Essay Comparing And Contrasting Photosynthesis And Respiration

They are also necessary to the energy exchange that living things need to survive.

is the process by which green plants create their own food by turning light energy into chemical energy.

After everything has been captured the first thing that happens is that inside the chloroplasts, both water and CO2 undergo a complex series of chemical reactions which is powered by the energy from the Sun, which results as sugars(glucose) and oxygen.

Considering all of this, why is this essential for life?

Just like photosynthesis, respiration requires a 2­step process.

Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need.The answer is simple, it is because we humans, and most animals need oxygen to survive, so without this process taking place, we would all be dead.Cellular respiration is the process by which by absorbing glucose and oxygen an organism releases CO2, water, and energy.Aerobic respiration and glycolysis are the two main steps responsible for completely breaking down glucose into water and carbon dioxide. Photosynthesis and Respiration By: Ramiro Garcia Through many years of school and history we have thought of Photosynthesis as two opposite things, but they actually can’t work without each other.This takes place in the plant cells that contain chlorophyll, the pigment within plant leaves that give them their green color.The chlorophyll absorbs light energy and uses it to create sugars (carbohydrates) from water (H2O) and carbon dioxide (CO2).Inside the cytoplasm glucose molecules are broken down into smaller pieces and then release energy. are complementary processes by which living things obtain needed substances.During photosynthesis there is a two­stage process.The first step is to capture the Sun’s energy, which occurs in the leaves and other green parts of the plant, and once there pigments start absorbing the light; while the same time it gets CO2 through the surrounding air, which enters the plant by going into the stomata.
