Answer 1

The correct answer is Diffusion.

Key Points:

An essential mechanism by which gases are exchanged in a cell is diffusion.
The difference in concentration pressure is what primarily controls this process.
As a result, the gases shift from a place of high concentration to one of low concentration.
The main time that diffusion occurs in plant cells is during photosynthesis when carbon dioxide diffuses into plant cells through the stomata on the leaf.

Additional Information:

Osmosis is the naturally occurring net movement or diffusion of solvent molecules through a membrane that is selectively permeable, in a direction that tends to balance the solute concentrations on the two sides, from a region of high water potential (region of lower solute concentration) to a region of low water potential (region of higher solute concentration).
Endocytosis is a process through which cells take in foreign material by enveloping it with their membrane.
Absorption: The substance being absorbed's molecules, atoms, and ions move into the medium's bulk phase, which might be solid, liquid, or gas. A chemical or physical phenomenon is called absorption. Absorption is the process through which something completely dissolves into another substance.
