Cell Theory, Prokaryotes and Eukaryotes
StemPy LabWhat a cell is, the cell theory and who built it, an overview of cells and their sizes and shapes, and the prokaryotic cell with its envelope, mesosomes, ribosomes and inclusion bodies.

The Cell Membrane, Wall and Endomembrane System
The fluid mosaic model of the cell membrane and how things cross it, the plant cell wall, and the endomembrane system: endoplasmic reticulum, Golgi apparatus, lysosomes and vacuoles.

Mitochondria, Plastids and the Nucleus
The organelles outside the endomembrane system: mitochondria, plastids, ribosomes, the cytoskeleton, cilia and flagella, centrosome and centrioles, microbodies, and the nucleus with its chromosomes.

Animals Without a Backbone
The non-chordate phyla, from Porifera to Hemichordata: sponges, cnidarians, comb jellies, flatworms, roundworms, annelids, arthropods, molluscs and echinoderms.

How Animals Are Classified
The features used to classify animals: levels of organisation, symmetry, germ layers, the body cavity, segmentation and the notochord, and how they sort the phyla.

Gymnosperms, Angiosperms and Plant Life Cycles
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 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.
