Is a cell required for passive transport?
No. Diffusion (passive transport) can take place without a cell. For example, if you were to put some coloured food dye into a cup of water, the food dye would spread until it eventually was a uniform colour. This is the process of diffusion, which is the movement of a substance down a concentration gradient. Passive Transport means no energy is required.
What term means the diffusion of water?
osmosis
What is passive transport diffusion?
When there is a solution on either side of a barrier (membrane for example) withing a cell, the concentrations of said solution will be different on either side of the barrier. Concentrations do not like to be different and will move from high to low until they are equal. For example, there are sodium ions on either side of a cell membrane. the concentration is higher inside, so to make the concentrations equal, some salt ions move through transmembrane proteins from the inside of the cell to the outside. it's called passive because it doesn't use any energy
Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?
Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.
For diffusion to occur there must be?
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
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.
Explain osmosis diffusion passive transport and active transport?
Osmosis is the diffusion of water molecules through a semi-permeable membrane. Diffusion is a passive transport that goes from a higher concentration area to a lower concentration area.Passive transport means that there is no energy required to move it.
Is a cell required for passive transport?

For example, if you were to put some coloured food dye into a cup of water, the food dye would spread until it eventually was a uniform colour. This is the process of diffusion, which is the movement of a substance down a concentration gradient. Passive Transport means no energy is required.
Movement of large molecules into a cell is called?
hydrogen bondingANS2:Substances are moved into cells by both active transport and passive transport. An example of active transport is "Endocytosis". An example of passive transport is "Diffusion".
What is passive transportation?
Passive transport is a means of moving biochemicals, and other atomic or molecular substances, across membranes. Unlike active transport, this process does not involve chemical energy. Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. An example would be osmosis; in osmosis, water molecules move from an area of high concentration to an area of low concentration. Carrier proteins are sometimes used during passive transport.
What does net diffusion means?
Net diffusion means the total diffusion due to both holes & electrons .
Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
What does net diffusion?
Net diffusion means the total diffusion due to both holes & electrons .
What does latosisima mean?
"Latosisima" does not appear to be a standard word in English or Spanish. It may be a misspelling or a term in another language.
Difference between cv job reference and referee?
CV is latin for curriculum vitae and really means a resume. Referee is someone who is your reference for your next job.
This is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane?
Exocytosis is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane.
Diffusion can take place if the two substances are?
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
