Biology Discussion Notes
Monday 10/6/2014
Goal for the Day
1. Understand what ecology is.
2. Be able to describe and list examples of
abiotic & biotic factors.
•
Know and understand what we didn’t know
on the test.
Question of the Day
• What are the factors that affect seed
germination?
• Think of factors that you decided to test in
your germination experiment.
Species of the Day
• Resurrection Plant Selaginella lepidophylla
• Predict whether this plant is
dead or dormant. If you
think this plant is dormant
predict how long it would
take for this plant to begin
to be active again.
Species of the Day
• Resurrection Plant - Selaginella lepidophylla
• This plant belongs to the Lycophyta and has the
oldest known lineage of any VASCULAR plant.
Being as this plant represents one of the most
primitive vascular plants, do you think this plant
has seeds or not? Explain your answer
What is Ecology?
• Ecology
– The study of interactions among organisms and
among organisms and their environment
Who came up with the term ecology?
• The term “ecology” was coined by the German
zoologist, Ernst Haeckel, in 1866 to describe
the “economies” of living forms.
What is Ecology?
– Which of the ten themes do you think will play
heavily in this chapter?
Ten Unifying Themes of Biology
1. Biological Systems – cell, tissue, organ, organ
system, organism, population, community,
ecosystem, biome, biosphere
Intro to Ecology
• Within the theme biological systems what was
the difference between an ecosystem, and the
level before/below it?
• Community-
• Ecosystem-
Biotic vs. Abiotic
• Biotic Factor–
• Abiotic Factor-
Intro to Ecology
• Which of the factors that we listed as
important for germination and early plant
growth are abiotic factors, which are
biotic?
• Which of the
factors that
we listed as
important for
germination
and early
plant growth
are abiotic
factors, which
are biotic?
Intro to Ecology
Plants Test
• If you haven’t taken the test go out to the
hallway with your study guide and take a
minute to study!
Tests & Test Corrections
• On a separate sheet of paper you will
REWRITE ENTIRE QUESTION, then write the
correct answer to this question.
• This is an assignment, and is required. If you
do not complete this assignment then you will
be tagged. Missing study guides if not turned
in tomorrow will also receive a tag!
