What is a passive transport and active transport?
A
Passive transport:the movement of dissolved materials through a cell membrane without using cellular energy.Active transport:the movement of materials through a cell membrane using cellular energy
B
Passive transport:the movement of materials through a cell membrane using cellular energyActive transport:the movement of dissolved materials through a cell membrane without using cellular energy.
C
Passive transport:the diffusion of water molecules through a selectively permeable membrane.Active transport:he cell membrane “pick up” molecules outside of the cells and carry them in, using energy.
D
Passive transport:@u@Active transport:*o*
Explanation: 

Detailed explanation-1: -Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.

Detailed explanation-2: -Passive transport is defined as movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side.

Detailed explanation-3: -Passive transport describes the movement of substances across a cell membrane down their concentration gradients, which does not require energy. Cell membranes are selectively permeable, so only certain substances can passively diffuse directly across the membrane.

Detailed explanation-4: -What is Passive Transport? Passive transport is the fundamental movement of ions and other molecular substances within the cells along the concentration gradient, without any external energy. It is also known as passive diffusion.

Detailed explanation-5: -In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).
