Length, area, volume relationships Basic properties of populations: mean, variance, standard deviation, standard error Consider two species of succulent plants, a morphotype of plants often associated with CAM photosynthesis. These plants use organic acids to store carbon dioxide at night to use in the light reactions that take place during the day, when stomata are closed. Numerous studies comparing species of the same genus have found that the degree of succulence is correlated with the amount of C02 fixation. Using the data provided, of a sample of five leaves (one leaf from a different individual of each species), and assuming that leaf area is roughly '/2 length x width, and volume is roughly area xthickness, calculate the volume for each individual. Find the mean, variance, standard deviation, and standard error of the length, width, thickness, leaf area, and volume measurement for each species. Which of these parameters has the greatest amount of variation? (indicated by the magnitude of the vaancel Which species do you think will have the greater photosynthetic capacity?
