Question

which substances should enter into the cell and go out of the cell​

Answer 1

Answer:

Substances move in and out of cells by diffusion down a concentration gradient, through a partially permeable membrane. The efficiency of movement of substances in and out of a cell is determined by its volume to surface area ratio. ... Osmosis is a type of diffusion but refers only to the movement of water molecules.

Answer 2

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
