What else can I help you with?
Do a plant cell really needs a cell membrane?
yes plant cells needs a cell membrane
Can small hydrophobic molecules cross the cell membrane?
Yes, small hydrophobic molecules can cross the cell membrane.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
What are the functions of cell membrane in all cells?
the cell membrane is like the skin of a cell. it keeps everything in that needs to be in and everything out that needs to be out.
What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
What is a factor that determines of a molecule can cross a cell membrane?
Polarity
What is the process where in the diffusion of water cross a cell membrane?
Osmosis
What are two structures that a material would have to cross to enter the cytoplasm of a plant cell?
In order to enter the cytoplasm of a plant cell, a material would have to cross the plasma membrane and then the cell wall. The plasma membrane regulates what enters and exits the cell, while the cell wall provides structural support and protection.
