Plastids assist in storing and harvesting needed substances for energy production. 30 seconds . The study of chloroplast was first carried by a scientist named Hugo Von Mohl in the year 1837.After his study, it was found that the chloroplasts were the type of plastids and hence it was named “Chloroplastids” by a scientist named Schimper in the year 1883. Column shaped cells that lie just under the epidermis. Favourite answer. In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light.
