What is chlorophyllase?

Chlorophyllase is like a little cleaner that helps leaves change colors when it gets colder.

Imagine your leaf is wearing a green shirt all summer long, that’s because of something called chlorophyll, which is like the paint on the shirt. But when fall comes, the cleaner (chlorophyllase) starts working, and it slowly takes away the green paint from the shirt. That makes room for other colors like yellow and orange to show through.

Chlorophyllase does its job by breaking down chlorophyll into smaller pieces. This is kind of like when you take apart a toy, once the parts are loose, they can move around more easily. Without all that green paint holding it back, other colors in the leaf get to shine through.

This change helps trees prepare for winter. By letting go of their green shirt, leaves can send nutrients back into the tree before falling off. It’s like a little leaf cleanup crew working hard behind the scenes so the tree can rest and stay strong during the cold months.
