Antioxidants are substances that neutralize free radicals, which are highly reactive molecules that contain unpaired electrons. Free radicals can damage cell membranes, DNA, and other cellular components, leading to oxidative stress and causing cell death. Antioxidants work by donating an electron to a free radical, thereby neutralizing it and impeding further damage. Plant cells are exposed to a variety of environmental stresses, including drought, high temperatures, and exposure to pollutants. These stresses can cause oxidative stress, which can lead to damage to plant cells and reduce the production of secondary metabolites, such as antibiotics and antifungals. Therefore, antioxidants may be beneficial for protecting plant cells under stress and promoting the production of secondary metabolites.

One example of an antioxidant that may protect plant cells under stress is vitamin E. Vitamin E is a fat-soluble vitamin that is widely distributed throughout plant tissues and has been shown to have antioxidant properties. Studies have shown that vitamin E can protect plant cells against oxidative stress caused by drought, high temperatures, and exposure to pollutants. For example, one study found that vitamin E supplementation increased the resistance of Arabidopsis thaliana plants to drought stress. Another study found that vitamin E educed the production of reactive oxygen species (ROS), which are a hallmark of oxidative stress, in tobacco leaves exposed to high temperatures.
