Transport of which gases is shown by the arrows in the figure?

The image shows a cross-section of a plant leaf with stomata. Arrows indicate the movement of gases into and out of the leaf through these stomata. This process is related to photosynthesis and respiration. Specifically, carbon dioxide (CO2) enters the leaf for photosynthesis, and oxygen (O2) is released as a byproduct. Additionally, water vapor (H2O) is released through transpiration.

Considering the typical gas exchange in plants illustrated by such diagrams, the arrows are most likely representing:

• Carbon Dioxide (CO2): Entering the leaf for photosynthesis.
• Oxygen (O2): Exiting the leaf as a byproduct of photosynthesis.
• Water Vapor (H2O): Exiting the leaf through transpiration, although this is often depicted as a separate process or implied by the stomatal opening.

Given the general context of gas transport in plant leaves, the question most directly refers to gases involved in respiration and photosynthesis.

Ответ: Углекислый газ (CO2) и Кислород (O2)
