Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules. In plants, the products include a low-molecular-weight sugar (usually sucrose) that is exported to meet the metabolic needs of the many nonphotosynthetic Cited by: 1. Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid, distinguished by their green color, the result of specialized chlorophyll pigments. In plants, choloroplasts occur in all green tissues. The structure of the chloroplast In plants, photosynthesis takes place primarily in leaves, which consist of many layers of cells and have differentiated top and bottom sides. The process of photosynthesis occurs not on the surface layers of the leaf, but rather in a middle layer called the mesophyll (Figure 1).Author: Lisa Bartee, Walter Shriner, Catherine Creech. Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division. However, chloroplasts are larger and more complex than mitochondria, and they perform several critical tasks in addition to the Cited by: 1.

Get this from a library! Chloroplasts. [J Kenneth Hoober] ISBN: OCLC Number: Randy Wayne, in Plant Cell Biology, Publisher Summary. Chloroplasts are organelles specializing in the conversion of radiant energy to chemical energy. The chloroplast is involved in photosynthesis and consequently cells that contain chloroplasts are autotrophic, which means that they are able to make their own food from inorganic molecules by using the radiant energy of sunlight. Mitochondria and Chloroplasts Mitochondria. Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying formation of ATP from the breakdown of glucose is known as cellular : Bartee, Lisa, Anderson, Christine. Chloroplasts are chlorophyll-containing organelles found in plants, algae, and cyanobacteria. Photosynthesis occurs in chloroplasts. Chlorophyll is a green photosynthetic pigment within the chloroplast grana that absorbs light energy for photosynthesis. Chloroplasts are found in plant leaves surrounded by guard : Regina Bailey.

Sidney K. Pierce, Nicholas E. Curtis, in International Review of Cell and Molecular Biology, Abstract. Chloroplasts removed from their species of origin may survive for various periods and even photosynthesize in foreign cells. One of the best studied and impressively long, naturally occurring examples of chloroplast persistence, and function inside foreign cells are the algal. Chloroplasts in vascular plants range from being football to lens shaped and as shown in Figure 1, have a characteristic diameter of ≈ microns (BNID , ), with a mean volume of ≈20 μm 3 (for corn seedling, BNID ). In algae they can also be cup-shaped, tubular or even form elaborate networks, paralleling the morphological diversity found in mitochondria. Chloroplasts (see Figure 41) are disk-shaped structures ranging from 5 to 10 micrometers in length. Like mitochondria, chloroplasts are surrounded by an inner and an outer inner membrane encloses a fluid-filled region called the stroma that contains enzymes for the light-independent reactions of photosynthesis. The book is recommended to readers seeking an overview on chloroplast biology as well as scientists looking for detailed up-to-date information.
