1st talk: I've always wondered, why are plants and always green in the summer and change their colors in the fall?
1st talk; See, we plants go through a process called photosynthesis. During summer, where there is plenty of sunlight, we make lots of chlorophyll from chloroplasts. ( a pigment found in all green plants ) And in fall, ( not a lot of sunlight ) we don't produce a lot of chlorophyll, which causes us to change colors.
2nd talk :I see!
2nd talk :We collect energy from the sun and use carbon dioxide and water to produce sugars that we need! That is callled photosynthesis, remember? The scientific equation for photosynthesis is Carbon Dioxide+ Water+Sunlight -> Glucose+ Oxygen.
1st talk : So how do plants obtain food from sunlight?? 3rd Talk: Oh yeah!
2nd talk: First of all, in the cytoplasm, the glucose or sugars are broken down into smaller molecules. In this process, no oxygen is involved and a small amount of energy is relased.
1st talk: I am confused? How are the sugars turned into energy?
1st Talk: In stage 2 of converting the sugars into energy or ATP, in the mitochondria, small molecules are broken down into smaller molecules. It requires energy to complete but gives even more energy to use. This results in C02, H20, no energy. That’s is called cellular respiration.
Hey, no problem bro!😉
I get it now! I now understand why plants and leaves change colors in the fall and how they use the energy from the sun to convert that energy for themselves! Thanks so much!
