A sclereid is a type of sclerenchyma (a plant cell type characterized by having a thick and lignified cell wall) of varying shapes that are typically shorter, with an extremely thick cell wall and <em>whose function is to provide strength and support primarily. Sclereids are also responsible for the gritty texture of pears and guavas. </em>
<em>They are non-living at maturity as they don't require further maintenance, but they maintain the structure.</em>
