Functional groups refers to a specific group of atoms within a molecule, which usually have characteristic features, the other molecules in the substance not withstanding. 
Two of the functional groups found in phospholipids are carboxylic acid and phosphate groups. 

Answer;

- phosphate group

- Ester functional group

- Alkene

- Alkane side chains.


Explanation;

Phospholipids are types of lipids that are major components of the cell membranes.

They consist both the hydrophillic (water loving) and hydrophobic (water hating) ends.

The major functional groups in a phospholipids are;

- the phosphate groups - PO4

- The Ester functional group- - COO-R

- Alkene side chain - -CH=CH-

- Alkane side chain - -CH-CH-
