Start from a lower magnification (5-10x) to find the focus of cells. Chloroplasts are multifunctional organelles whose morphology is affected by environmental stresses. Water diffuses into the red blood cells by osmosis, and the cells eventually burst. The electrons then enter the electron transport chain, a series of reactions that ultimately drives the phosphorylation of adenosine diphosphate (ADP) to the energy-rich storage compound ATP.
