Photo Synthesis would be as plants grow from the sun or gain energy from the sun, where as Cellular Respiration is when cells divide into two or more. (I believe)
The right answer is the lysosome
The lysosome is a eukaryotic cell organelle.
The lysosome contains hydrolases, enzymes intended for the degradation of intracellular molecules. They are only active at acidic pH, hence the lowering of the pH in the vesicle.
The lysosome has a cellular garbage function, where the non-functional or undesired molecules are removed by digestion.
