Fern spores on the underside of a frond When plants like moss first began to grow outside the water, about 540 million years ago, they needed a way to reproduce themselves that didn't depend on water so much. Some of these plants evolved to be able to produce spores. To make spores, plants [...]

Cell division The very earliest photosynthesizing plants on Earth, about 3 billion years ago, had only one cell, and they reproduced the way most one-celled creatures do, by mitosis: splitting themselves in half. By about two billion years ago, some of these cells began to split themselves in a more sophisticated way, called [...]

A moss-covered rock During the Cambrian period, about 540 million years ago, some early plants evolved from earlier algae that could live on land, outside of the water. These plants were like modern moss. All of the animals were still living in the water, so on land there was only moss and mushrooms. [...]

Mushrooms growing in a field About 600 million years ago, a few eukaryote cells developed into multi-celled creatures. Some of them became animals, and some became plants, and others became mushrooms and the other funguses like yeast. So mushrooms are not either animals or plants. Mushrooms are actually more closely related to animals than [...]
