Photosynthesis occurs in the organelle called the chloroplast. The chloroplast contain the chlorophyll needed to capture the light energy so that it can be processed into energy and food for the plant.Continue Reading
Chloroplasts are made up of small sacs called thylakoid membranes. Each of these flat pancake-like membranes has photosystems set in a ray-like pattern to better capture and hold the light energy for use.
Chloroplasts are a type of plastid that circulate and move around inside the plant cells. These organelles reproduce by pinching themselves in two. This process occurs when a plastid dividing ring forms around the center of the chloroplast, then slowly begins to add pressure to the organelle until it splits under the ring leaving two chloroplast where there had been only one.
Chloroplasts cannot be made by the plant cell; instead, organelles must be inherited by each daughter cell during division. The chloroplast contains its own DNA, sometimes referred to as ctDNA or cpDNA, or plastome.
All of the genetic information is contained in one ring anywhere between 120,000 and 170,000 base pairs long. The chloroplast DNA was first proven to exist in 1962, but was not sequenced until 1986 by two Japanese research teams. Most of the DNA sequencing that has occurred for this comes from land plants or algae.Learn more about Cells
The Calvin cycle takes place in the stroma of the chloroplast. The stroma is the fluid-filled section of the chloroplast in which the thylakoids stack up in structures known as grana.Full Answer >
The energy-converting organelle found in plant and algae cells is called the chloroplast. Only some plants and algae have chloroplasts.Full Answer >
The Hill Reaction takes place when chloroplasts or chloroplast fragments in light split water in the absence of carbon dioxide. This reaction occurs when electrons from water transfer to an electron acceptor, reducing the acceptor.Full Answer >
The Calvin cycle takes place in the stroma of the chloroplast. Carbon dioxide enters the stroma of the chloroplast to combine with the five-carbon compound called ribulose1, 5-Biphosphate to form two molecules of a three-carbon compound called 3-Phosphoglyceric acid. This reaction is catalyzed by an enzyme called Ribulose bi-phosphate Carboxylase.Full Answer >
