It's called membrane potential.
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.
In fact, polar molecules can pass through cell membranes with the help of specific transport proteins that facilitate their movement. These transport proteins act as channels or carriers to allow polar molecules to cross the hydrophobic membrane. Therefore, polar molecules can indeed pass through cell membranes under certain conditions.
also can be known as polar head since phosphate is polar found in phospholipid bilayer also can be known as polar head since phosphate is polar found in phospholipid bilayer Was this right? i would like to know...
This description matches a phospholipid molecule, which is a key component of cell membranes. The polar head of the phospholipid is hydrophilic, meaning it interacts with water, while the nonpolar tails are hydrophobic, meaning they repel water. This unique structure allows phospholipids to form a lipid bilayer in cell membranes, with the polar heads facing outward towards water and the nonpolar tails pointing inward, creating a barrier that separates the inside and outside of the cell.
Polar bodies are produced during the process of oogenesis to ensure that the developing egg cell receives most of the cytoplasm and organelles needed for successful fertilization and embryo development. The polar bodies contain a small amount of genetic material and are not needed for reproduction, so they typically undergo programmed cell death (apoptosis) to recycle their resources for the benefit of the viable egg cell.
No.
Phospholipids :)
they have a polar head and non-polar tails
subpolar low
The Ferrell cell sits between the polar cell and Hadley cell. It is fueled by atmospheric circulation patterns that transport air between the two cells. Air moves poleward from the Hadley cell and equatorward from the polar cell, interacting within the Ferrell cell to form a complex system of atmospheric circulation.
The three major convection cells in the atmosphere are the Hadley cell, Ferrel cell, and Polar cell. The Hadley cell is near the equator, the Ferrel cell is mid-latitude, and the Polar cell is near the poles. These cells are responsible for redistributing heat and moisture around the globe.
The Polar cell lies to the north of the Polar jet stream in the atmosphere. This cell is characterized by cool air sinking at the poles, moving towards lower latitudes at the surface, and then rising at around 60° latitude to complete the circulation loop.
During oogenesis, the polar body is a small cell that is formed as a byproduct when the egg cell divides. The polar body typically does not have the ability to develop into a mature egg cell and eventually disintegrates.
It would dissolve in water or in polar liquids and would not be recognisable as a cell.
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
hadley cell, ferrell cell, polar cell
Yes silly.
