You and your lab partner have isolated 20 new mutant yeast strains that are defective in synthesis of threonine, an amino acid. These Thr- mutants do not grow on minimal medium, but they do grow on minimal medium supplemented with threonine. Ten of your Thr- mutants (numbered 1 through 10) were isolated in a strain of mating type a (MAT a). The other 10 Thrmutants (numbered 11 through 20) were isolated in a strain of mating type α (MAT α). You and your lab partner cross each of the MAT a strains to each of the MAT α strains, and you include crosses to the appropriate wild-type strains. Your experimental observations are shown in the table below, where (-) indicates diploids that did not grow on minimal medium and (+) indicates diploids that did grow on minimal medium.

Following are certain statements regarding C3, C4 and CAM plants
a.) The atmospheric CO2 assimilates into the single cell C4 cycle diatoms, C4 conc. Is higher at the external side where the C3 conc. Is higher at the internal side where the CO2 assimilation takes place and the transport to the vascular tissue
b.) In mitochondria, two molecules of glycine yield a molecule of serine with the concurrent release of CO2 and NH4+ by the successive action of the glycine decarboxylase complex Only
c.) Plant with the C4 metabolism need less rubisco than C3 plants to achieve a given rate of Photosynthesis
d.) CAM Plant PEP Case only active during the Dark due to its phosphorylation while C4 PEP Case active throughout the day
