Leaf Anatomy and Photosynthesis Concepts

Ashley introduces the concept of leaves, explaining their role in photosynthesis and how to identify them. The video explores why leaves change color in different seasons, focusing on chlorophyll and other pigments. An interactive leaf identification segment is included, followed by a hands-on leaf rubbing activity.
