Cellular respiration and photosynthesis are important processes we see in everyday life. They help us understand how living things function.
Breathing: Humans and animals need to breathe to create energy. When we breathe, we use oxygen and a sugar called glucose to make energy, along with carbon dioxide and water. On average, a person breathes about 12 to 20 times each minute. With each breath, we release about half a liter of carbon dioxide.
Eating Food: People burn different amounts of calories depending on their activity level. For example, when someone is resting, they use about 70 to 100 calories every hour, which also involves cellular respiration. Foods that are high in carbs, like pasta or bread, give us glucose to help with this energy-making process.
Fruit Ripening: Fruits like bananas breathe a lot after they are picked. We can measure how fast they are respiring using a carbon dioxide sensor, which shows how much energy they are using as they ripen.
Green Plants: Plants, especially those with green leaves, can perform photosynthesis. They take in sunlight, carbon dioxide, and water to make glucose and oxygen. A healthy leaf can produce about 0.5 grams of oxygen every hour when it has enough light.
Plant Growth: We can see how light affects plant growth. Studies show that plants can grow up to 30% more when they get enough sunlight.
Algae in Water: If you look at ponds, you can see green algae performing photosynthesis. Algae are really important because they produce about 83% of the oxygen on Earth, showing how crucial they are for keeping our air clean.
In summary, we can see cellular respiration and photosynthesis in our daily lives, from how we breathe and eat to how plants grow in our environment.
