, the cytoplasm is a complex and crowded system containing a wide range of particles – from ions and small molecules, to proteins as well as giant...
The cytoplasm is the site for most of the enzymatic reactions and metabolic activity of the cell. Cellular respiration begins in the cytoplasm with anaerobic respiration or glycolysis. This reaction provides the intermediates that are used by the mitochondria to generate ATP. In addition, the translation of mRNA into proteins on ribosomes also occu...
Movement within the cytoplasm also occurs in bulk, through the directed movement of cytosol around the nucleus or vacuole. This is particularly important in large single celled organisms such as some species of green algae, which can be nearly 10 cm in length. Cytoplasmic streaming is also important for positioning chloroplasts close to the plasma ...
The cytoplasm plays hosts to two organelles that contain their own genomes – the chloroplast and mitochondria. These organelles are inherited directly from the mother through the oocyte and therefore constitute genes that are inherited outside the nucleus. These organelles replicate independent of the nucleus and respond to the needs of the cell. C...
Chemotaxis– Movement of a cell in response to a chemical signal.Intermediate Filaments– Cytoskeletal components formed by a family of proteins sharing structural and functional features larger than actin fibers and smaller than microtubules.Kinesin– A group of motor proteins that can travel along a microtubule and are important for the movement of cellular components, especially during cell division.Syncytium– A multinucleated cell formed by the fusion of the plasma membrane of multiple cells. Syncytia can also be formed through the interconnections between cells containing specialized gap jun...1. Which of these biomolecules are NOT present as cytoplasmic inclusions? A. Lipids B.

Apr 12, 2019 · The cytoplasm is the gel-like material that constitutes most of the interior of biological cells. In prokaryotes, it is essentially everything inside the cell membrane; in eukaryotes, it holds everything inside the cell membrane, in particular the organelles. Cytosol is the matrix component.
Cytoplasm - The cytoplasm is the jelly-like substance inside a cell where the chemical reactions of the cell take place. Nucleus - The nucleus contains DNA, which stores information that controls the activities of the cell.
