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
How do plants obtain the oxygen required for respiration at night when photosynthesis is not occurring?
They store oxygen produced during the day
They switch to anaerobic respiration
Through lenticels and diffusion from air spaces within the plant
They do not respire at night
