Course description:

The course covers aspects of the biology of cells (both prokaryotic and eukaryotic) as independent entities and as parts of complex multicellular individuals.  The course material is presented in an evolutionary framework.

 

Course objectives:

(i)                  To provide an overview of cell structures and functions

(ii)                To view the cell as an open system

(iii)               To understand cellular structures and functions in the context of their evolutionary history

(iv)              To view cells as complex systems and appreciate the hierarchical nature of biological systems

(v)                To appreciate both the unifying principles and the great diversity of biological systems

 

Textbook:

“The World of the Cell” by Becker – Kleinsmith – Hardin; 7th, 6th, or 5th edition (the Solution Manual to the “The World of the Cell” by Becker – Kleinsmith – Hardin may be found helpful by some students)

- copies of each are placed on reserve in the Library

 

Lectures’ outlines:

-will be placed on Blackboard prior to each lecture

-you can print out the outline and bring it to class

-LECTURE OUTLINES ARE NOT SUFFICIENT!!!!! You still need to read the material in the textbook and take notes during lectures!

-Lectures might cover material that is not included in the Blackboard Outline or textbook; this will be indicated during the lecture. It is your responsibility to take notes. If you missed the class it is your responsibility to obtain that information from your classmates.

 

Readings:

-will be mainly directed to chapters in the Textbook

-material that is not covered in the Textbook will be clearly identified during the lecture

-you will also be responsible for sections in the Textbook that have not been thoroughly covered in the lecture; they will also be identified during the lecture

-unless indicated on Blackboard or in class, you are responsible for ALL the information covered in the textbook pages indicated (including figure legends), at the level of detail the textbook provides, even if not covered in class (where we will focus on selected topics).

-post ALL questions about course, lectures and tests on the Blackboard Discussion, so everybody can see the questions and my answers (as often students ask the same questions) 

 

Evaluation:

- 2 TESTS (see Schedule) – each testing the material covered in the previous lectures, AND a FINAL exam – testing the material covered during the entire semester

- make-up tests and final exams are offered ONLY if a written medical excuse is provided

- BOTH tests AND the final exam are required in order for the final mark to be submitted to the Registrar’s office.

- the two tests are each worth 25% and 35% of the final mark, respectively; the final exam is worth 40% of the final mark

- test and final exam formats will be discussed in class; if you miss the class, ask your classmates or post your questions on the Discussion site on Blackboard.

- the level of detail (how much emphasis on some aspects) will be mentioned during lectures; if you miss a lecture, ask your classmates or post the question on the Blackboard Discussion site

-studying for this class requires more than memorization; it requires the ability to compare, contrast, integrate
