Gymnosperms, Angiosperms and Plant Life Cycles
StemPy LabSeed plants with naked and with enclosed seeds, double fertilisation, and the three patterns of life cycle that link the haploid and diploid generations.

Bryophytes and Pteridophytes
The amphibians of the plant kingdom, the liverworts and mosses, and the first plants with vascular tissue, the pteridophytes, with their spores, prothalli and the first step towards seeds.

Classifying Plants and the Algae
How plants are classified, from artificial systems to phylogeny, and the algae: their features, their reproduction, and the green, brown and red algae.

Plants, Animals and the Borderline Forms
The two big kingdoms are the ones you know best. In this course we state what makes a plant a plant and an animal an animal. Then we go to the edge of life: the viruses, which can be crystallised like a salt, the viroids, the prions, and the lichens, in which an alga and a fungus live as one body.

The Protists and the Fungi
Some single cells make their own food in sunlight, and some hunt for it. A mushroom looks like a plant and has no chlorophyll. In this course we study the single-celled eukaryotes of kingdom Protista and the threads of kingdom Fungi. We see how they feed, how they reproduce, how they make us ill and how they help us.

The Five Kingdoms and the Bacteria
For a long time every living thing was either a plant or an animal. Then biologists looked at the cells, and the old order broke. In this course we see why two kingdoms were not enough, how Whittaker built five, and what makes a bacterium different from every other cell. We study the shapes of bacteria, the archaebacteria, the cyanobacteria and the bacteria that help us or harm us.

Taxonomic Categories and Taxonomical Aids
A lion, a tiger and a cat look alike in many ways, and a dog is a little different. How does a biologist put this in order? In this course we climb the ranks from species to kingdom. Then we visit the tools of a taxonomist: the herbarium, the botanical garden, the museum, the zoo, and the key that finds a name step by step.

Diversity and the Naming of Organisms
Tulsi in one language is holy basil in another, and a silverfish is not a fish at all. With millions of kinds of organisms, common names cannot work. In this course we see how many kinds of life we know, we learn the rules of the scientific name, and we follow the four steps that a biologist takes from a new organism to its place in a group.

What Is Living?
A dog is alive and a stone is not. That is easy. But a mule cannot reproduce, and a salt crystal does grow. In this course we study growth, reproduction, metabolism, cells and the response to the surroundings. We find which of them is true of every living thing, and which has exceptions.
