Answer 1

Chlorophyll is a bipolar macromolecule. The head part of this is made up of porphyrin ring and the tail is made up of phytol chain. 

• The top part is formed by four pyrrole molecules arranged in a cycle and form the porphyrin ring.
• In the centre of this ring is found magnesium atom.
• On the 7th carbon of fourth pyrrole ring, is attached a phytol chain which forms the phytol tail.
• The head part of chlorophyll is hydrophilic and the tail part is hydrophobic.
