14 I always enjoy watching leaves turn from green to red, yellow, orange, and brown. How does it all work? Any ideas yet? Keep Writing and Thinking!!! Press the space bar or click your mouse to continue!

15 During the early spring and summer, plants in our area get a lot of water through the roots. This water renews the chlorophyll (green pigment) inside the leaves of the trees. Other colors, which have been there all along become visible!

16

17 A fall with cloudy days and warm nights brings drab colors.

18

19 The color of the leaves fade as fall turns to winter, and the stems that secure them to the branches begin to loosen with the change in weather.

20

21 The variations in the color are determined by weather conditions.

22

23 And an early frost quickly ends the colorful display.

24 anthocyanin The brightest colors are seen when late summer is dry, and autumn has bright sunny days and cool (low 40's Fahrenheit) nights. Then trees make a lot of anthocyanin pigments (bright red and purple).

26 What do autumn leaves and ripening bananas have in common?

27 The green color in unripe bananas comes from chlorophyll, the same pigment that gives green leaves their color. As bananas ripen, the chlorophyll breaks down and disappears, leaving the yellow color which has been there all along. yellow color

28 The yellows and oranges of autumn leaves are also visible as their chlorophyll breaks down.
