ii dont know u alll out tyhere should know it
Diffusion
No, actually diffusion is a kind of passive transport, and osmosis is a kind of diffusion. Any passive transport can happen without energy (contrary to active transport). Since, all the things you listed were passive transport, they happen down the concentration gradient and need no ATP.
Yes, faciliated diffusion is when a cell uses energy to maintain homeostasis, but regular diffusion is when homeostasis occurs without using energy.
I think the kind of energy you are looking for is mechanical energy.
mechanical energy
Cells do not gain (or use) energy through facilitated diffusion.
It does not require the use of the cells energy.
No, it does not require energy use from the cell.
No, diffusion does not use energy because it is a form of passive transport. The definition (if anybody needs it) is the movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
Diffusion
No. Facilitated diffusion is just diffusion through membrane proteins. But, it is still diffusion and the net movement of molecules is from high to low concentration and therefore does not require added energy. -H. C =)
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
No it does not
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.
Diffusion is an impromptu process in which cells allow certain substances to pass the plasma membrane, and not use any energy to do so.
Particles move through cell membranes w/out the use of energy by cells.
