Summary: Biology 2004
Microbes were the first forms of life on earth, and are major, often dominating
components of the modern biosphere. They interact with animals and plants as food, as
symbionts and as parasites and pathogens.
Plants are integral to the evolution of life on land. They are responsible, along with algae,
for changing the atmospheric oxygen concentration, which lead to further diversification
of the organisms living at the time. Plants also form the basis of terrestrial food chains,
and humans rely on 5 main crops in our diet.
This course is intended to introduce you to the main groups of plants and microbial life on
earth, based on our modern understanding of their evolution, taxonomy and fundamental
biology. This course is intended as a grounding for students interested in disciplines
including cell biology, ecology, environmental sciences, evolution, marine biology,
microbiology and oceanography.
