• Chloroplasts are double membrane-bound organelles, which generally differ in their shape- from a disc form to round, discoid, oval and also ribbon. (biologystreams.com)
  • The chloroplasts are also double membrane bound organelles. (psebsolutions.com)
  • The material within the chloroplast is called the stroma, corresponding to the cytosol of the original bacterium, and contains one or more molecules of small circular DNA. (wikidoc.org)
  • Comparable to the mitochondrial matrix, the stroma of chloroplast also consists of a double-stranded round DNA, 70S ribosomes, as well as likewise enzymes which are required for the synthesis of carbohydrates as well as healthy and balanced proteins. (biologystreams.com)
  • The space limited by the inner membrane of the chloroplast is called the stroma. (psebsolutions.com)
  • In addition there are flat membranous tubules called the stroma lamellae connecting the thylakoids of the different grana. (psebsolutions.com)
  • The stroma of the chloroplast contains enzymes required for the synthesis of carbohydrates and proteins. (psebsolutions.com)
  • In some algae (such as the heterokonts and other protists such as Euglenozoa and Cercozoa ), chloroplasts seem to have evolved through a secondary event of endosymbiosis, in which a eukaryotic cell engulfed a second eukaryotic cell containing chloroplasts, forming chloroplasts with three or four membrane layers. (wikidoc.org)
  • The chloroplast is contained by an envelope that consists of an inner and an outer phospholipid membrane. (wikidoc.org)
  • Chloroplasts have an inner and outer membrane and resemble round discs. (sciencing.com)
  • It has no definite nucleus, no chloroplasts or no membrane bound organelles (prokaryotic cell). (florafondness.com)
  • Another function knifebot a central vacuole is that it pushes all contents of the cell's cytoplasm against the cellular membrane, and thus keeps the chloroplasts closer to light. (animalsrelocation.com)
  • Chloroplasts have their own genome, which is considerably reduced compared to that of free-living cyanobacteria, but the parts that are still present show clear similarities with the cyanobacterial genome. (wikidoc.org)
  • Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis. (wikidoc.org)
  • It also contains ribosomes , although most of its proteins are encoded by genes contained in the host cell nucleus, with the protein products transported to the chloroplast. (wikidoc.org)
  • Each collection is called a granum (plural: grana) and the thylakoids of different grana are attached by flat membranous tubules known as stromal lamella. (biologystreams.com)
  • Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy and biomass production in all green plants and the animals that depend on them, directly or indirectly, for food. (wikidoc.org)
  • Cells have one chloroplast filling the cell, each with a single pyrenoid. (wikipedia.org)
  • The hormogones (small pieces of trichome with one to many uniform cells) are formed as a result of the death of intecalary cell or by the formation of special biconcave separation discs. (florafondness.com)
  • The cells appear to be empty, but for cup-shaped chloroplasts on the sides nearest. (gov.tt)
  • Chloroplasts are observable morphologically as flat discs usually 2 to 10 micrometer in diameter and 1 micrometer thick. (wikidoc.org)
  • A well-designed reel mower can cut quite tangled and thick tall grass, but this type works best on fairly short, upright vegetation, as taller vegetation tends to be rolled flat rather than cut. (2020incentivos.pt)
  • A disc 2 mm thick, prepared from the substance previously dried at 250 °C for 1 h, has a substantially flat baseline over the range 4000 cm 1 to 620 cm 1. (forexrin.com)
  • Filaments occur either singly or interwoven to form a flat or spongy, free swimming mat. (florafondness.com)
  • Together, these data further demonstrate that the malate shuttle is responsible for the CTM communication from the chloroplast, the energy-generating organelle, hwid the mitochondrion, the energy-transforming organelle, to regulate ROS formation. (threco.com)
  • They are usually found attached to rocks just below the low-tide mark and are easy to observe in the shallow water of the reef flat. (gov.tt)
  • [2] All eukaryote chloroplasts are thought to derive directly or indirectly from a single endosymbiotic event (in the Archaeplastida ), except for Paulinella chromatophora , which has recently acquired a photosynthetic cyanobacterial endosymbiont which is not closely related to chloroplasts of other eukaryotes. (wikidoc.org)
  • Irregular ins shape sometimes with ruffled edges, it is attached to the substrate by a small, disc-shaped holdfast. (gov.tt)
