Active transport requires ATP and a transport channel. The channel is made of proteins.
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
Energy, versus passive in which energy is not used.
Cells prefer to use passive transport because it does not require energy input from the cell. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient. Passive transport is more efficient for moving molecules down their concentration gradient.
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
There are three organells.They are mitochondria,chloroplast and cytoplasm.
Energy, versus passive in which energy is not used.
Active transport requires energy; passive transport does not.
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
All forms of passive transport depend on the movement of molecules or ions across a cell membrane without the use of cellular energy (ATP). This includes processes such as diffusion, osmosis, and facilitated diffusion.

Osmosis does not require ATP so it is a passive transport.Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of cellular energy.
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
Active transport need energy from outside to perform a function whereas in passive transport the function is performed on the principle of physics. for example active absorption of minerals by the plant roots require energy from respiration whereas passive absorption is achieved by law of diffusion.
