plants.Scientists studying themechanisms involved in these increases examined a variety of species and found that when plants areexposed to elevated levels of CO₂,there is an increase in the number of chloroplasts per cell.To investigatewhether the elevated levels of CO₂have a similar effect on the number of mitochondria in plant cells,thescientists then selected six of these species to quantify the number of mitochondria per cell when the plantswere exposed to both normal and elevated levels of CO₂(Table 1).  \nTABLE 1.AVERAGE NUMBER OF MITOCHONDRIA IN PLANTS EXPOSED TO  \nNORMALAND ELEVATED

\n(d)The leaves of a particular plant species are typically green,but scientists notice a plant in1 pointwhich the leaves have white stripes.They determine that the stripes result from amutation in mitochondrial DNA that interferes with the development of chloroplasts.Thescientists crossed plants using pollen from the plant with white-striped leaves and ovulesfrom a plant with green leaves.Predict the phenotype(s)of the leaves of offspringproduced from this cross.  \n\n| ·The leaves will be (all)green/not have white stripes.   |  |\n| --- | --- |\n| Provide reasoning to justify
