The exchange of gases occurs across the surfaces of stems and roots in addition to leaves. This broader surface area facilitates gaseous exchange throughout the entire plant. While leaves are the primary sites for photosynthesis and gas exchange, stems and roots also play essential roles. Gases like oxygen and carbon dioxide move into and out of plant tissues, supporting various metabolic processes. The significance lies in providing oxygen for cellular respiration, carbon dioxide for photosynthesis, and overall metabolic balance. This distributed gas exchange ensures the plant’s physiological functions, growth, and energy production are sustained across its entire structure.
