The study notes, "We report the first instance of growing chickpea (Cicer arietinum) in lunar regolith simulants. We used soil regeneration techniques common on Earth with LRS for the first time, using both AMF and VC. We also achieved the first documented chickpea yield in an LRS mixture. Our results show that regeneration methods used on Earth soils can help condition lunar regoliths. Despite promising results, all plants in LRS showed signs of chlorophyll deficiency."

Much like me, all you have to do is look at them.

It is on the Moon, it knows it can die due to decompression at any moment and we completely screw up it's circadian cycle with 30+ days. Of course it will be anxious, no need to prove it.
