How does sunken stomata reduce transpiration
WebTranspiration is the evaporation of water through open stomata, occurring down the water potential gradient.Factors affecting the rate of transpiration:Light intensity - more stomata will be open to take in CO2 for photosynthesis.Temperature - at higher temperatures water particles will have more energy so the rate of diffusion/evaporation will ... WebAug 15, 2024 · The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs. In photosynthesis, plants use carbon dioxide, …

WebC 4 plants reduce the need to frequently open stomata by creating a high carbon dioxide concentration in the bundle sheath cells, which conduct the Calvin cycle. Regardless of photosynthetic pathway, plants can open and close stomata to regulate transpiration rate … Web- sunken stomata are in depressions - the depressions make it difficult for air movement/wind to remove the vapour, it being a factor - the water potential outside leaf …
WebTemperature affects the transpiration rate in two ways. Firstly, at warmer temperatures water molecules move faster, and the rate of evaporation from stomata is therefore much … WebMay 4, 2024 · As transpiration occurs, the air surrounding a leaf becomes increasingly humid, reducing the difference in water potential between the intercellular air spaces and the atmosphere and slowing transpiration. When a breeze is present, however, the humid air is carried away and replaced by drier air.
