What are the difference between the phosphate part and fatty acid part of phospholipids?

The phosphate head of a phosopholipid is hydrophilic, meaning it loves water, whereas the fatty acid tail is hydrophobic meaning it does not like water. in a cell membrane, the phospholipids are arranged in 2 rows so that the tails are in the centre and thererfore do not come into contact with the water inside or around the cell. in contrast, the phosphate heads are on the outside and so are in contact with water which is good as they are hydrophilic.
