In the (a) leaf drawing, the central mesophyll is sandwiched between an upper and lower epidermis. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Q. 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. _____ 4.
