Transcript of Biology - Cells - Ms. Boyea

Cell Unit
This is the prezi for Ms. Boyea's entire Cell Unit. To get to a specific day just click on it and it'll zoom in!
Answer the analysis questions on your handout
Why don’t organism not just melt into their surroundings?

Especially life that lives in water
I am a living organism now. How will there continue to be life after I am dead?
What is the function of DNA?
What cell process does every organism do?

What does this process need?

What was harnessed in photosynthesis to make sugar?
5. All living things maintain
homeostasis
homeostasis = an organism and/or cell that regulates its internal environment and maintains a balanced cell condition
It is regulated by feedback.
Feedback
is a response to a stimuli like water balance, pH, temperature or hormones.
Characteristics of Life
4. All living things can
reproduce
Reproduction is the process of making offspring
Characteristics of Life
2. All living things have
metabolism
(use energy)
by cell respiration and this allows growth and/or movement
Characteristics of Life
1. All living things are made of
cells
some organism are 1 cell and others are many organized cells working together
Characteristics of Life

Why do we look the way we do?

Why does a tree look the way it does.
What's your body made of?

What's a tree made of?

Your answers:
What is an overarching characteristic of life?
Think-Pair-Share:
Turn in your Ebola Reading Questions! Today starts grades for 2nd Quarter!

What is life? Write a 3-5 sentence paragraph that supports your definition of life. Think about what you consider alive and why you think so.
Drill:
Answer the BCR on your handout you have ______ minutes
Exit Ticket: Alien BCR


HW: Last Page of
Characteristics of Life
3. All living things contain
heredity
which means they have genetic info like DNA
having heredity means you can pass traits to offspring
Characteristics of Life
Objective: Students will formulate the characteristics of life in order to justify whether a sample is biotic, abiotic or nonliving.
Cell Biology Unit: Day 1
Characteristics of Life
You will view one specimen at each designated lab station. Write the object in data table.

Decide if the specimens is biotic, abiotic or nonliving based on your definitions above. Write it in the data table.

List at least 2 observations that support your conclusion of biotic, abiotic or nonliving. Write your evidence in the data table

You will have 1 minute at each station. Move when the teacher announces.
Gallery Walk
Day 1: Characteristics of Life
Objective: Students will formulate the characteristics of life in order to justify whether a sample is biotic, abiotic or nonliving.
Anything that is alive, was alive or came from a living thing.
Anything that is NOT alive, but is essential for life
Anything that has never been alive and isn't essential for life
Take notes!
advantage: disadvantage:
3. What is an advantage and disadvantage of being a prokaryote?
2. What do you think are 2 reasons why it would be better for a cell to have its DNA in a nucleus?
1. Justify which type of cell is MORE advanced Pro or Eukaryotic
Answer the following questions as your exit ticket for the day.
Analysis questions – Exit Ticket
Samples from your scavenger hunt:
Cells with a Nucleus. Nucleus separates genetic material (DNA) from the rest of the cell.
Cells with membrane bound organelles
Eukaryote
Lacks a nucleus! Genetic material is in a clump but doesn't have its own membrane.
Example: Bacteria
Prokaryote
1. All living things are made of cells
- This one is also a characteristic of life!
2. Cells are the basic unit of structure and function in living things.
- Some complete organisms are made of just one cell and others are made of many.
3. New cells are produced from existing cells
- Life comes from life
Cell Theory
People use bacteria to clean up after oil spills.
Students will describe the characteristics of eukaryotes and prokaryotes,

In order to determine the advantages and disadvantages of specific cell types
Objective
Distinguish between the terms unicellular and multicellular
Drill
4. What is an advantage and disadvantage of being a eukaryote?
Both cells have:
DNA as their genetic material
A cell membrane to surround the cell
Cytoplasm is the jelly-like substance that fills the cell

(we'll talk about these more soon)
Similarities Between Pro/Eukaryotes
Prokaryote
Bacteria don’t often reproduce.
There are millions of species of bacteria that can make people ill.
Swamps produce terrible odors because owls shower them with nasty-smelling antibacterial sprays.
Some scientists believe that, long ago, certain supertough bacteria may have hitched rides to Earth on meteorites.
At any given time you have about a billion bacteria on every tooth of your mouth.

