Lipids have hydrophilic (water loving) heads, and hydrophobic (tails). Therefore, the tails face one another while the heads face out to the water. And if particles must pass through the cellular membrane that are hydrophilic they must go through protein channels within the cell membrane.

I was stuck on this in Biology class, too. Here's what I think to be the answer:
The lipids have hydrophilic, which means water loving, heads, and hydrophobic, which means water hating, tails. So, all the heads face one way while all the tails face the other. If particles pass through the lipid bilayer, which is basically a bunch of those hydrophilic heads and hydrophobic tails, they must go through protein channels within the lipid bilayer. This is similar to a cell membrane, because cell membranes let certain things into the cell, but don't let other things.
Lipids do give cells membranes a flexible structure that forms a strong barrier between the cell and the cell surroundings. Hence, the lipid surrounds the structure which then forms the shape of the cell.
The GA in lipids lends some rigidity to the cell membrane. It helps with shape and aids in structure.
Lipids are created in the smooth endoplasmic reticulum of a cell. Many are used in the cell membrane, particularly phospholipids, whose double layer creates the basic structure of the membrane.
Lipids, in the form of the bi-lipid layer.
the lipids has the fatty acids and the glyceral in the structure and the proteins has the amino acids in their structure the carbohydrades has the different sugars with different carbon skeletan structure and the nucleic acids have the different nucleotide sequence which makes it easy to identity a molecule
yes membrane made up of lipids,proteins, nucleic acid,

plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.

it may be the ER membrane
they are fuelreserves of our body and forms as constitutes of membrane structure and regulate membrane permeability.
i think it may be fatty acids
proteins carbohydrates lipids and nucleic acids
energy membrane structure insulation source of glycerol
cell membrane

why are fatty acids important to the cell membrane
