What is the function of Crassulacean acid metabolism CAM in plants?
Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that exploits a temporal CO2 pump with nocturnal CO2 uptake and concentration to reduce photorespiration, improve water-use efficiency (WUE), and optimize the adaptability of plants to hotter and drier climates.
Which plant is known as Crassulacean acid metabolism?
Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads). CAM plants close their stomata during the day and take up CO2 at night, when the air temperature is lower.
What is a property of the Crassulacean acid metabolism CAM adaptation?
Which of the following is a property of the Crassulacean acid metabolism (CAM) adaptation? Choose 1 answer: Choose 1 answer: A. =CAM plants have stomata that open only during the day.
What is the process of Crassulacean acid metabolism?
Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night.
What is the significance of Crassulacean acid metabolism?
Crassulacean acid metabolism is a carbon uptake system utilized by many succulent plants; these plants fix carbon dioxide during the night when evapotranspiration is relatively low, storing it as organic acids.
What is Crassulacean acid metabolism pathway?
What are the significances of CAM?
Crassulacean acid metabolism (CAM) is a major physiological syndrome that has evolved independently in numerous land plant lineages. CAM plants are of great ecological significance, and there is increasing interest for their water-use efficiency and drought resistance.
What is the characteristics of CAM plants?
CAM plants often show xerophytic features, such as thick, reduced leaves with a low surface-area-to-volume ratio, thick cuticle, and stomata sunken into pits.
