Leaves contain chlorophyll, a green pigment that plays a crucial role in photosynthesis by absorbing light energy, primarily from the sun. This process enables plants to convert carbon dioxide and water into glucose and oxygen. In addition to chlorophyll, leaves may contain other chemicals such as carotenoids and anthocyanins, which contribute to their color and can have various protective functions.
The term "red leaf" typically refers to the color of a leaf, which can indicate a change in pigmentation due to various factors, such as environmental conditions or seasonal changes. This process often involves the breakdown of chlorophyll and the production of anthocyanins, which is a chemical change. Therefore, the transformation of a green leaf to a red leaf can be considered a chemical change due to the alteration of its chemical composition.
Crushing a leaf is a physical change, not a chemical change because the chemical composition of the leaf remains the same before and after crushing. However, if the crushing process causes the leaf to release certain chemicals due to breaking of cell walls, then it can result in a chemical change.
The decay of organic matter such as leaves is a chemical change.
The color change in a leaf typically indicates a chemical change when it results from the breakdown of chlorophyll and the revealing of other pigments, such as carotenoids and anthocyanins, as the plant prepares for winter. This process involves biochemical reactions that alter the pigments present in the leaf. Conversely, a physical change may be indicated if the color change is due to external factors like exposure to light or temperature without altering the leaf's chemical composition.
When a leaf changes color in the fall due to the breakdown of chlorophyll molecules, it is undergoing a chemical change. This change is triggered by environmental factors such as temperature and light, leading to the production of new pigments like anthocyanins that create the vibrant colors we see in autumn.
Because the leaf is not burning.
It is a chemical change, a degradation of the compounds from the leaf.
Chemical. It has to do with the closing of the part that connects the leaf to the tree and the lack of nutrients causes the leaf to turn colours.

It's called Chlorophyll, it makes the leaf green and helps with photosynthesis.
Agent Orange was the toxic, leaf-killing chemical sprayed over Vietnam.
