Okay kiddo, let's talk about plants and how they evolved over time. A long, long time ago, there were no plants on Earth. But then, tiny bacteria started to grow and eventually turned into algae, which are tiny green things that can live in water.
These algae started to evolve and became more complex. They grew larger and started to develop new parts, like stems and leaves. They also started to live on land, which was a big deal. It was a tough place to live, with the sun beating down and the wind blowing hard. But these early plants were tough and they found ways to survive.
Over time, plants evolved even more. They began to grow thicker stems and develop roots that helped them stay anchored in the soil. They also started to develop flowers, which helped attract insects and other creatures to help them reproduce.
As plants continued to evolve, they became more and more diverse. Some plants grew tall and strong, like trees, while others stayed small and lived in the shadows. Some plants even evolved to live in the water, like seaweed and kelp.
So, in short, plants started as tiny algae in the water, and over millions of years, evolved to live on land, develop all sorts of different shapes and sizes, and even evolved flowers to attract creatures to help them reproduce.
