Hydrophobic means water fearing tails and hydrophilic means water loving heads
First of all, these terms are involved when you are looking at the cell membrane. The structure of the cell membrane is called a phospholipid bilayer. Which means that the cell membrane is actually made to two layers and not one.
If you take a look at the image, you will see that the little white sphere shaped objects are the hydrophilic heads, and the two little string-like objects attached to the hydophilic heads are the hydrophobic tails. All of the other stuff in the image is all of the extracellular proteins and such. But yes, as the previous answerer said. The hydrophilic heads are on the outer part of the bilayer because they are "water loving". Whereas the hydrophobic tails are on the inner part of the bilayer for two reasons. First, they are hydrophobic or "water fearing" so they will repel water. An example of hydrophobic is oil in water. The oil will form blob-like shapes in the water. Second, the hydrophobic tails also have a somewhat attraction to each other.

How are phospholipids arranged in a plasma membrane and what is their role in maintaining the structure and function of the membrane?
Phospholipids in a plasma membrane are arranged in a bilayer, with the hydrophilic heads facing outward and the hydrophobic tails facing inward. This arrangement helps maintain the structure of the membrane and allows it to be selectively permeable, regulating the passage of substances in and out of the cell. The phospholipids also play a role in cell signaling and maintaining the integrity of the membrane.

This arrangement helps maintain the structure of the membrane and allows it to be selectively permeable, regulating the passage of substances in and out of the cell. The phospholipids also play a crucial role in cell signaling and maintaining the integrity of the membrane.
How are phospholipids oriented in the plasma membrane and what role does this orientation play in the structure and function of the membrane?
Phospholipids in the plasma membrane are arranged in a bilayer, with the hydrophilic heads facing outward towards the watery environment and the hydrophobic tails facing inward. This orientation helps maintain the integrity and fluidity of the membrane, allowing it to selectively control the movement of substances in and out of the cell.
What makes up most of the molecules in the plasma membrane?
The main component of the cell membrane is phospholipids. These are molecules with a polar (hydrophilic, water-loving) head composed of a phosphate (and usually a choline) and a non-polar (hydrophobic, water-hating) tail composed of fatty acids. In the cell membrane, these phospholipids are arranged in a bilayer - with heads facing the outside and the tails facing each other in the centre of the membrane.
Which hydrophilic heads face outward face and hydrophobic tails face inward?
In a phospholipid bilayer, the hydrophilic heads face outward towards the water environment, while the hydrophobic tails face inward, creating a hydrophobic core within the membrane. This arrangement helps to stabilize the structure of the membrane and maintain cell integrity.
Does a plasma membrane consist of phospholipds?
Yes, a plasma membrane is a phospholipid bilayer, meaning it is made up of two layers of phospholipids. The hydrophobic tails face inward, and the hydrophobic heads face out to either side of the membrane.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
Why are the outside heads of phospholipids located on the outside of the cell membrane?
Tails are Hydrophobic
Which molecule has hydrophilic and hydrophobic properties and would be found in plasma membranes?
Phospholipids have hydrophilic ("water-loving") heads and hydrophobic ("water-fearing") tails, which allow them to form the lipid bilayer of plasma membranes. This dual nature of phospholipids helps create a barrier that is selective about what can enter or leave the cell.
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.

How is the plasma membrane organized?
The cell (plasma) membrane is organised into a bilayer of phospholipids. This means that the hydrophilic (water-lover) polar heads of the phospholipids face out, and the hydrophobic (water-hating) non-polar tails face towards each other in the centre of the layer. Interspersed within the phospholipids of the membrane are proteins (such as protein channels), cholesterol and carbohydrates.
What form the majority of the plasma membrane of cells?
The majority of the plasma membrane of cells is composed of a phospholipid bilayer. This bilayer consists of two layers of phospholipid molecules, with the hydrophobic tails facing inward and the hydrophilic heads facing outward. Additionally, membrane proteins such as receptors, channels, and transporters are embedded within this lipid bilayer.
Does the cell membrane consist of two lipid layers?
Yes, the cell membrane is made up of two layers of phospholipids called a lipid bilayer. These phospholipids have hydrophobic tails that face inward and hydrophilic heads that face outward, providing the structure of the membrane.
The plasma membrane contains two kinds of lipids?
Phospholipids. They feature a phosphate group at one end of each molecule. The heads, or phosphate ends, are hydophilic ("water-loving") and the tails are hydrophobic ("water-fearing"), which keeps them oriented correctly, with the tail ends always inside the lipid layer.
