The Marvelous Process of Photosynthesis in Plants

The video tutorial introduces the concept of photosynthesis, explaining how plants use sunlight, water, and carbon dioxide to produce food and oxygen. It highlights the role of chloroplasts and chlorophyll in this process and describes how plants breathe through stomata. The tutorial also touches on the importance of sunlight as a source of vitamin D and concludes with trivia about chlorophyll.

Why is sunlight important for plants?

• It is used in photosynthesis to make food.

• It helps them grow taller.

• It is a source of vitamin D.

• It keeps them warm.
