What is Photosynthesis? |
What is Cellular Respiration? |
Well, for one thing, it is a long word. Photosynthesis, according to Google, is "...the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar...". Pretty simple. However, there is actually a long and amazing process that feeds these plants and other organisms.
The video below is one that I found that has a simple description. The video address is below, |
Cellular Respiration is kind of like the opposite of photosynthesis. While photosynthesis makes glucose, or sugar, cellular respiration breaks down sugar, or glucose. Also, while photosynthesis is made with carbon dioxide and water, that is the output of cellular respiration. Cellular respiration occurs in the Mitochondria. while photosynthesis occurs in the Chloroplasts.

PhotosynthesisPhotosynthesis occurs in two stages, light reactions and Calvin cycle. Photosynthesis occurs to get glucose, a form of sugar that keeps plants alive. Light Reactions is when water and light go into the Chloroplasts (See definition here). The chloroplasts contain a stack of thykaloids, to form a Granum. Chloroplasts are very good at absorbing light, except green light. That is why plants appear green. The light and H2O sent into the chloroplasts's Grana combine together to get ATP, a form of energy, NADPH, another form of energy, and Oxygen, which helps us breathe. Calvin Cycle is when Carbon Dioxide which we breathe out, combines with the ATP and NADPH to get glucose. this occurs in the chloroplasts's Stroma, a thick fluid inside the inner membrane of the chloroplast.

Cellular RespirationWhen someone hears the word respiration, they might think of how humans breathe. Cellular Respiration is not how humans breathe, but the process is similar. Photosynthesis makes glucose to help cellular respiration. In this process, Mitochondria use Glucose to make energy (ATP), carbon dioxide and water. The general equation looks like this:
C6H12O6 + 6O6 = CO2 + H2O + ATP (energy) |
ATP is important to both of these processes. In photosynthesis, the plant cell makes glucose, but also requires ATP to do so. In cellular respiration, the cell uses glucose to make ATP, which is then used to fuel the cell, make more glucose, make more ATP, and repeats the cycle over and over again.
