Green Thumb

A tiny seed that fits in the palm of your hand holds the blueprint for all the characteristics of a plant or very large tree. How does this process begin? What are some of the first characteristics to become visible? What do these characteristics tell us about what type of plant the seed will become? This activity will explore some of the first visible traits of a seedling and what they reveal about the plant.
