The term 'Plant Opening' refers to the process of a plant opening its stomata and pores. Stomata are small openings on the surface of a plant's leaves, stems, and other organs that allow for gas exchange. Pores are tiny openings in the epidermis of a plant that allow for the absorption of water and other substances. Plant openings are essential for the survival of a plant as they allow for the exchange of gases and the absorption of water and other nutrients.
