What else can I help you with?
Is bilayer hydrophilic?
A bilayer is composed of two layers of phospholipid molecules, which have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails. The hydrophilic heads face outward towards the surrounding water, making the bilayer as a whole hydrophilic on the outer surfaces.
Which model did scientist develop to describe the cell membrane?
the cell is a phospholipid bilayer. this means that there are 2 layers of phospholipids with hydrophobic tails and hydrophilic heads.
Do glycolipids have hydrophilic heads?
Yes, glycolipids have hydrophilic heads. They consist of a hydrophilic carbohydrate portion attached to a hydrophobic lipid tail, making them amphipathic molecules. This structure allows them to interact with water and form the lipid bilayer in cell membranes.
What makes it possible for the plasma membrane to self assemble?
The plasma membrane is able to self-assemble due to the properties of its constituent molecules, such as phospholipids. Phospholipids have hydrophilic heads and hydrophobic tails, which drives them to form a bilayer structure when exposed to water. This spontaneous assembly is driven by the hydrophobic effect and results in the formation of a stable and selectively permeable membrane.
What structure in a cell membrane repels charged particles?
The Hydrophobic phospholipid "tails." Cell Membranes are composed of lines of hydrophilic (water loving) phospholipid heads that face outside the cell and inside the cell. On the inside of the membrane, however, are hydrophobic (water hating) phospholipid tails, which repel charged particles.

Are the heads of phospholipids hydrophilic?
Yes, the heads of phospholipids are hydrophilic.
Are heads hydrophilic in cell membranes?
Yes, heads of phospholipids in cell membranes are hydrophilic, meaning they are attracted to water.

Water-loving heads of phospholipids?
hydrophilic

Why are phospholipids arranged as they are in a bi-layer?
Membranes self assemble as a result of the hydrophobic effect. This is the tendency of nonpolar substances to aggregate in aqueous solution and exclude water molecules. This can be shown by the hydrophobic tails coming together, and the hydrophilic heads facing the outside and inside of the cell.
Do hydrophilic heads on plasma membranes attract or reple water?
Hydrophilic heads on plasma membranes attract water. These heads are composed of polar molecules that interact with water molecules due to their similar polarity, allowing water to be attracted to and interact with the membrane.
How are two layers of phospholipids arranged tail to tail in biological membranes?
In biological membranes, two layers of phospholipids are arranged tail to tail with their hydrophobic tails facing inward and their hydrophilic heads facing outward. This arrangement creates a barrier that separates the inside and outside of the cell.
How are phospholipids arranged in cells?
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.
