Guard cells are the only epidermal cells to contain chloroplasts. spongy mesophyll and palisade mesophyll of leaves. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. They are double-membrane organelle with the presence of outer, inner and intermembrane space. Each thylakoid is a single, closed compartment. 1. _____ 4. These cells function to open and close stomata. It is oval or biconvex, found within the mesophyll of the plant cell. What two layers of the plant contain chloroplasts? What lies underneath the cuticle: _____ 5. Which number is pointing to the vein or vascular bundle of the leaf? answer choices .

Plastids assist in storing and harvesting needed substances for energy production. 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. 4) The . A chloroplast is a type of plant cell organelle known as a plastid. 3) What two layers of the plant contain chloroplasts? 30 seconds . Thylakoids are disk shaped structures that contain photosynthetic pigments. answer choices . Palisade layer and Spongy layer. palisade and spongy mesophyll. Photosynthesis occurs in eukaryotic cell structures called chloroplasts. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures … These cells function to open and close stomata. 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. ecolink. 1 decade ago. Science - "Cells" Unit test Answers. Relevance. Lv 7. Answer Save. Biology. The inner membrane is folded into many layers. Both layers of the mesophyll contain many chloroplasts. Column shaped cells that lie just under the epidermis. No, viruses are not alive because they rely on a host organism to be able to reproduce. 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. What two layers of the plant contain chloroplasts? In the palisade layer, chloroplasts are lined in columns just below the epidermal cells, to facilitate the capture of light. Q. … The waxy covering of the leaf: _____ 6. In the (a) leaf drawing, the central mesophyll is sandwiched between an upper and lower epidermis. Which two layers of the plant contain chloroplasts? 0 0. ahmed. Chloroplast in a plant cell is a membrane-bound cell organelle, contain chlorophyll pigments that are absent in the animal cell. The inner membrane layers fuse along the edges to form thylakoids. Tags: Question 19 . 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. 2 Answers. : _____ 6.
