Bio 9C: Friday, 9.24.10Title: What are cells?
Homework: (change from assign
sheet) No Homework
Do Now: Set up today’s
notebook entry with the title and date in the proper format!
Write down at least 3 observations about what you see in the picture
Today’s Objectives:1. Identify 3 components that ALL cells
have2. Explain why cells are important to all
living things3. Explain where the heck cells come
from4. Maintain a neat and organized
scientific notebook

Scientific Notebook Guidelines
Each entry should have… Date (outside corner, under page #) Title Do Now (clearly labeled) Notes – accurate, complete, detailed, w/ labeled diagrams! Neatness
Other Guidelines: Only Bio! Never tear out a page! Use your 2-pocket folder! Key handouts stapled in! Keep it nice!
You get graded on all this!Class Objectives: 1. Maintain a neat and complete scientific notebook
Taking Notes in Class: Class Norms
Purpose: Review and add details to the notes you took from the
reading Discuss and ask questions about the day’s topic Draw diagrams so you can picture what we’re learning
How it works: “Cold calling” – I will call randomly on students to check your
understanding of the reading assignment and your ability to think on your feet!
If you don’t know, that’s ok – just say so. BUT you’re not off the hook – I will ask you to listen and repeat the answer to be sure you’ve got it!
During notes, you should be: Quietly writing down notes and drawing diagrams from the board
UNLESS they’re a repeat of your HW Listening and ready to answer a question about the HW Asking questions about things you don’t understand or things you
want to know more about!
What do you see?

a bunch of different types of cells working together.

Eukaryotic Cell Diagram Labeling
Work with your partner from the Microscope Tutorial to label the plant and animal cell diagrams (do your best, the book diagrams and these diagrams do not match perfectly… this is a good thing!)
Class Objectives: 1. Identify the major organelles in a eukaryotic cell2. Explain the functions of the major organelles in a eukaryotic cell
Cell Organelle Speed Dating Planning
Organelle Speed Dating Planning: Working with your partner from the Eukaryotic Cell
Labeling activity, research the cell organelle that has been assigned you.
Specifically, you are need to know the key structures and functions of your organelle.
Use the template titled, “Speed Dating Planning” to help organize your information (this is on the back of your Eukaryotic Cell Diagram Sheet).
This needs to be completed by the beginning of tomorrow’s class.
Take on the persona of your organelle. Class Objectives: 1. Identify the major organelles in a eukaryotic cell2. Explain the functions of the major organelles in a eukaryotic cell
Bio 9C: Tuesday, 9.28.10Title: Eukaryotic Cell Organelle Speed Dating
Homework: Complete the Cell Organelle Review and Speed Dating
Reflection Assignment Complete the pre-lab for the Cells Under the Microscope
Lab.
Do Now: Make a BIG circle with the desks and set the chairs
up on either side of the circle Find your organelle label at the lab benches and sit
ACROSS from your organelle buddy
Objectives for Class:1. Identify the major organelles in a eukaryotic cell2. Explain the functions of the major organelles in a eukaryotic cell3. Make connections between the major organelles in a eukaryotic cell
Organelle Speed Dating Rules: Pair With your organelle buddy:
Your instructor will distribute slips of paper with a description of each organelle.
Find the one that matches YOUR organelle and compare that description with the ORGANELLE SUMMARY on your Speed Dating Planning sheet.
If the descriptions are the same… you’re all set. If the descriptions are different, use the description on the slip of paper to tell other organelles about yourself. (4 min)
When you meet another organelle (3 minute rounds): Introduce yourselves and shake hands Find out each other’s jobs (1 min.) Find a connection between the two of you – how do your jobs relate?
(1 min.) Record information in the Organelle Chart. Inner circle rotates one seat to the right.

Bio 9C: Friday, 10.1.10Title: A day in the life of a cell
Homework: 1. Due Tuesday: Detailed paragraph (must be typed)
Describe how the organelles in a cell work together to make and use proteins. Include at least 5 different organelles in your essay.
Note: you will also have a quiz on Tuesday Do Now:
What comes to your mind when you think about proteins? What do you think a protein is and why do you think proteins are important.
Objectives: 1. Identify the major organelles in a eukaryotic cell2. Explain the functions of the major organelles in a eukaryotic cell3. Make connections between the major organelles in a eukaryotic cell4. Explain how at least 5 cell organelles work together to make and
use proteins in your body
Characteristics of Proteins Proteins are large molecules that do many
important jobs in living things, such as: Form body structures (muscle, bone,
hair, nails, skin) Act as enzymes to speed up chemical
reactions (like digestion) in our bodies Act as hormones that send signals
through the bloodstream
[And many other things we’ll learn about later!]

Review: Organelle FunctionsFunction Cell Structure/OrganelleMakes proteins by following instructions from DNA.
Uses sunlight energy to make sugar (photosynthesis)
Contains DNA, which controls cell activities and reproduction.
Digests food and cell wastes.Breaks down food to release energy that the cell can use (cell respiration)Stores water and nutrients for the cell. It is especially large in plant cells.Modifies and transports proteins, and assembles lipids into membranes.Modifies, sorts, and packages proteins for storage or to be shipped out of the cell.A barrier around all cells that controls what enters and leaves the cell.Helps to support the cell and give it shape, and helps with moving organelles or moving the whole cell.
A sturdy structure outside the cell membrane that provides protection and support. Found in plant but not animal cells.
The entire part of the cell between the nucleus and the cell membrane. Filled with water, nutrients, and organelles.
