BIOL 420: SURVEY OF THE PLANT KINGDOM
Lecture 1: Introduction
Remember that BIOL 301 is a prerequisite for this class.
Note: references to the textbook are 6th edition first, followed by 7th, then 8th edition, e.g.

Lecture 11- 2013
Dinophyta or Dinoflagellates
- mostly unicellular
- important components of phytoplankton, but also found in fresh water
- unique flagella arrangement:
- two flagella beating within grooves
- one groove like belt around
Lecture 13 - 2013
Chlorophyta continued: 3. Class Charophyceae
fig 17-36 and 17-37
- often highly differentiated, look like plants
- Chara is also called stonewort because some have calcified cell walls, other name is
- in fact, these are the cl
Lecture 9 - 2013
The life cycle of fungi.
compare this to the ones on animals and Protista and Plantae
fungi: see figure in appendix
- Two haploid hyphal cells of opposite mating type (+/-) fuse and form one cell. In other life
cycles, this is associated
Lecture 6 - 2013
Intro: serial endosymbiotic theory
Origin of the eukaryotic cell
transition from prokaryota to eukaryota;
how did eukaryotic cell develop?
first: important differences again:
Lecture 2 - 2013
- plethora of organisms out there
- human need for finding a secure position in a chaotic world involves the desire to
name and classify things, organisms and people.
- since several hundred years, naturalists were
Lecture 10 -
the kingdom protista
comprises eukaryotic organisms that cannot be grouped with animalia, plantae and fungi;
'membership by exclusion from other kingdoms'
Lecture 12 - 2013
Brown Algae: LIFE CYCLES
- alternation of generations to various degrees
- series of progressive reduction of gametophyte (GP) within brown algae
2 examples in textbook; Laminaria, a kelp, and the rockweed Fucus:
here, we see different d
I added two articles on the symbiotic relationship of corals and algae
and how important this is for the survival of coral reefs which are
critically important for regeneration of marine organisms that are
important for human consumption.
Lecture 5 (and 6) 2013
MAJOR GROUPS OF ORGANISMS
Fungi: see Lecture 4
12 phyla (7th edition textbook: 10 phyla)
examples: mosses, ferns, horsetails, flowering plants, duckweed - redwood tree

Some distinguishing features of
Lecture 4 - 2013
Molecular Systematics continued
Phylogeny based on Protein Sequence Data
- cytochrome c has been frequently used to establish the phylogenetic relationship
among a range of distantly related species.
- functions in respiratory chain
Lecture 3 - 2013
Previously, systematics was very much subject to an individual scientist's
intuition to determine certain criteria used to construct phylogenetic trees. In
1956, Willi Hennig developed cladistics, a methodology that is more obj
