What characteristics of the cell membrane determines what goes into the cell and what doesn't?
The cell membrane's selective permeability is primarily determined by its lipid bilayer structure, which consists of phospholipids with hydrophobic tails and hydrophilic heads. This arrangement allows small, nonpolar molecules to pass through easily, while larger or charged molecules require specific transport proteins or channels. Additionally, membrane proteins play crucial roles in facilitating the transport of substances and in signaling, further regulating what enters or exits the cell. Overall, the combination of lipid composition and protein functions governs the cell's interactions with its environment.

What organelle helps the cell keep its shape and determines what goes in and out of the cell?
The cell membrane, also known as the plasma membrane, is the organelle that helps the cell keep its shape and determines what goes in and out of the cell. It acts as a semi-permeable barrier, regulating the flow of molecules in and out of the cell.
What is the characteristics of cell?
There are many characteristics of a cell. These include the plasma membrane, chromosomes, ribosomes, cytoskeleton, as well as the cytoplasm.
What is a factor that determines whether molecule can cross a cell membrane?
size/ polarity can be the factors
What is the major component of a typical animal cell determines structure and function?
The cell membrane is a major component of an animal cell that determines its structure and function. It acts as a protective barrier, regulates the passage of substances in and out of the cell, and plays a key role in cell communication and signaling.
What organelle determines the structural and functional characteristics of the cell by controlling RNA and protein synthesis?
Nucleus
What characteristics about a cell determine how many materials move in and out?
The cell membrane determines what can move in or out of the cell.
What part of a cell determines what enter a cell?
nucleus and membrane/wall
Which cell part determines what molecules move into or out of the cell?
The Semi-Permiable Cell Membrane
Does prokaryotic cells have a nuclear membrane?
Prokaryotic cell doesnt have a nuclear membrane.
What organelle helps the cell keep its shape and determines what goes in and out of the cell?
The cell membrane, also known as the plasma membrane, is the organelle that helps the cell keep its shape and determines what goes in and out of the cell. It acts as a semi-permeable barrier, regulating the flow of molecules in and out of the cell.
What is a factor that determines of a molecule can cross a cell membrane?
Polarity
What are all the functions of a cell membrane in all cells?
Due to its semi permability a cell membrane controls what goes in and out of the cell..in simplicity it determines what is right to enter the cell.
What part of the cell determines what goes in and out of the cell?
The cell membrane, which is a semi-permeable structure made up of lipids and proteins, regulates what enters and exits the cell. It controls the movement of substances like nutrients, ions, and waste products in and out of the cell to maintain internal balance and proper functioning.
What is a structure in a cell that provides instructions for the cell and determines the characteristics of an organism?
nucleus
What is a factor that determines whether a molecules can cross a cell membrane?
mass
What is the characteristics of cell?
There are many characteristics of a cell. These include the plasma membrane, chromosomes, ribosomes, cytoskeleton, as well as the cytoplasm.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
