A Focus of an earthquake is the location where the earthquake begins. The ground ruptures at this spot, then seismic waves radiate outward in all directions. At this focus point, the release of energy due to faulting actually occurs during an earthquake. The point directly above the focus on the surface is called Epicenter. The focus is also called as Hypocenter as it is the synonym of the focus.

While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this. In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize. They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
