Astudent has been shrunk to a size small enough to be inserted into one of the membranebound disks of a granum. that student travels completely out of the chloroplast into the cytosol of the plant cell. how many plasma membranes in total did the student travel through?

Well,what i learned was that unlike many other  endothermic  reactions,  photosynthesis  does not absorb energy as heat. instead, during plants absorb energy from sunlight to turn carbon dioxide and water into oxygen and glucose, which is a type of sugar molecule. the energy is stored in the glucose molecules, ready to be used when needed. 

Any choices to answer ?
