Cold nights: low temperatures destroy chlorophyll so the green leaf fades to yellow, but if temperatures stay above freezing, anthocyanin production is enhanced and the leaves take on a red colour. Dry weather: sugars become concentrated in the leaves, more 2013-11-21 2001-10-01 2005-12-01 Repeat step (1)-(8) from Project 1, this time using leaves that have changed color. You may have to wait much longer in steps (4) and (7). There is normally much less of the other colors in the leaves compared to the green chlorophyll. PROJECT 3 - Observe how light affects color development What you need: a tree with leaves that turn red in autumn Leaves may contain many pigments, some more visible than others depending upon their quantity and location in the leaf.

In autumn, the leaves of deciduous trees change colors. This is because chlorophyll is degraded and _____ askedSep 11, 2016in Biology & Microbiologyby Spencer A) carotenoids and other pigments are still present in the leaves
Chlorophylls are degraded and flavonoids synthesized during autumn senescence of deciduous trees. There is so much chlorophyll in an active leaf that the green masks other pigment colors. Light regulates chlorophyll production, so as autumn days grow shorter, less chlorophyll is produced.
