Hello today I am going to tell you about leaves and why they change colors. First I am going to tell you about chlorophyll. Chlorophyll is green color that is on leaves. When the chlorophyll is gone the leaves change different colors like orange, red, and sometimes blue.
Now I am going to tell you more about chlorophyll. If you play sports like football, soccer, or if you just play in the grass you would get something green on your clothes that is called chlorophyll. The chlorophyll usually starts fading away on the leaves in the fall. The reason why leaves fall is because of the strong wind and rain falling on the trees. Now I am going to tell you why leaves change colors. The leaves change colors because the days get shorter and there is less sunlight. Leaves need sunlight to survive. If they don't get enough sunlight they will lose there chlorophyll, change colors, and die.
This is a picture of chlorophyll.
In the picture with the trees all the green is chlorophyll. Now I am going to tell you about photosynthesis. Photosynthesis is the process in how plants get their food. Photosynthesis is when the sun hits the plants and the sun gives the plant energy.
Here is a picture that I meant to put in my blog earlier.
Sorry that picture was so funny!
