What is a genome? The genetic material of an organism or virus, the complete complement of an organism
or virus genes along with its noncoding nucleic acid sequences.

Water and the Fitness of the
Water is the substance that makes life as
we know it on Earth possible.
Why do astronomers hope to find evidence of
water on newly discovered planets?
Life on Earth began in water and evolved
The Chemical Context of Life
But I Thought this was Biology
Well it is, but:
Nature is not neatly packaged into the
individual life sciences.
Organisms and the world they live in are
natural systems to which the basic
concepts of chemistry an
Membrane Structure and Function
The plasma membrane separates the
living cell from its nonliving
Like other membranes, the plasma
membrane is selectively permeable,
allowing some substances to cross more
easily than others.
The main macromol

Diversity of Life
(aka Organic Chemistry)
Cells are 70-95% water, the rest consists mostly of
Living organisms consist mostly of carbon-based
Proteins, DNA, carbohydrate
Cells join smaller organic molecules together
to form larger molecules.
These larger molecules, macromolecules,
may be composed of thousands of atoms and
weigh over 100,000 daltons.
The four major classes of macrom

Cell Phones off/silenced
Computers can be used
if used properly
The living cell is a miniature chemical
factory where thousands of reactions
The cell extracts energy and applies
energy to perform work
Some organisms even convert energy to
light, as in bioluminescence
Overview: The Fundamental
Units of Life
All organisms are made of cells
The cell is the simplest collection of matter
that can be alive
Cell structure is correlated to cellular function
All cells are related by their descent from ea
Overview: Life Is Work
Living cells require energy from outside sources
Some animals, such as the chimpanzee, obtain
energy by eating plants, and some animals feed
on other organisms that eat plants
Humans depend on other
