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. Each thylakoid is a single, closed compartment. Plastids assist in storing and harvesting needed substances for energy production. These cells function to open and close stomata. SURVEY . What two layers of the plant contain chloroplasts? Favourite answer. 2 Answers. Science - "Cells" Unit test Answers. Chloroplasts are roughly 1–2 μm (1 μm = 0.001 mm) thick and 5–7 μm in diameter. Palisade layer and Spongy layer. Thylakoids are disk shaped structures that contain photosynthetic pigments. Photosynthesis occurs in eukaryotic cell structures called chloroplasts. In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light. answer choices .

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 cortex of stems often contains chloroplasts as well. Answer Save. 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.
