Question

Which form of cell transport allows small molecules to move from an area of higher concentration to an area of lower concentration without energy being required from the cell?

Answer 1

Hey Frnd here your answer____________Diffusion for carbon dioxide, oxygen,etc. and Osmosis For water.
Hope this would help

Answer 2

Simple diffusion allows ‘small molecules’ to move from an area of ‘high concentration’ to area of ‘lower concentration’.

Explanation:

• ‘Diffusion’ is defined as the process of particles’ movement from the higher concentration to the lower concentration in a given substance.  

• This is a very essential process, where it enables the molecular movements in and ‘out of the cell’.

• The cell or biological membrane will separate the interior part of the cell into exterior part of the cell.  

• Some of the substances like ‘carbon dioxide and oxygen’ could move ‘across the membrane’ using simple diffusion.
