Chloroplasts are roughly 1–2 μm (1 μm = 0.001 mm) thick and 5–7 μm in diameter. These cells function to open and close stomata. The waxy covering of the leaf. They are enclosed in a chloroplast envelope, which consists of a double membrane with outer and inner layers, between which is a gap called the intermembrane space. In the (a) leaf drawing, the central mesophyll is sandwiched between an upper and lower epidermis. Science - "Cells" Unit test Answers. In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures … 1 Answer krishna kishore G. Jul 29, 2016 In a leaf in between the upper epidermis and lower epidermis a large number of parenchyma are arranged which can be viewed in the Transverse Section of a leaf. The mesophyll can be further broken down into two layers, the palisade layer and the spongy layer, both of which are packed with chloroplasts, the factories of photosynthesis. For my connexus friends, Here is an (almost) entire sheet for the Cells unit test. 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.
