One day, a mother and her daughter went to a park. The daughter was so fascinated by the trees and plants.
I know right, kid. Do you know how important they are to us? Lemme tell you why.
This place is too pretty, mommy!
These plants give us oxygen to breathe. We can't live without it. But do you know that they undergo a certain process called photosynthesis to give us what we need?
I didn't know, mommy. It sounds too complicated for me, but that's amazing! I'm kinda curious on how it works.
And then the mother tell her the step-by-step process of photosynthesis.
Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water and transport it to the leaves through the stem.
Light, water, chlorophyll, and carbon dioxide are the basic requirements for this process. First, Carbon dioxide in the atmosphere enters the plant leaf through stomata.
As sunlight falls on the leaf surface, the chlorophyll traps the energy in it. Interestingly, the green color of the leaf is also attributed to presence of chlorophyll.
It is the green pigment present in the plant leaf, kid.
Mommy, what's a chlorophyll? I never heard of that.
Then hydrogen and oxygen are produced by converting water using the energy derived from the Sun. Hydrogen is combined with carbon dioxide in order to make food for the plant, while oxygen is released through the stomata.
Similarly, even algae and bacteria use carbon dioxide and hydrogen to prepare food, while oxygen is let out as a waste product.
It's kinda confusing but I'm really amazed by the whole thing.
It's already noon when they're done talking about plants and photosynthesis.
Hope you now understand what photosynthesis is and how important it is to us.
Yup I already got it, mommy. Thank you for telling me why it was so important. From now on, I will take a good care of all the plants and trees.
