The lipid components of cellular membranes often include phospholipids and cholesterol. Phospholipids is made up of glycerol, fatty acids, phosphate and organic derivatives such phospho inositol and choline. Cholesterol is the component of the membrane lipid which determine the fluidity of the memebrane; it also participates in membrane singalling system.

Answer from: mandy9386

The lipid components of the cellular membranes mainly include phospholipids, glycolipids, phosphoglycerides, fatty acid, cholesterol, and sphingolipids.

Further Explanation:

The bilayer is a structure through which the cell membrane maintains the cytoplasm inside the cell and extracellular fluid around the cell. Phospholipids are the basic foundation of the structure of the plasma membrane. In the plasma membrane, the phospholipids are present in the bilayer. The hydrophilic portion is an aqueous surrounding of the cytoplasm. The hydrophobic tail and extracellular fluid are pack inside and can easily be protected from the aqueous environment of the membrane.

Cholesterol is a kind of hydrophobic molecule that is mainly there in the hydrophobic tails of the phospholipid bilayer. They are present in the core of a membrane. Fatty acids are mainly joined to glycerol and make triacylglycerides, diacylglycerides, and monoacylglycosides. Sphingolipids and Glycolipids are also present in the membrane. Sphingolipids have sphingosine instead of glycerol. They both play a significant part in the fluidity of the membrane.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
