s: Microplastics will coexist with us humans for a long time, however there is a lack of research on the impact of non-biological and biodegradable microplastics (NMP vs BMP) on plants. In this paper, 180 articles about the effects of NMP and BMP on terrestrial plants were studied by a meta-analysis. The results showed that there is a significant difference between the effects of NMP and BMP on seed germination (Q b=70.25, P<0.001), while NMP and BMP significantly inhibited seed germination rate (-1.34% and -4.69%, respectively).Microplastics induced a significant increase of 128.51% (P<0.05) in plant reactive oxygen species (ROS), while NMP and BMP led to a significant different effects on plant ROS (133.19% and 15.96%, respectively, Q b=117.28, P<0.001). Excessive ROS can lead to oxidative stress in plants, inducing increment of lipid peroxidation in cells or tissues, namely malondialdehyde (MAD, Toxicity), the end product of lipid peroxidation in plants. NMP and BMP increased MAD differently, by 9.29% and 6.01%, respectively. NMP mitigated MAD-induced toxicity through stomatal conductance limitation, whereas BMP employed non-stomatal restriction mechanisms to alleviate microplastic stress. BMP used a pattern that increased the root-shoot ratio, while NMP used a pattern that decreased the root-shoot ratio.
