Which of the following given facts regarding CAM Plants are TRUE?
a.) The leaves of CAM plants have traits that minimize water loss, such as thick cuticles, large vacuoles, and stomata with small apertures
b.) All CAM plants, the initial capture of CO2 into four-carbon acids takes place at night, and the posterior incorporation of CO2 into carbon skeletons occurs during the day
c.) The CO2 taken up during the night is fixed into malate
d.) Tight packing of the mesophyll cells enhances CAM performance by restricting CO2 loss during the day
