Survival Needs

The video tutorial explains the basic needs of plants: air, water, and sunlight. It sets up an experiment with four plants to demonstrate what happens when one of these needs is not met. The control plant receives all its needs, while the others lack sunlight, water, or carbon dioxide. After 10 days, observations show that plants without one of these essentials stop growing, highlighting the importance of each element for plant survival.
