Photosynthesis & Cell Respiration

By Emily and Anna


Plants like roses need to take in certain reactants. These reactants include CO2, H2O, and energy from the sun. Water is taken in from the roots and go ups the stem. Energy is taken in from the leaves. This is where the majority of the chloroplasts are. The mitochondria holds the energy produced by the plant. Plants then release O2 and C6H12O6 (sugar). The sugar is then converted into starch.


When an animal, such as this golden retriever eats anything and digests its food it is broken down into smaller units until it becomes small enough to be used in our cells as glucose molecules. At the very same time the animal is breathing in oxygen that travels from the lungs through the bloodstream into small blood vessels until it reaches our cells. When the glucose and oxygen reaches our cells, we perform cellular respiration. This process starts in the cells’ cytoplasm and is completed in the mitochondria, In those tiny organelles, one molecule of glucose with 6 molecules of oxygen are changed into 36 molecules of ATP and the energy cells can use to get things done.

C6H12O6 (1 glucose molecule) + 6 O2 6 CO2 + 6 H2O + 36 ATP (ENERGY) carbohydrate + oxygen carbon dioxide + water + ATP energy
