Intro Flashcards
Give 2 examples of an evolutionary pattern
Homologous & convergent
Dr. Ferenc A. de Szalay’s research interests include:
Aquatic invertebrate and plant communities
- Riparian wetlands
- great lakes coastal wetlands
Dr. Ferenc A. de Szalay is a what?
Wetland Ecologist & instructor at Kent State University
Who coined the terms: “ecology” “Darwinism” “ontogeny recapitulates Phylogeny”
Ernest Haeckel
Note: he made gorgeous pictures of the species he encountered:
Art Forms in Nature. 1904.
What is a eukaryote?
any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate system of division by mitosis or meiosis, characteristic of all life forms except bacteria, blue-green algae, and other primitive microorganisms.
What is a prokaryote?
any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.
The cell wall of a plant is made of what?
cellulose
The cell wall of a fungi is made of what?
chitin
The cell wall of an animal is made of what?
They don’t have a cell wall, instead they have a flexible cell membrane.
What is a heterotroph?
An organism that derives energy from external sources.
They don’t use photosynthesis.
What is an invertebrate?
a Eukaryotic, unicellular or multi-cellular hetertroph that lacks a cell wall & vertebrae
What are protists?
eukaryotic, unicellular or colonial organism
What is a Metazoan?
a eukaryotic, multicellular animal
Note: “true invertebrates”
Who said: “Quite simply, the terrestrial world is turned by insects and a few other invertebrate groups. The living world would probably survive the demise of all vertebrates, in greatly altered form of course, but life on land and sea would collapse down to a few simple plants and microorganisms without invertebrates.”
E.O. Wilson
Harvard University
What is a niche?
A niche depends on what an organism does. “it’s profession”
