What feature of a membrane describes weather molecules can cross the membrane?
The feature of a membrane that determines whether molecules can cross is its selective permeability. This characteristic arises from the lipid bilayer structure, which allows certain small, nonpolar molecules to pass through freely while restricting larger, polar, or charged molecules. Additionally, specific transport proteins facilitate the movement of these restricted molecules across the membrane, either passively or actively. Thus, the composition and arrangement of the membrane's components play a crucial role in regulating molecular transport.
Which feature of a cell membrane determines whether molecules can cross the membrane?
They must either be lipid soluble (e.g. steroids) or very small (e.g. ions).
Does algae have a plasma membrane?
Yes, algae have plasma membranes. The plasma membrane is a key feature of all living cells, including algae, as it acts as a protective barrier, regulates the movement of molecules in and out of the cell, and helps maintain cellular integrity.
Which feature enables the nucleus to send and receive information through the nuclear membrane?
The nuclear pore complex enables the nucleus to send and receive information through the nuclear membrane. This complex acts as a channel that regulates the movement of molecules, such as mRNA and proteins, between the nucleus and cytoplasm.
What is a selectively permeable memberane?
A selectively permeable membrane allows certain molecules or ions to pass through while blocking others based on their size, charge, or other characteristics. This feature helps regulate the movement of substances in and out of cells, maintaining internal balance and supporting essential cellular functions.

permeability
What feature of membrane describes whether molecules can cross the membrane?
permeabiity
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
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.

Feature the plasma membrane that maintains the cell's homeostasis by allowing some molecules into the cell while keeping others out?
Selective permeability otherwise known as semipermeable membrane.
Which feature of a cell membrane determines whether molecules can cross the membrane?
They must either be lipid soluble (e.g. steroids) or very small (e.g. ions).
What characteristic does it called when the cell membrane allows only certain molecules and ions to enter or exit the cell?
Selective permeability is the characteristic of the cell membrane that allows only certain molecules and ions to enter or exit the cell. This feature helps regulate the internal environment of the cell by controlling what substances can pass through.
Does algae have a plasma membrane?
Yes, algae have plasma membranes. The plasma membrane is a key feature of all living cells, including algae, as it acts as a protective barrier, regulates the movement of molecules in and out of the cell, and helps maintain cellular integrity.
Is plasma membrane the feature of eukaryotic cells only?
No.
Which feature enables the nucleus to send and receive information through the nuclear membrane?
The nuclear pore complex enables the nucleus to send and receive information through the nuclear membrane. This complex acts as a channel that regulates the movement of molecules, such as mRNA and proteins, between the nucleus and cytoplasm.
