4.1 Cell Communication continued

Neurotransmitters, Serotonin, and Paracrine Signaling 


Today's Learning Objective(s):

·  Describe the ways that cells can communicate with one another.

·  Explain how cells communicate with one another over short and long distances

#

Tasks:

1

Game of Telephone

You are to get a message from the teacher. They are to relay the message through the class

2

OK GO Rube Goldberg Machine

You are to watch the video. How is the Rube Goldberg machine functioning similar to the game telephone? Where might there have been failure points in the machine before the perfect run? 



 

3

Notes > Immune System and Cell Communication

“What ways do the cells of the immune system communicate with each other?” Focus on the immune response. How are the actions of the cells like the game telephone and a Rube Goldberg machine?

 

4

T-Cell Immune Response

You are to receive an example T cell response. You are to review the schematic for familiar cell structures and functions. Then, let’s connect it to the cell communication and signaling in unit 4.

 

5

Card Sort – Types of Cell Signaling

Groups, you are to sort the scenarios into the four types of cell signaling.

 

6

Notes > Cell Communication

Let’s go over the details.

 

7

Poster: Ligands

You are assigned a ligand (signal molecule). You will

research its properties, identify the signaling mechanism and range, and produce a simple flow chart showing how the signal is produced, transmitted, received, and the cellular response. Due end of the week.