Day 9: Cell Membrane Explained
Drill:
Turn in your HW!
Why do your cells need a cell membrane? Why won’t a cell wall do the job?
Objective: Students will describe the properties of the cell membrane in order to determine the movement of particles across the cell membrane
This is a summary of everything you need for your second Quiz in the Cell Bio Unit
The Function of the cell membrane:
The membrane regulates the exchange of




gases, absorption of nutrients & removal of waste
The membrane is selectively semipermeable, which means




it selects to let molecules in and out of the cell. Its made of a phospholipid bilayer
Channel or Pump
Polar

Polar
Nonpolar
Proteins
Phospholipid
The purpose of the cell membrane



to maintain homeostasis which means balance
Different ways for molecules to get across the membrane:
(Brainpop: Passive Transport)
1. Diffusion:
is the movement of molecules across a membrane from a high concentration to a low concentration
Osmosis:
is diffusion of water across a membrane
Hypotonic Solution:
when comparing 2 solutions its the one with the LEAST solute
Hypertonic Solution:
its the one with the MOST solutes
Isotonic Solution:
The solutes are the same in both
2. Facilitated Diffusion:
Some molecules don't move through a membrane so they need a special channel to move from high to low concentration
3. Active Transport:
Uses energy to pump against the concentration gradient
4. Endo/Exocytosis:
Active Transport
Endocytosis:
Brings substances in by making a vacuole
Exocytosis:
sends substance in the vacuoles out of a cell
Exo
Endo
Cell Size: Cells need to have a
HIGH
surface area to volume ratio in order to exchange ions, gases, nutrients and wastes that need to
DIFFUSE
through the cell. When a cell grows in
VOLUME
the
SURFACE

AREA
can't keep up so the cell needs to reproduce.

Osmosis Practice!!!!

Constraints:
1. Students must use supplies available in classroom
2. Egg must be ready for shipment next class
3. Students must have a written plan before they are given their 2 eggs to set up
4. No part of the egg can be removed

Elodea: Test Cells
Before you create your experiment, you can test 2 solutions on plant cells (20% NaCl and H2O). Elodea cells behave like the salmon eggs.

1. Which structure is the boundary between a living cell and its environment?
2. In the diagram of the root cells, three areas are indicated with the numbers 1, 2, and 3. In which direction would the net flow of water be the greatest as a result of diffusion





3. What is most common type of molecule present in the bacteria cell membranes?
4. Which cellular structure is present in both eukaryotic cells and prokaryotic cells?
5. Many bacteria live in saltwater. Which of these statements best describes what will happen when saltwater bacterial cells are placed in freshwater?
6. Which statement best describes a cell membrane?

A. It is found only in animal cells
B. It is a nonliving structure
C. It controls reproduction in a cell
D. It controls the passage of materials into the cell.

7. The cell membrane is permeable ONLY to water. Describe the beaker and the cell in terms of water.




















8. What is the process that will occur in the animal cell above?
9. Which part of the cell membrane is hydrophilic





10. Why did the plants in Groups E and F died?









11. This process is called?




Starch turns blue-black in the presence of iodine solution. A selectively permeable dialysis sac containing a starch solution is placed into a beaker of iodine solution.












12. The dialysis sac is permeable only to water and iodine and is not permeable to starch. What will the solutions in the beaker and the sac look like after two hours?
13. Which of these processes is demonstrated by the experiment shown in the diagram?
Cell Membrane
A
Lipid
Cell Membrane
Expand and Explode
controls passage of materials into the cell
Higher water in the cell
B
Endocytosis
Sac-Black
