Micelles are one a one lipid layer with a hydrophillic head on the outside and hydrophobic tails on the inside. Cell membranes require a phospholipid bi-layer, which is two layers with the hydrophobic tails in the center. It creates a "coating" if you will for the cell. If cells were only made of micelles it wouldn't allow for the separation of the inside contents of the cell. Micelles wouldn't work the same way, they would partially integrate with inner contents of the cell creating a huge mess!
Cell membranes are composed of a phospholipid bilayer, which forms a stable barrier due to the hydrophobic tails being shielded from the surrounding water. Micelles are formed by single-layered lipid molecules in aqueous environments, where hydrophobic tails face the center and hydrophilic heads face outward. The structure of micelles is not suitable for forming the stable barrier required for cell membranes.

Do phospholipids form micelles?
No, phospholipids do not typically form micelles. Micelles are formed by surfactant molecules, which have a hydrophobic tail and a hydrophilic head group. Phospholipids, while having hydrophobic tails and hydrophilic head groups, tend to form lipid bilayers, such as in cell membranes.
Are cell membranes only in animals?
Yes -- plant cells have cell walls made of cellulose, instead of cell membranes.
Does fat provide the major material from which cell membranes are made in the human body?
No, fats are not the major material from which cell membranes are made. Cell membranes are primarily composed of phospholipids, which have a lipid component but also include a phosphate group. While dietary fats can contribute to the lipid portion of cell membranes, they are not the major material used for their construction.
Which cell structure does phospholipid affect the function of?
The cell membrane and the membranes of all of their organelles are made of phospholipids.
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
How did cell membranes first appear on Earth?
There is not yet a definitive answer as to how cell membranes first evolved. One hypothesis is that cell membranes are descendant from naturally occurring micelles which combined with the first self-replicating molecules quite coincidentally. Another possibility is that cell membranes evolved as a competetive mechanism through active selection.
Do phospholipids form micelles?
No, phospholipids do not typically form micelles. Micelles are formed by surfactant molecules, which have a hydrophobic tail and a hydrophilic head group. Phospholipids, while having hydrophobic tails and hydrophilic head groups, tend to form lipid bilayers, such as in cell membranes.

What are cell walls and cell membranes made of?
cell
What cell membranes made of?
cells
Are cell membranes only in animals?
Yes -- plant cells have cell walls made of cellulose, instead of cell membranes.
How does detergent affect lipids?
Detergents disrupt the structure of lipid bilayers by interacting with the hydrophobic tails of the lipids, causing them to solubilize and form micelles. This disrupts the integrity of cell membranes, leading to cell lysis and disruption of cellular functions.
What is the cell membranes channels and pumps made of?
Proteins.

If animal cell has cell wall?
Animal cells do not have cell walls--only cell membranes. All cells have cell membranes made of a phospholipid bilayer. Cell walls, which are located outside of a cell's membrane, are made of various materials depending on the type of cell. They are found in plants (cellulose), fungi (chitin) and bacteria (peptidoglycan).
