Homework Answers
Ans - phospholipid bilayer is made up of phospholipid along with protein embedded in it.
With help of structure like this, the fluidity is maintained so that membrane is not rigid and allow transport of substances through it.
Protein in the membrane help in transport of hydrophobic polar molecules through it, which is very necessary for survival.
It has receptors over its surface which help in detecting signals from outer environment and thus changing its composition according.
Like bacteria living in extreme cold conditions has more chloestroch and double bonded hydrocarbon so that membrane doesn't get freeze. Like this it helps the organisim to invade in different area and help them to adapt and evolve.
