What part of the lipid likes water?
In general lipids are nonpolar molecule and water is polar and n'er the two shall mix. However, lipids can bond to something like a phosphate group which is polar and the phosphate group will face the water while the nonpolar hydrophobic tail will face away from the water.
Which parts of the phospholipid molecules that make up the plasma membrane face away from the watery environments?
The polar tails face away from the watery environment while the polar heads face the watery environment.
How does laundry detergent work on a molecular level?
The molecule that makes up soap or detergent has a polar head and a nonpolar tail. In chemistry, compounds that are polar like to mix with other polar compounds and compounds that are nonpolar like to mix with other nonpolar compounds. This is why oil and water don't mix. Water is polar and oil is nonpolar. Oil and grease are a nonpolar compounds. When in water the soap molecules will arrange themselves in such a way that the nonpolar tails surround the grease creating a spherical droplet. On the face of this sphere is the polar heads of the soap molecule. This allows it to interact with the polar water. This is how soap and laundry detergent are able to remove oil and grease and wash it down the drain.
Substances inside the plasma membrane are?
Plasma membrane in made up of phospholipid bilayer and proteins. It has a hydrophobic tail facin each other on the bilayer, and polar head that face outside to the polar environment. Proteins such as integral and peripheral proteins are presenting on the membarane.
How do phospholipids help control the passage of materials in and out of the cell?
They have a hydrophilic and hydrophobic region. The hydrophobic regions will face inward in a phospholipid bilayer, and the hydrophilic will face outward. This creates a bilayer that only allows small, nonpolar molecules through. It makes it difficult for larger macromolecules to pass through because the hydrophobic regions will not face the water inside or outside the cell.
What part of a phospholipid is polar and non-polar?
The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.

The head of the phospholipid is?
The head of the phospholipid is polar,it is hydrophilic in nature and hence attracted towards water,which face outwards in plasma membrane of cell

The polar tails face away from the watery environment while the polar heads face the watery environment.

Which part of the phospholipids is attracted to water?
The hydrophilic end of the phospholipid is the end that is attracted to water. Only the hydrophilic end will come in contact with the water. The other, hydrophobic ends, will face inward and touch each other.

They have a hydrophilic and hydrophobic region. The hydrophobic regions will face inward in a phospholipid bilayer, and the hydrophilic will face outward. This creates a bilayer that only allows small, nonpolar molecules through. It makes it difficult for larger macromolecules to pass through because the hydrophobic regions will not face the water inside or outside the cell.
Are non-polar molecules hydrophilic?
No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.
How does the shape of a molecule affect it's polarity?
The shape of a molecule affects its polarity by determining the spatial arrangement of its polar bonds. If a molecule is symmetrical, with polar bonds arranged symmetrically, it will likely be nonpolar overall. However, if the molecule is asymmetrical, with polar bonds arranged asymmetrically, it will likely be polar overall. The polarity arises due to the unevenly distributed electron density caused by the electronegativity difference between the bonded atoms.
What color is a polar bear's face?
The visual answer is that the face is white, and the only black on a polar bear's face is its eyes, nose and mouth. The more technical answer is that a polar bears fur in all actually transparent. Their skin underneath is black. See the related link for a polar bear face picture.
How are phospholipids arranged to form plasma membrane?
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.
