The cell membrane
The organisms get the reactants for cellular respiration through the process of photosynthesis. Glucose and Oxygen are produced by photosynthesis.
The cellular process that maintains homestasis is the plasma membrane or cell membrane. It is the barrier between the cell and its environment and allows steady amount of nutrients to come into the cell no matter what external conditions are.

actually diffusion allows materials to move in and out of the cell
The process for moving cellular wastes across the cell membrane is known as active transport. Active transport is a source of energy that allows molecules to move from low concentrations to high concentrations, and provides the needed boost to move the molecules uphill.
Diffusion is the process of cell transfer within the nervous system. It is diffusion of the ions that allows for transport and solubility to complete the process. Osmosis is used in other cellular areas.
The plasma member is a selectively permeable membrane which allows the entry and exit of substances in and out of the cell through the process of diffusion.
Endocytosis is a process which allows a cell to engulf molecules in their entirety and surround those molecules in a membrane. Transport is when small molecules can actively transport through a cellular membrane and come out again.
cellular respiration.
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
it allows some but not all materials to cross
A selectively permeable membrane allows SOME but not ALL materials to cross.
