Unit Review & Lab: Osmosis CER & end of unit 2

 


Today's Learning Objective(s):

Review all learning objectives on the resource site.

#

Tasks:

1

Gimkit: Unit 2

Play the game.

Osmosis Lab Parts A→C & CER (part D)

 

Part D CER
This part of the lab is a group evaluation.

 

You and your lab team will create an argument about the molar concentration of the unknown solution and the water potential of the carrot cells. An argument is typically set up with the claim (in this case your suspected unknown molar concentration), evidence gathered throughout the lab experience, and reasoning (using what you’ve learned about tonicity and osmoregulation to support your claim.

 

Guiding Question:  What question were you trying to answer in the experiment?

Our Claim: What is your conclusion? You claim should address:

Unknown Solutions A→F (part A)

Water potential of the carrots (part C)

Mystery (?) solution with the carrots

 

Our Evidence: What data or information did you gather to lead you to the claim? Use your packet tables and calculations!

 

Our Justification  Reasoning: What ideas or principles from class support your claim? Does the evidence seem reasonable with what you know? Use class notes, slides, textbook, etc.

 

The score for the CER will be a group evaluation.  The presentation will be scored using the following rubric.

 

Presentations on Monday, October 27.

2.10 Origins of Cell Compartmentalization

 




Today's Learning Objective(s):

Describe the membrane bound structures of the eukaryotic cell.

Explain how internal membranes and membrane bound organelles contribute to compartmentalization of eukaryotic cell functions.

Describe similarities and/or differences in compartmentalization between prokaryotic and eukaryotic cells.

Tasks:

1

Endosymbiosis: Lynn Margulis 

 

Read the  Article  .

How is this related to cell compartmentalization?

 

Then, watch the video:

2.9 Cell Compartmentalization & Quiz

 



Today's Learning Objective(s):

Describe the membrane bound structures of the eukaryotic cell.

Explain how internal membranes and membrane bound organelles contribute to compartmentalization of eukaryotic cell functions.

Describe similarities and/or differences in compartmentalization between prokaryotic and eukaryotic cells.

Tasks:

1

Quiz: Cellular Transport

Complete each item on the quiz.

 

Paper/Pencil

Calculator Use

 

2

Where did eukaryotic cells come from?

 


YouTube

 

Then, consider the following:

 

"If you think hard enough you might begin to feel like our cells are more than just ourselves." Journey to the Microcosmos

 

What do you think Hank Green meant by this statement?

 

3

Exploring Cell Compartmentalization

 Textbook 4.3 Intro. to Eukaryotic Cells

Reread about cell compartmentalization chapter 4.3 (PG 64-65). Then answer the following questions:

1) Summarize the benefits of compartmentalization found in eukaryotic cells.

2) Examine why organelles increase cell efficiency and function

3) Explain the origins of the nucleus, chloroplast, and mitochondria of eukaryotic cells.

2.8 Mechanisms of Transport & Osmosis Lab

 


Today's Learning Objective(s):

Explain Describe the processes that allow ions and other molecules to move across membranes.

Tasks:

 

 

1

Revisit Membrane Permeability

Crash Course Biology - Let's watch a video to review topic 2.5 Membrane Transport. 

 


 

 

2

Mechanisms of Transport

From AP Biology CED:

 

"Metabolic energy (such as that from ATP) is required for active transport of molecules and ions across the membrane and to establish and maintain electrochemical gradients."

 

Use the large paper and post-it notes to classify the movement of materials with the membrane and membrane proteins as listed on the sheet.

 

3

Chart It Out: Bulk Transport

What are the different means to bulk transport material?  You are to compare the different bulk transport methods:


 exocytosis

 endocytosis

 phagocytosis

 pinocytosis

 receptor-mediated endocytosis

 

4

Lab: Osmosis Continued

 Complete the different parts of the osmosis lab:

 Part A Be sure both charts have been completed

Note: (14.) Ratioanale will be in the CER in part D

Construct the graph

Part B

Be sure to complete the table with the % change calculations

 

Part C

Calculate the water potential of the carrot

Part D

CER  - Where the claim is to be your explanations for the unknown molar concentrations A→F (part A) and Mystery? (part b).

 

From the instructions.

 

Guiding Question: What question were you trying to answer in

the experiment?

Our Claim: What is your conclusion?

Our Evidence: What data or information did you gather to lead

you to the claim?

Our Justification or Reasoning: What ideas or principles from

class supports your claims? Does the evidence seem reasonable

with what you know?
