Answer 1

Answer: (A)

Sclereids are small bundles of sclerenchyma tissue in plants that form durable layers, such as the cores of apples and the gritty texture of pears. Sclereids are variable in shape. The cells can be is odiametric, prosenchymatic, forked or fantastically branched. The cell walls fill nearly all the cell’s volume. The shell of many seeds like those of nuts as well as the stones of drupes like cherries or plums are made up from sclereid.
