Vascular tissue includes xylem, phloem, parenchyma, and cambium cells. Does photosynthesis occur in some vascular tissue cells? Do some of them have chloroplast?
Vascular tissues are made up of xylem and phloem, each of which are complex tissues (having more than one cell type). So some of their parenchyma cells may have chloroplasts.
The bundle-sheath cells are the photosynthetic cells arranged into a tightly packed sheath around the vein of a leaf. It forms a protective covering on leaf vein, and consist of one or more cell layers, usually parenchyma.
I am not sure whether these two "parenchyma"s are the same or not. Are the bundle sheath cells vascular tissue cells?
