Science Kids: All About Photosynthesis

The video tutorial explains how all living things need food to survive, focusing on how humans and plants obtain energy. It introduces photosynthesis, the process by which plants make their own food using carbon dioxide, water, and sunlight. The video details the roles of each ingredient in photosynthesis, including how plants absorb CO2 through stomata and water through roots, transported by xylem. It also covers how chlorophyll in chloroplasts captures sunlight to produce glucose and oxygen. The tutorial includes interactive questions to reinforce learning.
