This is a double stained transverse section through a leaf of Bromus a grass with typical C3 photosynthesis. There are two sheaths around the vascular tissue, an outer sheath made of parenchyma cells and the inner one called the mestome sheath. Its cells resemble sclerenchyma but they are not because the cells are living and they allow transport across the mestome sheath. What can you say about the distribution of chloroplasts in this section?
