Question 6
The gritty texture in the flesh of a pear is caused by:
The right answer is the one marked above.
Sclereids. Short, irregular sclerenchyma cells with extremely thick walls, scattered singly or in small groups through the fruit wall.
Sclereids also make the shell of a coconut, kaduru and mango, and the seed coats of dates and coffee. A round thick-walled cell resists being crushed from any direction.
