Gas exchange during photosynthesis
WebJul 3, 2024 · Carbon dioxide and water are converted into glucose sugar and oxygen. Sugar is broken into water and oxygen. Carbon dioxide and oxygen are converted into glucose sugar and water. The balanced chemical equation for photosynthesis is: 6 CO 2 + 6 H 2 O + energy from sunlight → C 6 H 12 O 6 + 6 O 2 2. WebThe process of photosynthesis occurs not on the surface layers of the leaf, but rather in a middle layer called the mesophyll (Figure 6). The gas exchange of carbon dioxide and oxygen occurs through small, regulated …

Compared to atmospheric air, exhaled air contains: less oxygen; more carbon dioxide ; more water vapour ; The composition of inhaled air differs to exhaled ...
WebSep 24, 2024 · All photosynthesis gas exchange systems work by enclosing an entire leaf, or part of a leaf, within a chamber or cuvette. Within the chamber the quantity and quality of the photosynthetic photon flux density (PPFD: the amount of photosynthetically active radiation, PAR, arriving at the leaf within the 400–700 nm wavelength spectrum of … WebMay 14, 2024 · The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Figure 16.2.4.1 Stoma Normally stomata open when the light strikes the leaf in the …
WebGas exchange during photosynthesis. Plant cells photosynthesize when there is enough sunlight; The process requires the uptake of carbon dioxide and the release of oxygen; … WebThese plants do release some oxygen at night when the stomata open and the oxygen can escape. Carbon dioxide is not released during photosynthesis, but small amounts of that gas are emitted both day …
