Diffusion and active transport are not the same thing.
Diffusion is when molecules pass from an area of high concentration to an area of low concentration. They travel down a concentration gradient. They do this naturally, like if perfume is sprayed at one end of the room, it spreads to the other end, because there is a low concentration of spray at the other end, see?
Active transport is when a cell actively moves molecules from one side of its membrane to the other. It is often travelling up a concentration gradient, so it is going from an area of low concentration to an area of high concentration- the opposite of diffusion.
What else can I help you with?
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
What are the different types of cell transport?
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
What requires energy diffusion fcilitated diffusion osmosis active transport?
Active transport requires energy, typically in the form of ATP, to move molecules across a cell membrane against their concentration gradient. Facilitated diffusion, while it still uses membrane proteins to transport molecules, does not require energy as it follows the concentration gradient. Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, also not requiring energy.
How do proteins and other membrane constituents arrive at the Golgi apparatus?
This occurs by both Cytoplasmic Diffusion and also sometimes by an Active Transport bio-mechanism.
What is it called when materials move from lower to higher concentration?
Specifically Diffusion, but it is also active transport

Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
What are two forms of passive transport of a cell?
Two forms of passive transport (or transport not involving energy/ATP) are diffusion and facilitated diffusion. Another form is osmosis. Also keep in mind that passive transport is for smaller particles.
What are the different types of cell transport?
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
Define and examples of diffusion and indicate why it is also called passive transport?
its the way the body is
Differences between diffusion and active transport?
Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration, while active transport requires energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. Active transport is selective, meaning it can move specific molecules, whereas diffusion is non-selective.
Is oxygen a passive transport or an active transport?
They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.
What is the process in which molecules move in and out of cell?
The process by which molecules move in and out of a cell is called cell transport. This can occur through passive processes like diffusion or facilitated diffusion, where molecules move along a concentration gradient, or through active transport, which requires energy to move molecules against a concentration gradient. Additionally, cells can also use endocytosis and exocytosis to engulf or expel larger molecules or particles.
Define and give examples of diffusion and indicate why it is also called passive transport?
yes they are the same
What is the process by which materials enter and leave the cell through the cell membrane?
Materials enter and leave the cell through the process of passive and active transport. Passive transport includes diffusion, osmosis, and facilitated diffusion, while active transport involves the use of energy to move molecules against their concentration gradient. Additionally, materials can also enter and leave the cell through endocytosis and exocytosis, which involve the cell membrane forming vesicles to take in or expel large particles or molecules.
