Question

reflection question: explain the relationship between photosynthesis and cellular respiration. be sure to include the main purpose of both and where they occur inside the cell.
humans and plants
humans need plants. all animals do. humanitys relationship with plants has actually made it possible for us to have a civilization. before we had cities, humans went around in little packs and were hunter - gatherers. we ate rats, birds, berries, and whatever food we could find. it wasnt very efficient. one day someone had the bright idea to plant the plants we like to eat. when humans did that, they were able to stay in one place full time. then came the cities and a huge system of agriculture to support millions of people.
big time farming
as time has passed, we have taken farming to new levels. we have manipulated species to create big apples and large ears of corn. the plants would never have done it in the wild. it took man to change the plants. we are also moving toward the genetic alteration of plants. were trying to make plants that are resistant to disease and bugs. these stronger plants will allow our crops to give us more food from the same amount of space.

Explanation:

Photosynthesis occurs in chloroplasts. Its purpose is to convert light energy into chemical energy (glucose) using carbon dioxide and water. Cellular respiration occurs in mitochondria. Its purpose is to break down glucose (and other organic molecules) to release energy (ATP) for the cell's activities, using oxygen and producing carbon dioxide and water. They are related as the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice - versa (the carbon dioxide and water from cellular respiration can be used in photosynthesis).

Answer:

Photosynthesis occurs in chloroplasts. It converts light energy to chemical energy (glucose) with reactants \(CO_2\) and \(H_2O\). Cellular respiration occurs in mitochondria. It breaks down glucose (and other molecules) to release ATP, using \(O_2\) and producing \(CO_2\) and \(H_2O\). They are interdependent as products of one are reactants of the other.
