The sugar can … • Chloroplast is a double membrane bound plastid type organelle, which contains thylakoids, stroma, circular DNA, ribosomes and lipid droplets, whereas the chlorophyll is only a molecule. , the lamellae) and the stroma, a colourless matrix in which the lamellae are embedded. 4 Stromal thylakoid Describe what can happen to the three-carbon molecules made in the Calvin cycle. Het stroma is de grondvloeistof van een chloroplast. Function. The stroma has many disc-type parts called thylakoid. Chloroplasts are green colour and disc shape organelles. Mitochondria and Chloroplast have two chambers inside them which is the matrix and the cristae in mitochondria, stroma, and thylakoids in a chloroplast. They are the sites of the light-dependent reaction of photosynthesis. ta (-mə-tə) 1. 8 Plastoglobulus The light independent phase of photosynthesis occurs in the stroma region of the chloroplast. The stroma also contains ribosomes and DNA molecules (i.e., 80 DNA molecules per chloroplast per cell of Chlamydomonas; 20 to 40 DNA molecules per chloroplast per cell of the leaf of maize), both of which are involved in the Photosynthesis is a process in which plant produces food in the presence of sunlight. These grana resemble a stack of thylakoid "coins" or "disks." 5. Stroma - The stroma is the liquid inside the chloroplast where other structures such as the thylakoids float. The stroma also contains ribosomes and DNA molecules (i.e., 80 DNA molecules per chloroplast per cell of Chlamydomonas; 20 to 40 DNA molecules per chloroplast per cell of the leaf of maize), both of which are involved in the synthesis of some of the structural proteins of the chloroplast. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The colorless semiliquid material inside a chloroplast, in which the thylakoid membranes are embedded and where the dark reactions of photosynthesis occur. Chloroplasts move by chloroplast actin (cp-actin) filaments that must be polymerized by Chloroplast Unusual Positioning1 (CHUP1) at the front side of moving chloroplast. A chloroplast is a type of organelle known as a plastid, characterized by its two membranes and a high concentration of chlorophyll. In addition to enzymes, two basic types of molecules - pigments and electron carriers – are key players in this process and are also found in the thylakoid membranes.
