Detailed explanation-1: -Expert-Verified Answer. Explanation; -When a substance is of low molecular weight and has a higher concentration of the substance outside the cell as opposed to inside the cell then it is most likely to diffuse into a cell.
Detailed explanation-2: -The molecule most likely to be involved in simple diffusion is water-it can easily pass through cell membranes. When water undergoes simple diffusion, it is known as osmosis.
Detailed explanation-3: -Only the smallest molecules like water, carbon dioxide, and oxygen can freely diffuse across cell membranes. Larger molecules or charged molecules often require an input of energy to be transported into the cell.
Detailed explanation-4: -Under what conditions will a substance be likely to enter a cell through diffusion? When the concentration of the substance is greater outside than inside.
Detailed explanation-5: -Diffusion is an essential process in cells. They need glucose and oxygen for respiration, which move into them by diffusion. Respiration produces carbon dioxide and water which leave cells by diffusion.
