How are phospholipids arranged in cells?

Answer 1

In a dual layer; the tails are facing towards each other, so there is a layer of phospholipid heads on the outer surface of the cell membrane, & another layer of heads on the inner surface of the membrane.

Answer 2

Their hydrophyllic heads face out into solution and their hydrophobic tails are excluded from hydrogen bonding among water molecules so they are forced to face away from the solution. Thus we get the bilayer that forms cell membranes; tails facing each other inside and heads facing outwards.

Sort of like that.

Answer 3

Two layers of phospholipids are arranged as a bilayer that forms the basis of cell membrane structure. One layer has its hydrophilic heads neighbouring the surroundings whereas the other has its hydrophilic heads neighbouring the cytoplasm. The hydropholic fatty acid tails of both layers of phospholipid point towards the centre.

Answer 4

They are lipids containing phosphate groups.They consist of hydrophobic tail and hydrophilic head.
