Hi my Steemit friends. Today we are going to learn that plants also need food to survive just like humans do. Humans have to eat their food that is grown in the ground and for that to happen we need plants to do the same.
Photosynthesis is the way plants use to make their own food. When humans make food they need fire, vegetables and water and other things to make their food.
The plant needs the same. They need light from the sun, water from the ground and something called carbon dioxide from the air. Plants have roots with a funny name called xylem and they absorb the water and food from the ground. There are pores in the leaves that are called stomata, and they exchange all that the plant needs. The carbon dioxide goes into the stomata with the water and there is chloroplast in there. Once all this get together photosynthesis can take place and then we see oxygen coming from the stomata to go back in the air for us to breathe.
This is also where the green colour from the leaves come from. The combination of carbon hydrates plus water, forms oxygen and glucose. Some of the glucose is used immediately for the plant the rest of is stored as starch in the plant. Everything that is stored is used when there is no sunlight as sunlight is needed to fulfil the whole process.
After all this has taken place the stomata release oxygen into the air, that makes it possible for humans to breathe the oxygen again and that is what we need to stay alive.
The plant works a lot like the body, as it takes its food from the same things we need to survive to be able to grow, and now we can have the vegetables to eat as well. The word photosynthesis has a meaning.
Photo means light in Greek and synthesis mean combining. Because of these combinations we can now grow the plant, eat it and even get oxygen from our plant to survive. There are some plants that do not use photosynthesis alone they use insects as well to stay alive.one of them.
Venus Fly Trap catches insects to eat. This is a funny plant as it has two leaves that close so that the insect is trapped and eaten. It is actually a very cool plant and I will put a picture in here for you to see how they do that.
I hope you know how photosynthesis works now and how important it is for all of us.
Thank you for reading my post, and have a wonderful day.
