SNC 2P - Biology - Cells & Organelles

Learning Goals: 

Studying cells helps us understand how organisms function.

Cellular organelles work together to carry out life functions.

Cellular processes enable organisms to meet their basic needs.

Success Criteria: 

I can…

…list out why studying cells is important.

…label organelles on a plant & animal cell diagram.

…indicate the functions of organelles.

…describe diffusion & osmosis and provide examples.

Anticipation Guide

What do you already know about tissues, organs and body systems?  Let's find out!

What Do I Know?

 

Why Should We Learn About Cells?

It allows us to

• determine how organisms function
• determine how to protect cells to prevent infection and disease
• observe cells to diagnose disease
• treat cells to heal illness
• stop harming cells through our choices and actions

 

The Cell Theory

1. All living organisms are made up of one or more cells.
2. The cell is the simplest unit that carries out the processes of life.
3. All cells come from pre-existing cells.

The history of cell theory is super wacky.  Check it out.

Cells, Cells, They're Made of Organelles...

An organelle is structure within a cell.

Organelles work together to carry out certain functions that support the life of the cell.

These functions include transporting in nutrients, taking out wastes, generating and releasing energy for cell use, making necessary substances and reproducing.

Just try to not sing along with the chorus.  I dare you.  😉

 

Cells & Organelles

All living things are made up of cells - either animal cells or plant cells, depending on the organism. All cells are made up of organelles.  

Animal Cell

 

Plant Cell

An organelle is a structure within a cell.  Organelles work together to carry out all the functions that support the life of the cell.

These functions include:

• bringing in nutrients
• removing wastes
• creating and providing energy for the cell to use
• making substances required by the cell
• reproducing
  

Let's make like an organelle and do some work.

 

SNC 2P - Biology - Microscope

How do scientists see cells and organelles?  By using a microscope of course.

Microscopes allow us to peer into the unseen world around us.

 

🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬

 

Watch this video to see some of the tiny wonders that we often don't realize exist all around us.  This imagery is stunning.

 

🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬

 

Microscopes are delicate pieces of equipment that consists of several parts, that all serve a specific function.

Time to get back to work and learn about the parts and their functions.   

 

🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬🔬

 

If we were in school, we could use an actual microscope.  But, we can still get a feel for the microscope in an online environment.

Check out this virtual microscope.  

Feel free to look at some slides by clicking on "EXPLORE" when you get there.   

Be sure to look at:

• "Letter E" (found in the "Sample Cells"
  
• at least one "Plant Cell" 
• at least one "Animal Cell"
  

SNC 2P - Course Introduction

Hello, my name is Ms. Murphy.  

You may remember me from grade 8 day.  I was the lady that was lighting everything in sight on fire (maybe I even lit *you* on fire 😀).

 I also showed you how fireworks are created.

 

🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

We will be learning completely virtually until February 8th (updated).  So, while we are virtual, our period 2 class will run from 11:45-2:15.  We will meet on Teams at 11:45 every day.

Each day will consist of a mixture of the following: lesson, practice, activity and/or video. The virtual lessons, and any related material can be found on this blog.  

I have created a course timeline that contains hyperlinks to take you to each day's material.  I will pin it in the upper left corner for easy access.  I will update the timeline as needed.

💻💻💻💻💻💻💻💻💻💻💻💻💻💻💻

Before we can get into the science, we have some paper work to get out of the way.  Please have your parents look over the three documents posted here, as well as checking out the rest of the information. 

On a piece of paper, write "We have read and understood the CIS, syllabus and safety rules."  Sign this paper yourself.  Have your parent/guardian sign this paper and send me a picture of it on Edsby.

Finally, please create an account on Wizer.me.  Click the orange "Join now" button and create your free account as a "student."  You can use your board email.

 

WHODUNIT??

Hunt Hints:

👉 A good detective will exercise control over the investigation.

👉 Detectives have to work hard.  There is no free lunch.

👉 A good criminal must fly under the radar, even when in plain sight.

👉 There is a science to catching criminals.

👉 The CSI unit takes pictures of the crime scene and goes through the mug shots.

👉 Correctly following the clues is an art form.

👉 Crime is a messy business.

 

 👮👮👮👮👮👮👮👮👮👮👮👮👮

Each team of detectives will turn in one completed "Police Report."  

All teams with a perfect set of answers will be entered into a draw.  

WHat CaN wE wiN?? 😏

The winning team will not have to write up one lab this semester (excluding the titration lab). They will get all the fun of an experiment without the bummer of the lab report.

 

 

 

 

SCH 4U - Electrolysis

Homework: #30-37

Success Criteria

- be able to determine the oxidation number of an element in a compound or a polyatomic ion.

- be able to define oxidation, reduction, half-reaction, redox reaction, spectator ion, inert electrode, cell, battery, primary/secondary cell, corrosion, sacrificial anode, cathodic protection, electrolysis, etc.

- be able to write out (i) total ionic equation, (ii) net ionic equation, (iii) balanced oxidation half-reaction (iv) balanced reduction half reaction for a redox reaction, (v) provide Eox & Ered, (vi) calculate Ecell and (vii) determine/explain if a cell reaction is spontaneous

- be able to draw a fully labelled galvanic cell from a shorthand notation representing the cell and vice versa

- be able to choose the best/worst oxidizing/reducing agent from a list using E values

SCH 3U - SCH 3U Review

This is the exam review.  It is worth your while to be sure that you can do the questions in this booklet, as it will aid your success on the exam and in future chemistry courses (I'll see some of y'all next year 😉- actually, I won't - I'll be retired - woo to the hoo!!).

The most crucial concepts at which you MUST be proficient are:

• nomenclature (surprise, surpise) ↝ #3-8
• bonding ↝ #14, 18
• predicting products ↝ #20,
• using the Activity Series of Metals and the Solubility rules (as appropriate) ↝ #20
• writing out balanced equations, with the correct state symbols ↝ #20
• writing out total ionic and net ionic equations (as appropriate) ↝ #20
• calculations involving moles, molar mass, mass ↝ #21, 22, 28, 32
• calculations involving pressure, volume, temperature ↝ # 52-56
• calculations involving moles, volume, concentration ↝ # 38, 41, 45, 46, 48
• acid and base definitions and characteristics ↝ #47
• pH scale & calculations ↝ # 39, 40, 49
• stoichiometric calculations ↝ #33, 34, 44, 57-59
• intermolecular forces and properties ↝ #35, 36

Obviously, there are a lot of concepts and skills that you must bring with you into the next step in your chemistry education. You should be able to do all of the above questions without looking at notes/textbook/internet or asking for help from friends/family/tutor.  It is only fair to warn you that the SCH 4U chemistry course is a large step up in terms of time, effort and ability compared to SCH 3U.  So, be prepared. 

Well folks, there's nothing left but the cheering.  We made it.  We survived and we prevailed.
