Turn in VIRTUAL Inquiry Lab: Salty Cells & review
Revisit the live video of red onion cells in different solutions.
(Here is another video that may be helpful for viewing cells.)
What you observed happening when salt water was added was called plasmolysis - shrinking of the cytoplasm away from the wall of a living cell due to outward osmotic flow of water (write definition on page with Salty Cells lab)

Review 7.2; 7.3 From Cell to Organism
WARM UP: (2/12/16, left side)
1. What four things do all cells have?
2. What features do only prokaryotes have?
3. What features do only eukaryotes have?
4. Eukaryotes include _______, _______, & _______.
5. Prokaryotes include ________.
6. Name five organelles found in eukaryotes.
Answers:
1. DNA, cell membrane, cytoplasm, ribosomes
2. Single-celled, all have cell wall, some have capsule
3. Nucleus, membrane-bound organelles, multicellular, plants have cell wall
4. Plants, animals, fungi
Just about every organism you're familiar with is a eukaryote. Single celled organisms like yeast, paramecia and amoebae are all eukaryotes. Grass, potatoes, and pine trees are all eukaryotes, as are algae, mushrooms, and tapeworms. And, of course, moles, fruit flies, and you are also examples of eukaryotes.
5. Bacteria
Prokaryotes are all single-celled organisms, most of which you know of as bacteria. For example, the famous (or infamous) Escherichia coli bacterium is a prokaryote, as is the streptococcus bacterium responsible for strep throat. The Streptomyces soil bacteria, from which the antibiotic streptomycin is derived, is also a prokaryotic organism. The entire subclass of archaea are also prokaryotes, mostly remarkable because of their ability to thrive in very harsh environments. An example of archaea is the Sulfolobus acidocaldarius archeobacterium that lives in extremely acidic mud pots in geothermally active areas.
Just about every living organism on Earth can be placed in one of two classes: prokaryotes and eukaryotes. A prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote. All prokaryotes are single-celled organisms. Some eukaryotes are also single-celled organisms, but every multi-celled organism is eukaryotic.
6. Mitochondria, nucleus, nucleolus, lysosome, ribosome, smooth endoplasmic reticulum, rough endoplasmic reticulum, golgi apparatus, vacuole
-Check for flashcard completion
Of the flashcards, there are a few terms we didn't discuss in our notetaking on Wednesday. Let's do that now.
nucleolus - the "brain" of the nucleus; responsible for ribosome synthesis and production
chloroplast - found only in plant cells; site of photosynthesis
lysosome - breaks down waste in a cell
cytoplasm - in a eukaryotic cell, includes all the material inside the cell (organelles) but outside the nucleus; everything contained inside the membrane
cytosol - gel-like substance in between organelles
OVERVIEW OF CELL STRUCTURE VIDEO (7:21 MIN)
7.3 From Cell to Organism
How is a multicellular organism organised?
The biological levels of organization of living things arranged
from the simplest to most complex are:
organelle, cells, tissues, organs, organ
systems, organisms, populations, communities, ecosystem,
and biosphere.

IF YOU MISSED THE CHEEK CELL LAB GO HERE!
-Here is a virtual lab you can do to make up the Cheek Cell Lab we did in class on 2/8/16: VIRTUAL CHEEK CELL LAB
Read and follow the directions carefully. Answer the questions and turn them in to me for credit.

7.2 Inside the Eukaryotic Cell
2nd & last night of forecasting is tonight 6-8pm
Tutorial tomorrow & Friday
Tutorial tomorrow & Friday
Turn in Cheek Cell Lab for 25 points
-WARM UP: Sketch one cheek cell on the processing side of your notebook and label the cell membrane, cytoplasm, & nucleus from this photo taken during lab by a fellow student:
With neighbor:
-What kind of cell is this? (prokaryote or eukaryote) What is your evidence to prove this?
-What cell parts should be in the cell that we can't see with our microscopes? (all cells have these)

7.2 Inside the Eukaryotic Cell (top right hand side) 2/10/16
Learning Objective: I can identify the structures and functions of eukaryotic cell organelles.
-Notes on the right hand side:
The cytoplasm of a eukaryotic cell is filled with many structures and molecules that are organized into regions. This organization enables each organelle to perform highly sophisticated and specialized functions.
The Framework of the Cell
-The cytoskeleton's network of protein fibers anchors cell organelles and other components of the cytoplasm.
Directing Cellular Activity
-Almost all cellular activity depends on the proteins that the cell makes. The instructions for making proteins are stored in the DNA, which is found in the nucleus of the cell.
-Ribosomes are made of RNA (ribonucleic acid) & proteins
Protein Processing
-Endoplasmic reticulum is a system of membranes that move proteins through the cell. There are two types of ER:
rough ER - has ribosomes attached
smooth ER - has no ribosomes
Storage and Maintenance
-Vesicles help maintain homeostasis by storing and releasing various substances as the cell needs them.
-Organelles involved in storage & maintenance:
lysosomes, vacuoles, chloroplasts (only in plant cells), mitochondria
-Brain Break: Cell Rap
-Now make flashcards using Key Vocabulary Terms. Be creative! Use color and drawings to enhance memory retention and understanding. When finished, quiz your table partners!

Cheek Cell Lab
-Happy Lunar New Year! It's the Year of the Monkey!
-Hand back Root Word Quiz #4 (good job!)
-As a review of what we've learned so far about prokaryotic cells and eukaryotic cells, let's review Amoeba Sisters: Prokaryote vs. Eukaryote worksheet answers. This will get glued into the right hand side of your notebook.
Cheek Cell Lab (2/8/16)
Learning Objective: I can prepare and examine a slide of a cheek cell in order to better understand cell structure and function; I can provide evidence to determine if human cheek cells are prokaryotic or eukaryotic.
Cell Theory, developed by scientists in the 1800's, states:
1. All living things are made up of one or more cells
2. Cells are the basic units of structure and function in organisms.
3. All cells arise from existing cells.
-Review Lab Safety rules & microscope use procedures
-Ms. Ferro will demonstrate correct procedure for this lab
-Do Cheek Cell Lab using microscopes (25 pts)
See if you can get a good photo of your cells with a phone.
Finish for homework, due beginning of class on Wednesday
