Silica is deposited in the outermost layer of the tissue (epidermis) making a rigid barrier called Phytoliths. Most Si is cross linked with hemicellulose in cell walls to increase the elasticity. This mechanical strength & elasticity keeps the plant erect for enhanced photosynthesis, helps it hold the fruit load more comfortably.
This provides a strong defense during biotic stress [pests & pathogens]. The attacking pests tries to eat the tissue [biting], suck the fluid [piercing], or burrow inside [boring]. The strong & rigid silica wall blocks it and also damages the teeth/stings of the infesting pests. Naturally this reduces the food intake, growth longevity, and population growth of pests. The Silica Wall also blocks the fungi from reaching the tissues making them less susceptible to enzymatic degradation caused by pathogens.
Apart from that further accumulation of Silica is found in the fungus sites increasing the resistance to pathogen invasion.
It has been widely reported that Si is able to suppress abiotic physical stress, such as drought, high/low temperatures, typhoons, inadequate sunshine, UV etc. The strong cell wall are better at managing water balance inside the cells. Under physical stress the cells are able to maintain their structure for a longer duration and plants does not droop easily maintaining the structural integrity for a longer duration.
