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.

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
What is the movement of substances without the use of energy by the cell?
Passive transport.
What passive transports function?
Passive transport refers to the movement of biochemicals and other atomic or molecular substances across cell membranes. The function of the passive transport is that it is used in filtration and osmosis processes.
What separates active transport from passive transport?
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
What kind of substances are likely to move via passive transport through phospholipod bilyer?
transport of materials through cell wall without energy.
What occurs if substances are too large to pass through the cell membrane by active or passive transport?
passive transport
What is the movement of particles from high to low concentrations that does require energy?
Passive Transport.

The transport in which substances move from lower to high concentration is what?
The textbook definition of "passive transport" is moving from high to low concentration. You mean passive diffusion..
What is passive membran transport?
The diffusion of substances across a membrane is called passive transport. Molecules move from where the substance is more concentrated to where it is less concentrated.

What substances enter the cell by attachment to a passive transport protein carrier?
Phospholipids

Is osmosis form of active transport or passive transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
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 name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
