Zoology Exam 1 Chapters 1, 2, & 3
What is zoology? - Answer-Study of animals
What are 6 specializations in zoology? What are 3 specializations in zoology by taxonomic categories? -
Answer-Anatomy; Form & Function; Cytology; Comparative Genomics; Ecology; Genetics; Embryology;
Histology; Parasitology
Entomology; Herpetology; Icthyology; Mammology; Ornithology; Protozology
What is organic evolution? Who was Charles Darwin? When was the Origin of Species published? -
Answer-Organic Evolution-source of animal diversity and explains relationships between animal groups
Charles Darwin-Father of Evolution; is given credit because he had a workable mechanism with it
(natural selection)
Origin of Species published 1859
Who was Carl von Linne (or Linnaeus)? What is binomial nomenclature? When was Systema Naturae
published? - Answer-Linnaeus-Father of taxonomy
Binomial nomenclature-two part naming system to classify organisms (Genus species)
Systema Naturae published 1735
What is ecology? - Answer-Interaction between organisms and environment
What are the 2 perspectives of zoology? - Answer-Evolution & Ecology
, What are cells? - Answer-Fundamental unit of life
What is the structural hierarchy from atoms to animal? (10) - Answer-Atoms; Molecule; Macromolecule;
Membrane; Organelles; Cells; Tissues; Organs; Organ System; Animal
What are 5 differences between prokaryote and eukaryote cells? - Answer-Prokaryote-No nucleus;
smaller; less complex; no organelles; RNA; no histones
Eukaryote-Nucleus; larger; more complex; organelles; DNA; has histones
What are 3 features shared by all cells? What are 3 features by all eukaryotic cells? - Answer-All Cells-
Ribosomes; Plasma Membrane; Cytoplasm
Eukaryotic Cells-Plasma Membrane; Cytoplasm; Nucleus
Why are (most) cells so small? Why is it an advantage to have a large surface area to volume ratio
(SA/V)? - Answer-To maximize surface area to volume ratio
More can be done/made; more efficient
What is the function of the plasma membrane? What is the fluid-mosaic model? What is the function of
cholesterol in cell membranes? What is the function of glycocalyx in cell membranes? - Answer-Plasma
Membrane-allows transportation in and out of cell; provides structure
Fluid-Mosaic Model-selectively permeable; picks and chooses
Cholesterol-controls fluidity
Glycocalyx-"cell coat"; cell to cell recognition
What are 4 functions of cell membranes? - Answer--Control intracellular+extracellular transport
-Provide large surface area
-Separate inside and outside of cell
-Separate cells from each other
What is zoology? - Answer-Study of animals
