THE STUDY OF LIFE

Microbiology

Warm up 1/12/12

Read the statement below and defend (back up) or dispute (argue against) the claim:

“Something is alive when it has the ability to think, breathe and move”

Announcements

There will be no tutoring next Monday. MLK day.I will stay afterschool on Tuesday of next week.I will have grade conferences on Tuesday to let

you know your current grade and what you need to make up.

It is your responsibility to see me to get this work. I will be calling parents with FAILURE notices on

Tuesday as well. Therefore, get your work done and make it up now, so that I can update it.

Being absent, is not an excuse. It is your responsibility to get the work done!

I Robot Video

Be sure to pay attention to the differences between the human (Will Smith) and the Robot.

As you are watching, keep these questions in mind:

1. How are the two similar?2. How are they different?3. What is the difference between a Father and

Creator in this case?4. Why is this robot considered strange?

What makes something living?Watch this clip from I, Robot

Reflection Questions

With a partner, answer the following questions on your worksheet (4 min)

1. Do you think the robot is living or non living?

2. What “requirements” must something have to be considered living?

Create a list of at least 3 (observable) requirements

LIVING

One partner come to the board and write down ONE WORD that you think makes

you living…

Characteristics of living things

Living things have these characteristics:

1. Organization2. The ability to grow and develop3. Respond to stimuli in their environment4. The ability to reproduce

Organization

Organized- living things need to be organized so that it can conduct all of the things necessary to be alive.

Some organisms are simple (bacteria) while others are more complicated (human beings). As a result, bacteria is less organized than a person.

Growth and development

The needs of an organism also determines how it grows, changes and develops.

Some change very quickly and grow fast, while others are slower.

The changes that take place are based on what the organism needs to survive.

Response to stimuli

All things that are alive need to react to things going on around them.

If they could not, they would not be able to adapt to things so that they could stay alive.

Reproduction

If things don’t reproduce, how could they keep living?

Simply put, living things need to replenish themselves or they would go extinct.

Being Alive vs. Being a Living Thing

Being alive means that you are not dead! This means that you continue to change, grow, and respond to your environment.

Being a living thing means that you’re not nonliving. Therefore, you meet all four requirements of being a living thing.

Practice (2 mins)

List the following items in your notebook and classify them as living or non living:

1. Tree 2. Spider3. iPhone4. Chemicals 5. Bacteria6. Frogs 7. Nitrogen 8. Alge

All Living things are…

MADE OF CELLS

What are Cells?Cells are the smallest unit of life.

Living things can be unicellular or multicellular.

How Many Wheels Does a UNIcycle have?

Therefore, how many cells does a UNIcellular organism have?

Unicellular

• unicellular – made up of only one cell

Ex: bacteria, ameobas

Multi-cellular

• multicellular – made up of many cells

Ex: Man, killer whale, plants

Independent practice

Reflection: Think back to the video clips that we watched

in class.Think back to the characteristics of living

things. In 2 paragraphs or more write a response to

my claim:“Robots like Sunny in the movie I Robot have

feelings, thoughts and can move around just like humans. They are able to things that people can do. Therefore, they should be classified as living.”

Warm Up 1/13/12

In at least 1 paragraph (5 sentences) describe what qualities make something alive. Choose an example of something that is alive and something that is dead and describe their similarities and differences.

Cells Part 2

All living things are made up of cells.Cells are the smallest unit of life.Cells only come from other living cells.Living things can be made up of one cell or

multiple cells.

Lets recap on what we have learned so far…….

Unicellular

Organism made up of one cell.Usually too small to see with the naked eye.

Multicellular

Organisms that are made up of more than one cell.

These organisms have many different cells that perform different jobs in order to meet the organisms needs.

Examples include:Volvox, Frogs, Human beings, etc.

Prokaryotic vs. Eukaryotic Cells

Cells are made up differently based on the needs of the organism. The inside of one cells can be very different from one another. However, we can classify cells into two groups:

Eukaryotic Cells- genetic material (DNA) is enclosed in the nucleus. Most multicellular organisms are eukaryotic. Plants and animals have eukaryotic cells.

Prokaryotic cells- there is no separate place for genetic material. Most prokaryotic cells are unicellular.

What is inside a cell?

