Abstract

Silica is present in significant amount in mature guard and subsidiary cells of stomata, in trichomes and silica cells, and in the walls of long eidermal cells of Avena. No silica was detectable in cork cells of cork-silica cell pairs. Silica must be accumulated in these specialized epidermal cells quite rapidly.
