Answer 1

Answer: (D)

All of the above

In grasses and many monocots, the leaf base (petiole) is broad and surrounds the stem as an envelope. Such a leaf base is known as sheathing leaf base. In grasses such as wheat, maize and grass, the sheathing leaf base protects the intercalary meristem. Hence, the plants belonging to family Poaceae have sheathing leaf base.

So, the correct answer is 'All of the above'.
