How did plants impact the columbian exchange?

Plants played a crucial role in the Columbian Exchange by facilitating the transfer of agricultural products between the Old World and the New World. Crops like potatoes, tomatoes, and maize were introduced to Europe, which significantly improved diets and agricultural practices, leading to population growth. Conversely, Old World crops such as wheat, rice, and sugarcane were brought to the Americas, transforming local economies and farming methods. This exchange not only altered global food systems but also had lasting cultural and economic impacts on societies worldwide.
