Diffusion.
Oxygen.
Osmosis. In this process water is moved in or out of the cell to reach an isotonic concentration. Meaning that both sides of the cell membrane will be of equal strength.
Cell death.

Oxygen is able to go into a cell by diffusion. The oxygen molecules are small enough to go through the cell membrane with that process.
This process is called "respiration."
The process that moves oxygen across the cell membrane is called simple diffusion. Oxygen molecules move from an area of high concentration to an area of low concentration without the need for energy input. This process helps maintain the balance of oxygen inside and outside the cell for cellular respiration.
Particles like oxygen are moved into cells through the process of diffusion. This is a passive process where particles move from an area of high concentration to an area of low concentration, crossing the cell membrane. Additionally, specialized proteins like transporters and channels can facilitate the movement of specific particles into cells.
In the sodium-potassium pump, three sodium ions are moved out of the cell and two potassium ions are moved into the cell. This process helps maintain the cell's resting membrane potential and is crucial for nerve and muscle function.
Euglena obtains oxygen through a process called diffusion. It absorbs oxygen from the surrounding water through its cell membrane, which allows gases to pass in and out of the cell. This process enables euglena to survive by taking in the oxygen it needs for respiration.
