What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
What includes diffusion osmosis and facilitated diffusion?
These processes involve the movement of molecules across a semi-permeable membrane. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Facilitated diffusion is the passive transport of molecules across a membrane with the help of specific proteins.
Movement through a cell membrane without using energy is?
passive transport, which includes processes like diffusion and osmosis. These processes rely on the natural movement of molecules from an area of higher concentration to lower concentration, and do not require the cell to use energy to facilitate the movement.
What process does not take material into cells?
The process that does not take material into cells is known as passive transport. This includes mechanisms like diffusion and osmosis, where substances move across cell membranes along their concentration gradients without the need for energy input. Unlike active transport, which requires energy to move materials against their concentration gradient, passive transport allows molecules to passively flow into or out of cells based on existing concentration differences.
What happens in a cell transportation lab report?
When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
Under what conditions will passive transport occur?
Passive transport occurs when molecules move across a cell membrane without the use of energy. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, down their concentration gradient. The main types of passive transport include diffusion, osmosis, and facilitated diffusion.

What is the description of passive transport?

Whats the difference between passive transport and active transport?
Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.

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.
What are the two basic ways substances enter or exit a cell?
These are not necessarily the mechanisms, but I believe you are referring to active and passive transport. Active transport uses energy (from adenosine triphosphate, or ATP) to move solutes from an area of low concentration to an area of high concentration This movement is against the concentration gradient, so energy is required. Passive transport is when the solutes basically fall from an area of high concentration to an area of low concentration across a membrane. Since solutes naturally seek to equalize concentration across a membrane, no added energy is required for passive transport.
