Does transported substances never physically cross the plasma membrane in endocytosis?
In endocytosis, transported substances are enclosed in vesicles formed from the plasma membrane, which do physically cross the plasma membrane. These vesicles then transport the substances into the cell.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
Is an ability of a plasma membrane to allow some substance to cross across the membrane more easily than others?
Yes, the ability of a plasma membrane to allow some substances to cross more easily than others is called selective permeability. This is due to the presence of specific transport proteins and channels that facilitate the movement of certain molecules while restricting others. The lipid bilayer of the membrane also plays a role in regulating which substances can pass through.
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.

mass
Which cell feature of a membrane describes whether molecules can cross the membrane?
The cell feature that determines whether molecules can cross the membrane is its selectively permeable nature. This property allows the membrane to control the passage of substances based on factors such as size, polarity, and charge. Membrane proteins also play a crucial role in facilitating or restricting the movement of specific molecules across the lipid bilayer.
How do cells control what goes in and out of the membrane?
Through the use of proteins. Most substances pass through the membrane with the aid of a protein and changing the shape or the frequence of that protein determines how much of the substance can cross.
What part of the membrane indicates how easy it is for substances to cross?
Permeability
Ask us is a factor that determines whether a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, like oxygen and carbon dioxide, can easily diffuse through the lipid bilayer, while larger or polar molecules often require specific transport proteins or channels to facilitate their passage. Additionally, the concentration gradient and the presence of membrane proteins can also influence a molecule's ability to cross the membrane.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
Which is a factor that determines wheathe a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, such as oxygen and carbon dioxide, can easily pass through the lipid bilayer, while larger or polar molecules often require specific transport proteins to facilitate their movement. Additionally, the concentration gradient and the presence of channels or carriers also influence a molecule's ability to cross the membrane.
