Question

Which of these structures of the phospholipid bilayer is correctly matched with its property?

(a) Phosphate head – hydrophobic

(b) Phosphate head – hydrophilic

(c) Lipid tail – hydrophilic

(d) Lipid tail – Polar

This question was addressed to me in semester exam.

I need to ask this question from Eukaryotic Cells and it’s Organelles in portion Cell : The Unit of Life of Biology – Class 11

Answer 1

Right option is (b) Phosphate head – hydrophilic

Easiest explanation: The cell membrane is a phospholipid bilayer in which the polar and hydrophilic phosphate head groups face outwards, while the non-polar and hydrophilic lipid tails face each other.
