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.
  mitochondria and chloroplasts are two very different organelles with different functions.   the function of chloroplasts is basically to make food, by trapping light â¦ energy to convert water and carbon dioxide to form oxygen and glucose.this process is called photosynthesis.  the function of the mitochondria is to provide energy for the cell's use, by extracting the energy from the glucose molecules, and storing them in adenosine tri-phosphate(ATP) molecules. The ATP molecules will then diffuse out of the mitochondrion for the cell's use.his process is called photosynthesis.   the function of the mitochondria is to provide energy for the cell's use, by extracting the energy from the glucose molecules, and storing them in adenosine tri-phosphate(ATP) molecules.
