Gymnosperms and AngiospermsPlant Life Cycles and Alternation of GenerationsFreeCh 3 · 3/4

Gymnosperms, Angiosperms and Plant Life Cycles

StemPy LabStemPy Lab

Seed 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 PteridophytesFreeCh 3 · 2/4

Bryophytes and Pteridophytes

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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

StemPy LabStemPy Lab

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?

StemPy LabStemPy Lab

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.

Extra courses with a plan

These are part of our upcoming paid plans.

Plant Kingdom: Deep Dive and NEET Practice
StandardFirst lesson freeExtra course

The plant groups side by side, with their key examples, economic uses and the tricky points that exams test, worked step by step, and a full NEET-style mock exam.

Biological Classification: Three Domains, Microbes in the Laboratory and NEET Practice
StandardFirst lesson free

Two kinds of bacteria can differ from each other as much as a bacterium differs from you. How do biologists know? In this course we read three ideas that the main chapter only touches: the three domains of life, how bacteria are stained, grown and counted in a laboratory, and how a virus takes over a cell. Then we solve harder problems and take a NEET style test.

3Lessons12Problems3Python Labs
The Living World: Species, Naming Rules, Keys and NEET Practice
StandardFirst lesson free

A horse and a donkey can have a young one, the mule, and the mule cannot have young. So are the horse and the donkey one species or two? In this course we read three ideas that the main chapter only touches: what a species really is, the finer rules that give each species one name, and how a key and a DNA barcode find a name. Then we solve harder problems and take a NEET style test.
