Cells contain a certain structure that acts as a gatekeeper in order to maintain homeostasis. This gatekeeper controls what is able to enter and exit the cell. Plant cells produce oxygen as a waste product. What cell structure allows this oxygen to pass into the environment?
The cell structure that allows oxygen to pass into the environment in plant cells is the cell membrane. The cell membrane is selectively permeable, meaning it allows certain molecules, such as oxygen, to pass through while restricting the passage of others. This allows the oxygen produced during photosynthesis to exit the cell and be released into the environment.
