Solution

The correct option is C Statement 1 is correct and statement 2 is incorrect
Bacterial plasma membrane or plasmalemma has a structure similar to that of a typical membrane. It is made of a phospholipid bilayer with proteins of various types (extrinsic, integral, transmembrane). Archaebacteria are a group of most promitive prokaryotes which are able to survive in extremely hostile conditions. Their cell membranes are different from eubacteria and are characterised by the presence of a monolayer of branched chain lipids.
So, the correct answer is option C.
