In fall, chlorophyll is the first pigment to disappear from dying leaves? Using what you have seen today, and specific vocabulary from the introduction, explain why some leaves turn bright colors in fall.

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.

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.

halogen, any of the six nonmetallic elements that constitute group 17 (group viia) of the periodic table. the halogen elements are fluorine (f), chlorine (cl), bromine (br), iodine (i), astatine (at), and tennessine (ts).

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
