Maternal and fetal tissues form two units that are closely bound together at the placental level. Quiz. The fetal part of the placenta is made up of the chorionic plate with its placental villi, the cytotrophoblast layer and the intervillous spaces.
1 , which performs the function of photosynthesis. 2  Chloroplasts are double-membrane-bound, like mitochondria. 3  Also like mitochondria, their inner membrane is very complicated. 4  In fact, it's formed into many thylakoid structures which perform the same function performed by the thylakoids in prokaryotic cells.
Prokaryotes get energy by performing chemical reactions within the cell. All organisms are able to do glycolysis, which splits a molecule of glucose in half and releases a little bit of energy in the form of ATP(adenosine triphosphate). Some prokaryotes are also capable of additional reactions that produce more energy, similar to what happens in the mitochondria of eukaryotes. Aerobic prokaryotes contain the enzymes necessary to break down the pyruvate to carbon dioxide and produce a little more ATP, along with some electron carrier molecules like NADH and FADH2.
