“Word Map” of Four Classes of Bio-Molecules                        Unit 11

Purpose: This “word map” will help you:

1. learn the vocabulary associated with the four types of bio-molecules we study in this unit.
2. assimilate these words, associated with a particular bio-molecule, together into a coherent paragraph.
3. discuss the related and interconnected biological functions between two different types of bio-molecules in a paragraph.

Tasks:

Task 1: Select one category of bio-molecule and develop a flow chart (or concept map or word map) that depicts the interconnectedness of the group of words you selected.

Task 2: Using your “map” from Task 1, write a paragraph in which you explain the bio-molecule’s structure and function using all the vocabulary associated with that class of molecule.

Task 3:  Select a second type of bio-molecule.  Prepare a brief outline or concept map (word map) of how the second type of bio-molecule functions together with the type you selected in Task 1. 

(NOTA BENE: These outlines will serve as the basis for a short paragraph that you will write in response to a question on the exam.)
