2. Pear has sclerenchyma stone cells which are crunchy in texture and they are present in the pear.
3. the husk of the coconut is made up of scelerenchyma tissues which is aide of dead cells that gives rigidity and stiffness to the plant. The presence of lignin on the walls of the cells makes it hard too.
