Answer:
The correct answer is - option A.
Explanation:
Among all of the given options the best character of the bacterial cell is the size of the cell which ranges in between 0.5 to 2 microns. The best evidence for the presence of bacterial cell is the smaller size of the cells.
Rest of the characters provided in the options does not matches with the characteristics of bacterial cells and not related to the bacteria.
Thus, the correct answer is option A.
The correct option is (A). Are found in Plasma membrane
Phospholipids are the major constituent of the plasma membrane.
<h3>
What are phospholipids' primary purposes?</h3>
- The primary component of the plasma membrane is phospholipids. They are made up of fatty acid chains joined to a glycerol or other similar backbone, just like fats.
- The glycerol backbone's third carbon is bonded to a phosphate group, hence there are only two fatty acids connected as opposed to three.
- An alcohol is added to the phosphate group to change it. Both hydrophilic and hydrophobic areas can be found in phospholipids. While the phosphate is hydrophilic and interacts with water, the fatty acid chains are hydrophobic and keep themselves away from it.
- A membrane with a bilayer of phospholipids surrounds each cell. The phosphate group can face either the outside environment or the inside of the cell, both of which are watery, as opposed to the fatty acids of phospholipids, which face within, away from water.
