Diffusion
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
One method of movement across the membrane is by diffusion, which is related to osmosis.
Gas exchange occurs through the process of diffusion. Oxygen passes from areas of high concentration in the environment to lower concentration in the cell, while carbon dioxide passes from the cell to the environment. This is facilitated by the phospholipid bilayer of the cell membrane.

Substances enter a cell through the cell membrane
The process by which molecules of sugar pass through an animal cell membrane is called facilitated diffusion. In this process, sugar molecules move across the cell membrane with the help of specific transport proteins. These transport proteins create channels for the sugar molecules to pass through, allowing them to replenish the cell's supply of sugar.
Paramecium obtain oxygen through diffusion across their cell membrane. This process allows oxygen to pass from the surrounding water into the cell where it is used for cellular respiration to produce energy.
