Hello my dear nature lovers, I hope you are having a beautiful weekend, and receiving this month of February with lots of positive energies... always encouraging natural contacts, as much as possible.
Today I want to talk about a very interesting topic, that although I often approached it in my school work when helping my students to create models, plates, and investigations, it is much more exciting when we know the physical context, that is, to experience a tangible process of this wonderful natural phenomenon that keeps us alive on the planet.
We are talking about photosynthesis, which we can theoretically define as follows:
It is a fundamental process for terrestrial life, since thanks to sunlight, plants obtain carbon dioxide (CO2) and expel oxygen during the day, and at night the process is the opposite, they obtain oxygen and expel carbon dioxide, thus facilitating life on Earth. This process is what provides us with the oxygen we need to breathe. We add to this definition, that thanks to sunlight, plants produce the chlorophyll that gives them their green pigmentation. In the absence of direct sunlight, plants stop producing chlorophyll and acquire a yellowish tone. Information source: Photosynthesis - Aquae Foundation
Before relating my experience with these plants that sprouted in the soil of my garden, I wanted to explain in summary form the theory of the photosynthesis process. Now I will tell you what happened with the plants in the photographs. A few weeks ago when I spent some time in my garden, I was throwing away some empty paint pots left over from the days when we painted the front of the house. Some I washed to reuse, others were damaged and I discarded them.
After washing them, I placed them on the edge of the sidewalk, with the opening facing down to drain the water.This area had some typical savanna creeping plants, and some were left under the pots.This is how several weeks went by because I really missed picking them up and putting them away beforehand.
A few days ago, when we went to clean the garden of the weeds that had grown, I lifted the pots, and found this surprise. These branches of the creeping plants stayed alive despite being covered up without sunlight, enough air, and even little water, but they totally changed their color. They went from green to almost white. Their pigmentation faded. It can also be seen that they stood upright trying to seek the sun, and not stuck to the ground like the others.
This is the physical way to explain a little of this process called photosynthesis, where the presence of the elements sun, water, oxygen, are basic for plants to produce chlorophyll and keep their green color. The pots are made of plastic, I could not tell if somehow the material allowed them to keep their humidity inside.
I hope you liked this post, thank you very much for visiting my blog. Happy saturday.
