What is cellular respiration? Cellular respiration is a catabolic process by which cells of living organisms obtain the energy available in sugars. Cells take sugars into the cytoplasm, and after a complex series of metabolic processes, the sugar is broken down to release energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, sugar and oxygen gas are converted to carbon dioxide and water. The process gives off energy in the form of heat and the phosphorylation of ADP to produce ATP. The carbon dioxide given off can be used by photosynthesizing cells to form new carbohydrates.

The potential energy in ATP is used to power almost all cellular activities. Cells use the energy in ATP to grow, rebuild, repair, reproduce, and react to the external environment. Cellular respiration occurs constantly within an organism and if it ceases, the cell and ultimately the organism dies. What is photosynthesis? Photosynthesis is the process by which green plants use their (mostly) green pigment chlorophyll,sunlight, water and Co2 to make sugar and give off oxygen as a by-product. In photosynthesis, plants obtain energy from sunlight and use it to convert atmospheric cO2 into energy-rich carbohydrates. The process begins with the small pores on the underside of the plant's leaves called stomata opening to allow carbon dioxide to enter its cells. Inside organelles within plants and algae cells called chloroplasts which contain a diverse array of (mostly green) pigments, carbon dioxide combines with water from the plant's roots and with energy supplied by the sun forms glucose and oxygen. Plants, algae, and some bacteria can use light energy to turn carbon dioxide and water into simple sugars through the process of photosynthesis. These sugars can act as “building blocks” for the synthesis of other organic
