If a small droplet of ordinary fat molecules is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipids is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have .

Option 1, a charged end and a noncharged end

Complete question

If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have

Solution

The structure of phospholipids consists of the following groups and molecules –  

a)A glycerol molecule  

b)Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature

c)Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.  

When the phospholipids are placed in  water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.

Hence, option 1 is correct