Organelles are things inside a cell that are enclosed by a membrane.

The cell membrane is the outer boundary of the cytoplasm. It controls what enters and leaves the cell. It is also a protective covering that encloses the entire cell.

Bubble Lab

Today we are going to study the cell membrane and talk about how things enter and exit the cell.

Independent Practice

1. What is the difference between a prokaryotic and eukaryotic cell?

2. What job does the cell membrane play within the eukaryotic cell?

3. Think about the structure and function of the soap bubbles and the cell membrane. Describe how they are similar and how they are different. You may do this using a chart or in paragraph form.

Differences Between Plant and Animal Eukaryotic Cells?

Where do plants get there energy from?Where to animals get there energy from?

Therefore, plants have chloroplasts and central vacuoles that help them turn solar energy into food and store their water. They also have a cell wall.

Animal cells have none of the above. Instead of a central vacuole, an animal cell has lysosomes that break down materials (food) that are brought into the cell.

Quick illustrations

Turn to page C21The pictures at the bottom show the differences between

plant and animal cells up close using an electron microscope.

Turn to page C22In your notebook draw both cells and label all of the parts.Be sure to highlight the parts of the plant cell that are not

present in the animal cell!You will need these drawings to review for your test on

Cells! You have 8 minutes for both drawings. I am setting the

timer and moving on!

Jot down all the differences between the two types that you hear. If there is talking you will have a quiz.

Cell Organelles/Worksheet

Each of you will receive a foldable to take your notes on.

Each flap will represent a different organelle

Diffusion

This is a process where molecules move from an area of higher concentration to an area of lower concentration.

Ex.When you spray perfume, the smell is more

powerful up close but over time the molecules spread out and it can be smelled throughout the room.

Osmosis

Molecules move from an area of higher concentration to an area of lower concentration across a membrane.

This definition is the same as diffusion except it takes place across a membrane.

That is, things move in an out of a cell.

Eukaryotic Cell Parts

Function

Cell Membrane Provides a barrier between the cell and its environment. All nutrients and waste move across the cell membrane.

Nucleus Controls the functions of the cell. Acts as the “brain” of the cell.

Mitochondria Makes energy that can be used by the cell.

Cytoplasm Gel like substance that holds organelles in place

Lysosome Breaks down waste into a form that can be removed from the cell. Breaks down the cell itself if the cell is damaged or

old.

Endoplasmic Reticulum Transports nutrients and waste within the cell.

Vacuoles Holds water transported into the cell until used by the cell.

Ribosome Translates or puts together genetic information (DNA/RNA) to make protein.

Golgi Bodies/apparatus Processes and packages proteins before they go where they are needed

Eukaryotic Cells

Exit ticket

The main job of the nucleus is to?a. remove waste from the cellb. give the cell its shapec. control what goes on in the celld. give the cell its color

2. Which is the primary function of mitochondria in animal cells?a. to release energyb. to provide supportc. to store materialsd. to transport waste

3. How do lysosomes function inside the cell?a. Lysosomes manufacture proteins for the cell.b. Lysosomes distribute enzymes throughout the cell.c. Lysosomes assist the nucleus in DNA synthesis.d. Lysosomes serve as the cell’s digestive system.

Review of cell organelles

Look over your note sheet from last class. Using your vocabulary words, select an

organelle that you like.

Roles

Each of you will be randomly assigned a cell organelle.

You will write a scrip that describes your role within the club.

This will count as your quiz on cells.

You have 20 minutes.

What I’m looking for

Your script MUST include:1. Your job within the cell.2. How you help the cell to maintain homeostasis.3. Describe your interactions with the other cell

organelles.4. Include what type of relationships you would

have with the other organelles. How would you be closest to in the cell? Who would not get along with?

5. Be as creative and colorful as possible.6. You may include a diagram.

On your index card, write a brief summary of your script.

SO THAT YOU CAN REMEMBER WHAT TO SAY!

Time to practice

All organelle groups will get together and plan their role within the cell.

You will have 5 minutes until show time.Make sure everyone is on the same page. You are the same organelle and should be

doing the same thing!!!!!

You will be videotaped…..

When I say show time, the club scene will begin.

Pretend we are shooting a music video.When I say action act out your part….

Reflections, thoughts

Jot down what you learned from today’s activity.
