Molecular Regulation of Iron Homeostasis in Plants
Iron (Fe) is a micronutrient that is essential for plant growth and development. In addition, Fe availability affects not only the yield of crops but also the quality of their derived products (Briat et al. 2015a).This is because Fe acts as a cofactor for several metalloproteins involved in numerous physiological processes such as the respiration, the photosynthesis, …

Respiration In Plants
Let us take a look at the respiratory process in plants. The Process of Respiration in Plants. During respiration, in different plant parts, significantly less exchange of gas takes place. Hence, each part nourishes and fulfils its own energy requirements. Consequently, leaves, stems and roots of plants separately exchange gases.
