Coconut sprout is when a small baby plant starts growing out of a coconut. It happens when a coconut falls from a tree and starts to rot on the ground. Inside the coconut, there is a little bit of water that helps the plant grow.
As the plant grows, it first creates a stem that helps it stand upright and then starts growing roots into the ground. The leaves of the plant grow from the stem and slowly start turning green.
People can sometimes cut the sprout off of the coconut and use it for cooking and eating, especially in certain countries where coconut is used a lot in meals. However, it's important to note that coconut sprouts are not commonly found in grocery stores and can be difficult to find.
