What two layers of the plant contain chloroplasts? : _____ 6. What two layers of the plant contain chloroplasts? Palisade layer and Spongy layer. Tags: Question 19 . _____ 4. The inner membrane layers fuse along the edges to form thylakoids. 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. 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. A chloroplast is a type of plant cell organelle known as a plastid. Both layers of the mesophyll contain many chloroplasts. _____ 7. Which two layers of the plant contain chloroplasts? upper and lower epidermis. 3) What two layers of the plant contain chloroplasts? It is oval or biconvex, found within the mesophyll of the plant cell. 1. These cells function to open and close stomata. ecolink. Relevance. 1 decade ago. 1 decade ago. 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. Lv 7. 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. cuticle and upper epidermis. Q. In the (a) leaf drawing, the central mesophyll is sandwiched between an upper and lower epidermis. Column shaped cells that lie just under the epidermis. Chloroplasts are roughly 1–2 μm (1 μm = 0.001 mm) thick and 5–7 μm in diameter. Outer layer of the vein: _____ 8. No, viruses are not alive because they rely on a host organism to be able to reproduce. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures … In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. The cortex of stems often contains chloroplasts as well. The inner membrane is folded into many layers. What two layers of the plant contain chloroplasts? Answer Save. For my connexus friends, Here is an (almost) entire sheet for the Cells unit test. SURVEY . Biology. 0 0. ahmed. 30 seconds . What lies underneath the cuticle: _____ 5. Photosynthesis occurs in eukaryotic cell structures called chloroplasts. spongy mesophyll and palisade mesophyll of leaves. These cells function to open and close stomata. Favourite answer. Each thylakoid is a single, closed compartment. In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light. They are double-membrane organelle with the presence of outer, inner and intermembrane space. answer choices . The waxy covering of the leaf: _____ 6. Science - "Cells" Unit test Answers. … 2 Answers. The waxy covering of the leaf. Plastids assist in storing and harvesting needed substances for energy production. The outermost layer of cells: _____ 5. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. Chloroplast in a plant cell is a membrane-bound cell organelle, contain chlorophyll pigments that are absent in the animal cell. answer choices . Which number is pointing to the vein or vascular bundle of the leaf? Notice that the chloroplast has two membranes. Thylakoids are disk shaped structures that contain photosynthetic pigments.
