Ventricular septal defect (VSD), atrial septal defects, and tetralogy of Fallot are the most common congenital heart defects seen in the VACTERL association. Less common defects in the association are truncus arteriosus and transposition of the great arteries.
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.Structure of a mesophyll cell.hloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.

Detail of Virginia chain fern. In most plants, photosynthesis occurs in special cells known as chloroplasts. The green hue we see in plants is the result of tiny grains of green pigment (light-absorbing molecules) inside the chloroplasts. These pigments are commonly known as chlorophyll (chloro=green; phyll=leaf).
