Cells Alive!Purpose: In this activity, you will discover the importance of each cell and its parts in our body. Each plays an important role in our development!

PART A: Cell Intro: Answer the following questions. You will have to look these up!

1. What is a CELL? ______________________________________________________________________________

2. What does it mean to be UNICELLULAR? __________________________________________________________

3. Identify an organism that is UNICELLULAR: _________________________________________________________

4. What does it mean to be MULTICELLULAR? ________________________________________________________

5. Identify an organism that is MULTICELLUAR: _______________________________________________________

6. Your body is made up of an estimated ________________________________________________________cells!

PART B: How Big is a…?”: Visit the following website: www.cellsalive.com

1. Select “Cell Biology” from the left hand menu.

2. Visit the “How Big is a…?” section of the site to get a better perspective on the variations of cell size. You should

see an image of a pinhead. Manipulate the zoom to view different examples on the pinhead.

PART C: Label Diagrams

1. Next, under Cell Biology, click on Cell Models, and select “Bacterial Cell”. In this section you will discover the

significance of the bacterial cell and its parts!

Explain the function of the labeled parts #1-6:1.

2. Cell/Plasma Membrane (part of the cell envelope portion)

3. Ribosomes

4. Pili

5. Capsule

6. Nucleiod/Genopore

1. Flagella

2. Now select the “Plant and Animal Cell Animation” link from the top of the page. Once there, click on the animal cell and label the following parts below.

3. After looking at the bacterial cell and the animal cell, which one is more complex? Circle

4. Is the animal cell a prokaryote or a eukaryote? Circle

PART D: Animal Cell Model

For this model, you will need to click on the various parts of the cell to go to a screen that tells you about the parts. Answers to the following questions are found there.

1. What do mitochondria do? Sketch each of the following and COLOR!

2. How big are mitochondria?

3. What is the difference between smoothAnd rough ER?

4. Where specifically is the nucleolus found?

5. What does the cytoskeleton do?

6. Cytosol goes by what other name?

7. How does the golgi apparatus work?

8. What is the main function of the cellmembrane/plasma membrane?

PART E: Plant Cell Model

You will need to return to the “Cell Models” link to access this page, or hit your back button

1. What specifically makes the plant cells green? Sketch each of the following and COLOR!

2. Where does photosynthesis take place? (if you can’t find it, research it!)

3. In plant cells, what does the vacuole do?

Golgi Apparatus

Plasma Membrane (Cell Membrane)

Chloroplast

Vacuole

PART F: Overview

For the chart below, place a check in the box if the cell has that component. You will need to view the plant and animal cells in order to do this.

Plant Animal

Plasma Membrane (Cell Membrane)

Vacuole

Large central vacuole

Mitochondria

DNA

Endoplasmic Reticulum

Cell Wall

Golgi Apparatus

Nucleus

Chloroplast

Ribosome

Flagellum/Cilia

Lysosomes

Peroxisomes

PART G: Analysis

Click on “penicillin” in the MICROBIOLOGY navigation bar to construct an organized paragraph which explains antibiotic resistant bacteria. Include the following:

What are antibiotic resistant bacteria? Why has there been an increase in antibiotic resistant bacteria? How could it be reduced?
