Compare and contrast photosynthesis and respiration Introduction: All life depends on two chemical reactions; photosynthesis and respiration. Respiration is the process by which cells convert food into energy (there are two types of respiration aerobic and anaerobic). Photosynthesis is the product of organic compounds from inorganic molecules using light energy trapped by chlorophyll. In my essay I will compare and contrast photosynthesis and respiration. At the start of my essay I will start by discussing the gas exchange in both reactions and explain different types of cells and explain why they are important. Next, I will discuss the reactions and products of the chemical reactions. Finally, I will discuss the energy transfer which takes place in the reactions. Cell parts: There are different types of cells which are adapted to do their function which is why they look and are constructed differently. Both animal and plant cells have a nucleus, they both go through cell division and both cells have the main organelles to complete protein synthesis. Plant cells can convert light and water into energy (photosynthesis), therefore animal cell cannot, a plant cell has a vacuole. This is a sac in which the cell stores water and nutrients which are later converted into energy. An animal cell has no vacuole as it does not make its own food and therefore does not need to store these nutrients in that way. A plant cell has chloroplasts. Which is needed for photosynthesis occurs, and where the pigment chlorophyll comes from, which makes the plant green. An animal cell has no chloroplasts as it does not need to make its own food. Both plant and animal cells have a nucleus. The nucleus controls the function of the cell and what takes place in it. All cells need this for control. Both plant and animal cells have a cytoplasm. The cytoplasm is what fills up the cell
