Answer:
Carotenoids and Anthocyanins
Explanation:
During the winter the sunlight is limited for a long period of time. Plants will lose their leaves but first they will turn bright colors. The reason for this is as follows:
Plants' leaves appear green because of the presence of chlorophyll. During the fall the plants attempt to save energy. So, before they drop the leaves they first break down the chlorophyll into smaller molecules so they do not have to make the molecules from scratch all over again when spring comes. What is left behind is the Carotenoids that appear yellow and orange and Anthocyanins that appear purple.
Answer:
Please look at the explanation section
Explanation:
When the leaves begin to have a brighter color, it is because the chlorophyll begins to decompose, turning yellow or orange. As the amount of sunlight decreases, the chlorophyll pigments begin to break down. On cool nights these pigments are primarily responsible for producing a red pigment, which makes the leaves appear bright red. The low temperature and the lack of sunlight lead to a decrease in the production of chlorophyll and its subsequent decomposition, and in the absence of chlorophyll other pigments can be observed, making the leaves appear brighter.
