Scientists have studied the feasibility of plants growing on the moon through experiments. It shows that Arabidopsis plants grow slower in lunar soil samples and show more signs of stress than in earth volcanic ash. These lunar soils are samples collected during the Apollo mission. The authors point out that these findings suggest that in order for plants to grow effectively in lunar soil, the interaction between plants and lunar soil needs to be further studied.
