Mary still doesn’t have to make anything special happen to her brain have knowledge of anything else. She can still understand photosynthesis without photosynthesising.
She can understand the sequence of chemical reactions that comprises the Calvin cycle just as she can understand what neural impulses occur when red light strikes retinal rods, but she can’t form the memory of either one occurring within her body.
Which, yet again, only matters if there is something special about qualia that requires memory or instantiation in the body to be understood. She can understand the Calvin Cycle full stop.
