All accepted information can be
derived only from carefully documented and controlled
observations or experiments.
Source of information.
Only tangible phenomena and objects are studied, such as heat, plants, minerals, and weather.
. Phenomena that can be studied
Physical forces that control the
world are constant through time and are the same everywhere
. Constancy and universality
The fundamental basis of the scientific method
is skepticism, the principle of never being certain of a
conclusion, of always being willing to consider new
evidence. No matter how much evidence there is for or
against a theory, it does no harm to keep a bit of doubt in
our minds and to be willing to consider more evidence
Basis
All the principles you learn in your chemistry or
physics classes are completely valid for plants
Plant metabolism is based on the principles of chemistry
and physics.
As plants make copies of their genes during reproduction,
accidental changes (mutations) occasionally occur, and
this causes the affected gene and its information to
change
Genes, and the information the contain, change
Because an individual obtains its
genes from its parents, the information it uses to control
its metabolism is similar to the information its parent
had used; thus, offspring and parents resemble each
other.
Plants reproduce, passing their genes and information on
to their descendants.
Plants must
be adapted to the conditions in the area where they live.
If they are not adapted to that area’s conditions, they
grow and reproduce poorly or die prematurely
Plants must survive in their own environment
The structure
and metabolism of one part have some impact on the
rest of the plant
Plants are highly intergrated organisms.
Be careful to consider
differences between an individual plant and that plant’s
species (the group made up of all similar plants)
An individual plant is the temporary result of the interaction
of genes and environment
Assuming that
plants have human characters such as thought and decision-making
capacity
anthropomorphism
assuming that processes
or structures have a purpose
teleology
