The correct answer is During the night.

Key Points

• Desert plants primarily take up carbon dioxide (CO₂) during the night through a unique adaptation called Crassulacean Acid Metabolism (CAM). This helps them conserve water in arid environments.
• During the night, stomata (small pores on leaves) open to absorb CO₂, which is stored as an organic acid. This process minimizes water loss since temperatures are cooler and humidity is higher at night.
• During the day, the stomata remain closed to prevent water loss, and the stored organic acids are broken down to release CO₂ for photosynthesis. This ensures efficient water use.
• This adaptation is particularly important in deserts, where water is scarce, and high daytime temperatures can lead to excessive water loss through transpiration.
• Hence, the statement "During the night" is correct, while "During the day" is incorrect as desert plants do not open their stomata during the hot daytime to avoid water loss.

Additional Information

• Crassulacean Acid Metabolism (CAM):
• CAM is a specialized photosynthetic pathway that enables plants to open their stomata at night to take in CO₂ and store it as organic acids.
• During the day, the stomata close, and the stored organic acids release CO₂ for photosynthesis.
• CAM is common in desert plants like cacti, agave, and succulents, as well as epiphytes.
• Desert Plant Adaptations:
• To survive in arid conditions, desert plants exhibit adaptations like waxy leaf coatings, reduced leaf size, and deep root systems.
• These adaptations minimize water loss and maximize water uptake.
• Stomatal Function:
• Stomata are tiny pores found on the surface of leaves, responsible for gas exchange.
• In desert plants, stomata open at night to conserve water, unlike most plants that open stomata during the day.
• Examples of CAM Plants:
• Cacti: Adapted to extreme arid conditions, storing water in their stems and performing CAM photosynthesis.
• Agave: Used for producing tequila and is highly drought-resistant.
• Succulents: Store water in their leaves and thrive in dry climates.
