There wouldn’t be any forests, lawns, meadows, or flowers. That’s right, things would look very different and would be very different. You would not have any fruits or vegetables to eat or any of the animals that depend on plants for survival. In fact, life would not be possible. In this module you will learn about plants: how they grow, what they need to grow, and how they reproduce. You will also experiment with growing plants under new conditions.
