WebFeb 11, 2015 · The concentration gradient therefore represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient. Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached. Rogan T. · 18 · Feb 11 2015.

Passive transport and active transport across a cell membrane …

WebAnswer: Two conditions must be met for a substance to enter a cell by diffusion. The cell's membrane must be permeable to that particular substance. This means, that substance must be able, somehow, to cross the membrane without breaking it. The concentration of the substance inside the cell is l... WebJun 21, 2024 · How do materials move in and out of cells? Substances move in and out of cells by diffusion down a concentration gradient, through a partially permeable membrane. This is called assisted diffusion or active transport. Osmosis is a type of diffusion but refers only to the movement of water molecules. bird that sounds like a small dog barking

How do substances get into, out of and around our bodies?

Webthe cell. These substances pass into or out of the cell by diffusion, using passive transport. Substances moving into the cell are needed by the cell, and substances moving out of the cell are not needed by the cell. Study the diagram below.
