Unit 2: Heredity
Unit Essential Question: Why is the cell considered the basic unit of structure and function in living things?
Key Learning: All living things are made of cells. Although they are small, cells are
complex structures that can regulate the chemicals that enter and exit through
their outer layer. Cells divide to
create new cells to allow organisms to develop and grow. Genetic material is contained within cells
and is passed on to future generations.
Occasionally, problems can occur during cell division, leading to
mutations. Sometimes these mutations can be beneficial to the individual or to
the species as a whole.
