Because of what's in the cells of the plant: Chlorophyll.
During autumn, leaves change color due to a decrease in chlorophyll production, revealing other pigments like carotenoids and anthocyanins.
Leaves change color in autumn due to a decrease in chlorophyll production, which masks the green pigment and allows other pigments such as carotenoids (yellow and orange) and anthocyanins (red and purple) to become visible. This change in pigments is triggered by the shorter days and cooler temperatures, signaling the tree to prepare for winter and eventually shed its leaves.
it makes it turn the color because it depends on the tempeture
During the fall season, leaves change color because the green chlorophyll in the leaves breaks down and reveals other pigments, such as reds, oranges, and yellows. This change in pigments makes the leaves appear brighter and more colorful.
The change in color of leaves is due to the decreasing levels of chlorophyll, the pigment responsible for their green color, as a result of shorter days and cooler temperatures. This reduction in chlorophyll reveals other pigments in the leaves, such as carotenoids and anthocyanins, causing the leaves to change colors.
In fall, the rugged brown leaves come out.
formed a hypothesis
chemical
They need to save up their energy,so they lose chlorophyll(what makes them green) so they won't need to use energy. Now,chlorophyll is what makes food. No food, No leaves. They drop!
the weather
Chlorophyll is the pigment that makes the leaves of plants green in color. It plays a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy to produce their food.
During photosynthesis there is the process where chlorophyll makes the leaves turn green. As fall comes the trees stop growing and this makes the process to stop. So when chlorophyll stops running through the leaves, they start to turn different colors. Than by winter all the leaves fall off and in spring they grow back again
