and the parts that stick out are hydrophilic (Figure 2). At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane ...

There’s the membrane-bound nucleus ... the endomembrane system—the whole hodgepodge of parts found inside complex cells today—could have evolved soon after the alphaproteobacterium took ...

Lipid membranes, which form the outer layer of cells, can be engineered to influence cellular functions. For example, ...

Thin parts of the cell membranes of neurons turn ... "We're trying to understand how components of the cell membrane and the physical and chemical properties of the lipid membrane would influence ...

Like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from ...

Most tumors are sheathed in a protective "basement" membrane—a thin, pliable film that holds cancer cells in place as they grow and divide. Before spreading to other parts of the body ...

And then you'll have a model plant cell with all of its parts. A cell wall, which keeps everything together, cell membrane, which surrounds the cytoplasm, vacuole, the space within the cytoplasm ...
