WebThe stomata (air holes) on plants are normally open during the day and closed at night. Photosynthesis happens during the day. Photosynthesis Photosynthesis is the way that plants make their food using energy from sunlight. What is the word equation for photosynthesis? WebInvestigating transpiration. Transpiration cannot be measured directly so instead it is measured indirectly, either by measuring the decrease in mass of a plant due to water loss, or by measuring the volume of water absorbed.. Decrease in mass. The decrease in mass of a plant due to transpiration can be investigated using the following method:

"WebPlants in moist environments would require more stomata. This is because “Plants move water from soils to leaves through a passive evapotranspiration process which provides more hydrogen ions for photosynthesis.” (Boyer, 2015). Therefore, water movement is completely reliant on stomata density and water availability. " - How does the stomata open bbc bitesize

WebAug 15, 2024 · Stomata are open during the day because this is when photosynthesis typically occurs. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose, water, and oxygen. Glucose is used as a food source, while oxygen and water vapor escape through open stomata into the surrounding environment. WebStomata have two main functions. First is gaseous exchange i.e. intake of carbon dioxide and release of oxygen. The second is the process of transpiration in plants. Air enters the plant through these openings. The carbon dioxide is used in photosynthesis, which also produces oxygen.
