INTRODUCTION

Every living thing is composed of at least one cell. Bacteria, amoebae, and paramecia are made of one cell and are capable of the activities of life. Organisms made of one cell are unicellular. Most living things are made of more than one cell and are called multicellular. Cells of these organisms function together to accomplish life activities. How many cells do you think make up your body? The human body is made of trillions of cells.

In order to understand how the cell functions in your body, we have to take a look at how your body is organized. Since you are made of matter, and all matter is made of atoms, your body is a collection of atoms. These atoms combined in specific ways to form molecules. Some of the important molecules in your body are proteins, carbohydrates, lipids, salts, water, and nucleic acids. These molecules combined to form the structures that make up a cell. Since each cell is capable of the activities of life, it is the smallest unit of life.

Cells that are similar can function together. These collections of cells are called tissues. Some tissues that you may be familiar with are the muscle tissue that makes up your heart, epithelial tissue that makes up your skin, and connective tissue that holds your body together. Different groups of tissues can be arranged to form organs. Some organs that you may be familiar with are the stomach, intestines, heart, and lungs. For example, the stomach has epithelium to line the outside and inside surfaces for protection and the muscle tissue allows your stomach to squeeze and churn. Groups of organs can work together as an organ system to perform a specific function. The digestive system functions to breakdown and absorb food so that our bodies can use the energy. The pancreas, stomach, intestines, gall bladder, and esophagus are some of the organs that make up the digestive system. There are 13 systems in the human body that function together to produce an organism – YOU!

The focus of this activity is to learn more about the cell and how it functions in your body.

CELL SIZE

Cells are very small and you must use a microscope to look at them. Watch this video (click on “start animation”), then look at the size of cells and answer the following questions. To give you an idea about size, the length of a key on the keyboard is about 1 cm.

Question:
Answer:
A. Is a bacterium larger or smaller than an animal cell?
B. How many bacteria can fit into an animal cell?
C. Are plant cells larger or smaller than animal cells?

 

EUKARYOTIC CELL ORGANELLES

Since the cell is the fundamental unit of life, it must be capable of independent existence. Some of the necessary life activities are communication, metabolism, protection, and waste disposal. In order to carry out these jobs, the cell has different organs inside of it just like your body has organs. These “tiny organs” are called organelles. Different organs have different jobs and they need the proper supplies of ATP (cellular energy), proteins, oxygen, and other nutrients to carry out their jobs.
There are different types of cells that have different functions, but all cells have some common features. The things common to all cells are a cell membrane (plasma membrane), cytoplasm, and organelles. Take a look at a drawing of an animal cell. (Hold cursor over organelle to identify it.)

To understand how the cell carries out its functions, you should know more about the cytoplasm, cell membrane, and organelles. Click on each structure given in the table below to learn more about each cell part. Complete the table by writing a brief description and function for each part.

The things common to all cells are a cell membrane (plasma membrane), cytoplasm, and organelles. Remember that plant cells have three structures that animal cells don’t.  Now look at a drawing of a plant cell.  (Hold cursor over organelle to identify it.)

After you have read about  cells, take the cell quiz. Check your answer after you answer each question.

Build a Cell

Use of our material:
This activity was created by Kelly Riedell for students in Biology class at Brookings High School. We have worked very hard on activities, Powerpoints/games/worksheets, etc to make this a resource for our students. If you are using our materials, please give us credit for our efforts by listing us as a source with links to our site.
Any questions, comments, or corrections can be directed to us at

BUILD -A-CELL GAME
Students review by answering questions AND
by practicing what parts look like and their
location as they build their cell.

AHEAD OF TIME:
1. Make a copy of the question cards. and cut them apart
You will need a set of question cards for each group of 4
I make the sets different colors so the cards don’t get mixed up.

2. Print out the Build a cell game parts sheets.
Copy the blank cell page onto colored paper (1 for each student)
Copy off the cell parts pieces onto clear transparency sheets, cut out,  and place in
paper lunch bags. (1 lunch bag per game group with enough parts in it to make 4 cells.)
Using clear transparencies allows some cell parts to build on top of each other.
(Ex: nucleolus goes inside nucleus, ribosomes sit on top of Rough ER)

PLAY THE GAME:
Students play in groups of 3-4. Each group has a lunch bag with cell parts pieces and a deck of question cards. Each student has his/her own blank cell score sheet. Students play by taking turns answering questions.  If they answer correctly, they get to pick a cell part from the lunch bag and place it on their cell scorecard in the correct place. If they get  it wrong they don’t get a part and the next student gets a turn.

First student to get all 9 cell parts into their cell is the winner.

Build a Bug

 

Build-a-Bug

 

Introduction:

Most adult insects have the following characteristics:

    1. A body divided into three parts (head, thorax and abdomen)
    2. Three pairs of legs
    3. Usually one pair of antennae and a pair of compound eyes (a few exceptions to these characteristics are found)
    4. Usually two pairs of wings (absent in many insects such as lice, fleas, ants; flies have one pair of wings)

There are approximately 30 orders of insects. Choose one of the insects from these orders.

INSECT ORDERS

Click on the link to learn more about the characteristics of that order. There are links to specific insects on each page.  Visit the Field Guide Index to see a listing of all insects featured in the Field Guide.

Objective:

Students will build biologically correct insects in order to learn insect structure and adaptations.

Materials:

Any non-food item such as cardboard, egg cartons, clay, wire, felt, Styrofoam, pipe cleaners, nylon stockings, pipe cleaners, paint, glue, string, etc.

Guidelines:

  1. Your model must be an INSECT (i.e. no spiders, mites, ticks, centipedes, or millipedes, please). Note: Your insect does not have to live in the United States.
  2. Your model must be between 6-12 inches long, and sturdy.
  3. Be accurate when building your model (appropriate proportions, true color and form, etc.).
  4. The more detail your model has, the better.
  5. A written description must accompany your model and include:
  • The common name of the insect
  • The name of the order to which it belongs
  • A brief description of the insect’s habitat
  • Where the insect is located geographically
  • At least 2 interesting, and unique facts about the insect you have modeled (i.e. “it has 6 legs and 3 body segments” doesn’t count)
  • Your name and address on model description
