Plant Parts: Leaves

The video explores how tree views change from June to October due to leaf color changes, particularly in New England. It highlights the diversity of leaves in terms of shapes and sizes and their crucial role in photosynthesis. The process of photosynthesis, occurring in chloroplasts, is explained, emphasizing the role of chlorophyll in capturing sunlight and producing oxygen and sugars. The video also touches on why most leaves are green and how this changes with seasons.

What causes the change in leaf color from green to brilliant hues in autumn?

• They provide shade

• They are the main food-making factories

• They help in pollination

• They store water

What is the role of chlorophyll in photosynthesis?
