Where do autumn colors come from?
Fall leaf colors are due to plant pigments in leaves. The colored pigments are the same that produce colors in flowers and fruits. “Chlorophyll” is the pigment responsible for the green color in leaves, and for producing carbohydrates (sugars) plants need for growth.

Precipitation affects the color show – drought and excessive rainfall are both detrimental to foliage. As the amount of daylight gets shorter in the fall, chlorophyll production in leaves slows down and eventually stops.
Why do leaves fall?
The short answer is that leaves fall off trees when they aren’t doing their job any more. A leaf’s job is to turn sunlight into food for the tree. To do this, the leaf needs water. When the leaf is empty, the tree stops holding onto it and it falls to the ground, or blows away in a gust of wind.
Do leaves die when they fall?
The fall leaf life cycle starts with the end of summer and the shortening of the days. As the days get shorter, the tree does not have enough sunlight to make food for itself. Rather than struggle to make food through the winter, it shuts down. It stops producing chlorophyll and allows its fall leaves to die.
Do leaves fall in autumn?
It turns out autumnal leaf drop is a form of self-protection. While evergreen plants in cold climates have thick waxes and resins to protect their leaves from freezing and fracturing, deciduous species generally have thin leaves that are susceptible to cold temperatures.
Why do leaves fall off trees during autumn?
With temperatures falling in autumn, production of chlorophyll stops and the levels of this chemical within leaves reduces. In turn, this lets other chemicals within the leaves come to the fore. As chlorophyll reduces, it leaves an abundance of carotenes which are yellow.
Why do leaves change Colour in autumn experiment?
The Science Of Leaf Color Changes In Fall Leaves, like all green plants, contain Chlorophyll. Chlorophyll is the molecule that traps the energy of the sun and is called a photoreceptor. In this science experiment we used rubbing alcohol and two types of energy to separate the colours.
