The cell membrane does not use energy.
It does not require the use of the cells energy.
active transport
i think yes
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
Facilitated diffusion
cell membrane pumps use energy to force molecules in a direction opposite of natural.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
passive transport
No, it does not require energy use from the cell.
It does not require the use of the cells energy.
if it is against a concentration difference.
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
It is called passive diffusion.

Movement of water across the cell membrane
Unicellular organisms do not use energy for everything. For instance, diffusion across the cell membrane of the organism does not require the use of energy.
