Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane folded into disc-shaped sacs called thylakoids. Like mitochondria, chloroplasts have a double-membrane envelope, called the chloroplast envelope, but unlike mitochondria, chloroplasts also have internal membrane structures called thylakoids. Each of the envelope membranes is a lipid bilayer that is between 6 and 8 nm thick. smooth. [2] Over millions of years the endosymbiotic cyanobacterium evolved structurally and functionally, retaining its own DNA and the ability to divide by binary fission (not mitotically) but giving up its autonomy by the transfer of some of its genes to the nuclear genome.

Prokaryotic and eukaryotic cells. A steep H+ gradient is formed, which allows chemiosmosis to occur, where the thylakoid, transmenbrane ATP-synthase serves a dual function as a "gate" or channel for H+ ions and a catalytic site for the formation of ATP from ADP + a PO43− ion. 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. Part of the photosynthesis reactions occur in an internal membrane within the organelle. Oxygen.
