Gas exchange during photosynthesis

WebDuring photosynthesis, respiration and transpiration, gas exchange occurs via the stomata and so plants face a trade-off between maximising photosynthesis while minimising transpiration (expressed as water use efficiency, WUE). The ability to cope with this trade-off and regulate photosynthetic rate … WebApr 11, 2024 · All leaf gas exchange and chlorophyll fluorescence measurements were conducted at 27 °C leaf temperature, 1500 μmol m −2 s −1 PPFD, with a leaf-to-air water …

Adaptations of the leaf for photosynthesis and gaseous exchange

WebThe 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. Leaves possess stomata – tiny pores, for gaseous exchange.
