What kind of substance cannot pass through the cell membrane?
lipids, and ribosomeslipids
How are selectively permeable membranes essential for life?
Because they allow the passage of water, lipids, nutrients and ions into the cell while checking large molecules and larger polar molecules. These are controlled by transport proteins in the cell membrane. Also the membrane can surround molecules and pinch off so that molecules can be transported in and out of the cell.
What are the membranes of what have tiny pores that allow the passage of water molecules?
Plant leaves. The pores are called stomata.
Are lipids organic or inorganics?
Lipids are organic molecules that are naturally occurring and they are insoluble in water.
Are primary water-insoluble components of cell membranes?
The correct answer is Phosphorous
Are lipids similar to water molecules?
Lipids are hydrophobic or ambiphilic small molecules. In water, hydrophobic lipids such as oils and fats clump up and separate from the water. In water, ambiphilic lipids such as phospholipids form bilayer structures; the body of living creatures uses these bilayer structures to form cell membranes and vesicles.

Lipids are organic molecules that are naturally occurring and they are insoluble in water.
What are the roles of lipids?
Lipids can be used to store energy. Some lipids are important parts of biological membranes and water proof coverings.
What do lipids repel?
Lipids are hydrophobic, which means they do not dissolve in water. Th characteristic is important because it always lipids to serve as bariers in biological membranes
Are primary water-insoluble components of cell membranes?
The correct answer is Phosphorous
Lipids are described as being what or water-hating?
Lipids are hydrophobic macromolecules. Literally it means "fear of water", and that water cannot easily diffuse across lipid membranes.
What polar molecules are attracted to water?
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Large biological molecules known as lipids?
A lipid is a large non polar biological molecule which is not a polymer. Insoluble in water and store energy and make up the cell membranes. So yes you are correct.
How are lipids different from other organic molecules?
they are not soluble in water
