Cellular respiration and photosynthesis are important topics in Year 10 Biology. However, many students have some misunderstandings about them. Let's break it down:
Where Do They Happen?
One big confusion is about where these processes take place.
Some students believe that photosynthesis happens in the roots of the plant.
But actually, it occurs in the chloroplasts of leaf cells.
Cellular respiration happens in the mitochondria, which are present in both plant and animal cells.
Oxygen and Carbon Dioxide
Another common belief is that plants only make oxygen during the day and stop at night.
The reality is that while photosynthesis uses sunlight to produce oxygen during the day,
cellular respiration happens all the time, whether it’s light or dark.
This process uses oxygen and releases carbon dioxide.
Storing Energy
There’s also a misunderstanding about how energy is stored and used in plants.
Many people think that photosynthesis only makes glucose.
But it actually also creates starch for energy storage.
On the other hand, cellular respiration not only breaks down glucose,
but it can also use other types of molecules, like fats and proteins, for energy.
How They Work Together
Finally, some people don’t see how these two processes depend on each other.
It's important to remember that the products of photosynthesis (glucose and oxygen) are what cellular respiration needs to work.
This amazing cycle is vital for life on Earth!
By understanding these key points, you can see how cellular respiration and photosynthesis work hand-in-hand in nature!
