Does passive transport move along concentration gradient?
Yes, passive transport moves along the concentration gradient, meaning that substances move from an area of higher concentration to an area of lower concentration without the input of energy. Examples of passive transport include diffusion and osmosis.
What is the movement of molecules from areas of higher concentration to lower concentration until equilibrium is met?
The movement of particles from an area of high concentration through a semi-permeable membrane to an area of low concentraton is the process of diffusion. I'm sorry but I do not think that answer is good enough. It is a form of diffusion, where only small particles, small enough to pass through the membrane can get through. When I was in school the statement above was the definition of osmosis, the whole point being it was diffusion through a semi-permeable membrane, selecting for only small enough particles. It seems some time between 1992 and 2003 the definition was changed to the movement of water, and not particles and now in 2010 the definition is the movement of solvents. I would like to know how and why the definition osmosis was changed, why and what is the justification? I would also like to know why the original meaning of osmosis, which made perfect sense, has been changed to "it's the definition of diffusion and not osmosis any more", when in fact it isn't a clear enough word to describe the process? Surely the new definition of osmosis is also diffusion?
What term do scientists use to describe the cell membrane about diffusion and osmosis?
Scientists typically refer to the cell membrane as selectively permeable, meaning it allows certain substances to pass through while restricting the movement of others. This property facilitates the processes of diffusion and osmosis, which are essential for the cell to maintain its internal environment.
Is xylem an osmosis?
xylem is transport tissue made up of dead cells within vascular plants whose primary responsibility is to transport water to all the parts of the plants. osmosis is the diffusion of water across a semi-permeable membrane down the water potential gradient, meaning the water moves to from an area that has a high concentration of water to an area that has a low concentration of water.
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.
Diffusion and osmosis prefix meaning inside?
The prefix meaning "inside" in both diffusion and osmosis is "intra-." This prefix is used to indicate movement or passage within a structure or system.
Is moss a vascular or a nonvascular plant?
Moss is non-vascular. Because a moss is non-vascular, it relies on osmosis and diffusion to receive mainly oxygen and carbon dioxide from the air for nutrients.
What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
What only certain materials can enter the cell?
Cell membranes are selectively permeable, meaning only certain materials can enter the cell. This selective permeability allows cells to regulate the movement of substances in and out of the cell to maintain internal balance and proper functioning. Substances such as water, ions, and small molecules can pass through the membrane via various transport mechanisms like diffusion, osmosis, and facilitated diffusion.
What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
When does the passive transport of a molecule from the inside of a cell to the outside occur?
Passive transport of a molecule from inside a cell to the outside occurs when the molecule moves down its concentration gradient, meaning it moves from an area of higher concentration to an area of lower concentration. This process does not require energy, as it relies on the natural tendency of molecules to spread out. Common mechanisms for passive transport include diffusion and facilitated diffusion through protein channels.
How is omosis defined?
Osmosis is the diffusion of fluid through a semipermeable membrane.
Does passive transport move along concentration gradient?
Yes, passive transport moves along the concentration gradient, meaning that substances move from an area of higher concentration to an area of lower concentration without the input of energy. Examples of passive transport include diffusion and osmosis.
How the terms in each pair differ in meaning of osmosis and diffusion?
Osmosis is the diffusion of water through a selectively permeable membrane. Diffusion refers to the simple property of moving from an area of high concentration to an area of low concentration so that the concentration of the total area will be equal and balanced (at equilibrium). Diffusion can occur with any substance and does not require but can involve a permeable membrane.
The movement of molecules from high concentration to low concetration?
This process is called diffusion. It occurs when molecules move randomly and eventually spread out to areas of lower concentration to achieve an equilibrium. Diffusion is a passive process, meaning it does not require energy input.
What is the movement of molecules from areas of higher concentration to lower concentration until equilibrium is met?
The movement of particles from an area of high concentration through a semi-permeable membrane to an area of low concentraton is the process of diffusion.
