Water molecules can pass into a cell, while larger molecules cannot. Which feature of a cell allows this to be true?

Answers

Answer 1
Answer: The selective permeability of a cells membrane determine what size and type of molecules can enter or not.  If a molecule has a charge and the membrane has a neutral charge the molecule has a harder time diffusing through.  The differences in charge affect permeability through a cell membrane. 
Answer 2
Answer: The cell has a semi-permeable membrane that allows water molecules to pass in a cell while larger molecules cannot. Lipid bilayer is an example of a biological semi-permeable membrane. The diffusion of water is called osmosis. Solutes such as salt and other contaminants are filtered.

When particles move out of a cell through facilitated diffusion, the cell A. first gains and then uses energy
B. does not use energy
C. uses energy
D. uses energy

Answers

When particles move out of a cell through facilitated diffusion, the correct answer B. is the cell does not use energy.

Facilitated diffusion is diffusion mediated via way of means of delivery proteins. The materials flow down the attention gradient from better to decrease attention so it does now no longer require energy.

What is Facilitated diffusion?

Facilitated diffusion (additionally referred to as facilitated shipping or passive-mediated shipping) is the system of spontaneous passive absorption (in place of lively shipping) of molecules or ions throughout an organic membrane through precise transmembrane essential proteins. Facilitated diffusion is an instance of passive shipping. Materials pass into or out of cells thru channel proteins. The debris pass from regions of excessive attention to regions of low attention.

Thus it is clear that when particles move out of a cell through facilitated diffusion, the cell does not use energy.
