Which specific adaptation allows some plants to minimize water loss while still facilitating gas exchange for respiration?
Increased leaf surface area
Absence of stomata
Continuous, high rates of transpiration
Stomatal opening primarily at night in CAM plants

A researcher observes that a plant placed in a sealed chamber shows a net decrease in CO2 levels during the day but a net increase at night. What can be inferred about the metabolic processes occurring?
The plant is only respiring, both day and night.
The plant is only photosynthesizing, both day and night.
Photosynthesis exceeds respiration during the day, while respiration exceeds photosynthesis at night.
Respiration exceeds photosynthesis during the day, while photosynthesis exceeds respiration at night.
