Diffusion is a method of natural movement of gas molecules from a region of higher concentration to a region of lower concentration. The difference in concentration is called a concentration gradient.
Osmosis is the diffusion of water through a biological membrane. Water molecules move along the concentration gradient from the area of higher water concentration to lower concentration.
Facilitated diffusion is when proteins within the cell carry or escort certain materials or substances in or out of the cell.
What else can I help you with?
All transport through the cell membrane can be classified as?
passive or active transport. Passive transport does not require energy input and includes processes like diffusion and facilitated diffusion. Active transport requires energy input and includes processes like primary active transport and secondary active transport.
What type of transport does not require energy?
Passive transport does not require energy, as it involves the movement of molecules across a cell membrane without the input of energy. This includes processes such as diffusion, osmosis, and facilitated diffusion.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
Is the concentration gradient active or passive in cellular transport processes?
The concentration gradient is a passive force in cellular transport processes.
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)

Does passive transport uses the cell wall?
Passive transport does not specifically involve the cell wall. Passive transport mechanisms, such as simple diffusion and facilitated diffusion, rely on the concentration gradient of substances to move across the cell membrane without requiring energy input from the cell. The cell wall mainly provides structural support and protection to the cell rather than directly participating in passive transport processes.
Is the concentration gradient active or passive in cellular transport processes?
The concentration gradient is a passive force in cellular transport processes.
Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
What two processes transport materials through the semi-permable membrane?
Considering the cell membrane itself, processes include diffusion, osmosis, facilitated diffusion (passive processes that do not require energy) and active transport (an active process that requires energy).
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
