WebThe cytoplasm. The cytoplasm refers to the entire region of a cell between the plasma membrane and the nuclear envelope. It is composed of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals (see figure below).Even though the cytoplasm consists of 70 to 80 percent water, it nevertheless has a semisolid consistency. WebA cell’s plasma membrane defines the boundary of the cell and determines the nature of its contact with the environment. Cells exclude some substances, take in others, and excrete still others, all in controlled quantities. Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in ...

Water is in fact an active structural component of the cell membrane. … Web• The cell membrane has a fluid consistency due to being made up of large part of phospholipids, and because of this, proteins move freely across its surface. • The multitude of different proteins and lipids in the cell membrane give it the look of a mosaic. • Phospholipids are the main component of the cell membrane.
WebKey points: All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles. Each organelle carries out a specific function in the cell.
