Definition Diffusion Passive Transport
It is a process in which a molecule or ion passes through a cell membrane via a concentration gradient.
Definition diffusion passive transport. What is passive transport. It is also known as passive diffusion which forms a region of high concentration to the region of low concentration. It s like moving from the train to the platform of a subway station or stepping out of a crowded room. Diffusion is a passive process of transport.
A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. Passive transport also known as passive diffusion is a process by which an ion or molecule passes through a cell wall via a concentration gradient or from an area of high concentration to an area of low concentration. This technology may be used to develop nutrient management thresholds for streams based on comprehensive measures of nutrient assimilative capacity. For example a passive diffusion periphytometer is used to assess algal nutrient limitation and assimilation capacity in streams.
Definition of passive transport. In passive transport substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. A physical space in which there is a different concentration of a single substance is said to have a concentration gradient.
