The Evolution of Cells and Early Plants
The evolution of cells involved different kinds of bacteria combining to create the cells of plants, fungi, and animals. The first land plants evolved from green algae around 480 million years ago and developed a root system with the help of fungi around 50 million years later.

The host cell evolved the ability to break down other cells and utilize their functions such as using oxygen to break down food.

Summary
The host cell evolved the ability to break down other cells and utilize their functions such as using oxygen to break down food. The magma from the deep Earth created plates that solidified, crashed together, and formed small continents.

Summary
The transcript explores the evolution of life and how bacterial cells develop the mitochondria, which burn oxygen to supply the body with energy. It highlights the long period of walking until reaching 600 million years ago, where multicellular organisms begin to evolve.

480 million years ago, the first land plants evolved from green algae and colonized the edges of the continents with the help of fungi, forming a primitive root system that allowed them to obtain minerals from rocks.

Summary
480 million years ago, the first land plants evolved from green algae and colonized the edges of the continents with the help of fungi, forming a primitive root system that allowed them to obtain minerals from rocks. Mosses, liverworts, and hornworts were some of the earliest examples, and they were accompanied by millipedes and spiders in their new environment.

The creation of lignin, which forms wood, became very important as plants began to populate the Earth.
34:59 - 36:23 (01:24)
Summary
The creation of lignin, which forms wood, became very important as plants began to populate the Earth. If wood doesn't decompose, it can build up and ultimately result in a snowball earth, wiping out multicellular life and evolutionary innovation.
