Although the inner leaflet of the gram-negative outer membrane is composed mainly of phospholipids, the outer leaflet of the outer membrane contains lipopolysaccharides.
Phospholipids are the most abundant component of the plasma membrane. The structure of phospholipids is composed of a backbone of glycerol containing two fatty acid chains attached to two hydroxyl groups and one phosphate group attached to the third hydroxyl group.
Lipopolysaccharides, also abbreviated as LPS, are the major component of bacterial cell wall. The role of LPS is to provide structural integrity and high permeability to the bacteria. LPS is a pyrogen and can be toxic to human body.

<u>Answer:</u> Both require a vacuum.
<em>The common feature of scanning electron microscope and transmission electron microscope is that they both require vacuum.
</em>
<u>Explanation:</u>
Electron microscope has <em>various advantages over light microscope</em> due to their better magnification and resolution. The transmission electron microscope and scanning electron microscope use electrons for functioning. Thus they require vacuum for their operation since the electrons will be <em>lost in the absence of vacuum.
</em>
Thus it is impossible to examine living cells under an <em>electron microscope.</em> The nature of the images formed by these microscopes is different. Transmission electron microscopes produce <em>2 D images while scanning electron microscopes produce 3D images.
