Laboratories

1) Laboratory sessions begin next Monday (Sept.

20). Please bring your student card (with WHMISsticker) to the first session. If you do not have a

sticker, please attend a WHMIS training session

before your first laboratory session.

2) You will need a laboratory manual, a dissection

kit, lab goggles, a lab coat, and plain paper for

drawing diagrams.

3) The laboratory part of the course accounts for35% of the final grade. This mark is based on

laboratory assignments and quizzes, and a test at

the end of the term.


5/22

Lab exam will be comprehensive and willcover all of the material learned in the labs

bell ringer slide show format

Will need to identify organisms, namestructures and their functions, and knowaspects of life history

Make detailed diagrams of organisms seenunder the microscope, consider taking photosof dissections

Lab exam


6/22

What is zoology?

Study of animal biology Covers aspects of animal physiology,

ecology, behaviour, evolution, genetics, and

phylogeny.

What are animals?

Eukaryotic organisms that depend on eating

other organisms for nutrition


7/22

Topics for the remainder of course

1. Protista

2. Radiates

3. Acoelomates

4. Pseudocoelomates

5. Segmented worms


8/22

Topics

6. Arthropoda

7. Mollusca

8. Echinodermata

9. Chordata


9/22

Our exploration of zoology will be guided by

a number ofthemes:

Phylogeny and evolutionary relationships

Body plan and organization:

-Unicellular? multicellular?

-Radial/ bilateral symmetry?

-Support

-Body cavity: acoelomate? coelomate?


10/22

Themes:

Habitat: aquatic: marine? freshwater?

terrestrial: arid? tropical?

freeliving or parasitic?

Life cycle:

Sexual/asexual reproduction? Life stages


11/22

Gas exchange Nutrition

-source, handing, digestion

Excretion/ Osmoregulation

Locomotion

-sessile/ motile

Sensory

Themes:


12/22

Classification and systematics

We need a way to categorize and

classify organisms

Oldest system: plant or animal


13/22

Classification vs. systematics

Classification is the assignment of

organisms to categories based oncommon characteristics

Old way of categorizing animals

Systematics assigns organisms toclasses based on shared evolutionary

descent

N

ewer way that recognizes the importanceof evolutionary relationships


14/22

Basis for categorization

Comparative morphology: shapes of

bones, cells, tissues, embryonicdevelopment

Comparative biochemistry: metabolicpathways, proteins and DNA sequences

Comparative cytology: number andshape of chromosomes


15/22

The goal of systematics is to come upwith monophyletic groups (clades):

taxonomic groupings that include all thedescendants of a common ancestor


16/22

Classification

7 formal groups for all organisms


17/22

Classification


Kingdom

Phylum

Class

Order

Family

Genus

Species


18/22

Classification


Kingdom Animalia

Phylum Chordata

Class Mammalia

Order Carnivora

Family Canidae

Genus Canis

Species familiaris


19/22

Five kingdom system

Monera (bacteria) lack a nucleus

(prokaryotes)

Protista unicellular eukaryotes

Fungi

feed by absorption includes molds and

yeasts

Plantae multicellular

photosynthetic

Animalia most ingest food

parasitic exceptions


20/22

Three domain system

Newer than the five kingdom system

Based on genetic information

Recognizes three domains of life:

Bacteria,Archaea,Eucarya

Eucarya includes plants, animals, fungi

and different kinds of protists


21/22

Three domain system


22/22

Next lecture: PROTISTA- chapter 11

Origins

Diversity

Locomotion
