introduction to plants Flashcards
are the sources of multiple products
of human society
PLANTS-basic human foods and have been domesticated for millennia. Plants have many cultural and other uses
is
responsible for changing global climate.
Accumulation of atmospheric CO2
is the
scientific study of plants
BOTANY - , branch of biology that deals with the study of plants, including their structure, properties, and biochemical processes. Also included are plant classification and the study of plant diseases and of interactions with the environment.
don’t produce flowers
Conifers (gymnosperms) - Gymnosperms are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The word “gymnosperm” comes from the Greek word gymnospermos, meaning “naked seeds”.
lack true leaves, stems, and roots
and neither mosses or ferns produce flowers.
Mosses - are non-flowering plants which produce spores and have stems and leaves, but don’t have true roots.
were once considered plants but
are now excluded.
FUNGI - is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Was developed by ancient Greek
philosophers. Involves developing logical explanations for
simple observations of the world.
Does not involve any verification of truth.
Only predictions were made without
experimentation. Is problematic because several conclusions
may be equally logical and plausible.
SPECULATIVE PHILOSOPHY - a philosophy professing to be founded upon intuitive or a priori insight and especially insight into the nature of the Absolute or Divine. broadly : a philosophy of the transcendent or one lacking empirical bases
slowly developed
starting before the 1400s, with four basic
tenets.
Source of information
Phenomena that can be studied
Constancy and universality
Based on skepticism
SCIENTIFIC METHOD - is the process of objectively establishing facts through testing and experimentation.
Information must be derived only from carefully
documented and controlled observations or
experiments.
Any claim must be subject to verification and proof.
SOURCE OF INFORMATION
Only tangible phenomena and observations may
be studied.
Anything that cannot be observed (or detected by
an instrument) cannot be studied.
PHENOMENA THAT CAN BE STUDIED
Physical forces that control the world are constant
through time and the same everywhere.
Experiments done at one place and time should give
the same results if carefully repeated at a different
time and place.
Constancy and universality allow us to plan future
experiments and predict what the outcome should
be.
CONTANCY AND UNIVERSATILITY
The fundamental basis of the scientific method is
skepticism.
Skepticism is never being certain of a conclusion
and of always being willing to consider new
evidence.
BASIS - SKEPTICISM
must make predictions that
can be tested.
HYPOTHESIS - is a proposed explanation for a phenomenon.
develops from a hypothesis that
consistently matches observations and
garners greater confidence.
THEORY - is a rational type of abstract thinking about a phenomenon, or the results of such thinking.
Describing, naming and
classifying plants
PLANTS TAXONOMY - is the science of naming organisms and placing them in a hierarchical structure,
