Read the following statements and choose the correct option: 1.The mesophyll is composed of palisade and spongy parenchyma. 2.The palisade parenchyma is located below the spongy parenchyma. 3.The spongy parenchyma has large spaces and air cavities between cells. 4.The mesophyll carries out photosynthesis. 5.The spongy parenchyma is arranged vertically and parallel to each other.

Step-by-step solution

Mesophyll, which possesses chloroplasts and carry out photosynthesis, is made up of parenchyma. It has two types of cells – the palisade parenchyma and the spongy parenchyma,There are numerous large spaces and air cavities between these cells," the palisade parenchyma is located above the spongy parenchyma, and the palisade parenchyma, not the spongy parenchyma, is arranged vertically.
