These types of cells give pear flesh a gritty texture and make seed coats hard.

A) xylem
B) stomata
C) phloem
D) sclereids
E) fibers

Sclereids are specialized cells in plants that are responsible for making seed coats hard and give fruits such as pear a gritty texture. They have thick cell walls fortified with lignin and often have irregular shapes. Xylem, phloem, stomata, and fibers are not directly responsible for these characteristics of pear flesh.
