QUICK LAB

Evaluating SpecializationIn this activity, you will build a paper chain according to specific steps to explore the advantages of specialization. Many of the tasks that are performed in the human body require multiple steps. Different cells may perform different steps in the process. In this activity, you will first build the chain alone, performing all the steps yourself. Then you will coordinate with a group to build the chain, dividing the steps among the group members, with each one specializing in only one function. You will then evaluate the efficiency and productivity of working alone versus working within a group. You will compare this activity to the hierarchical organization of organisms, from cells to organisms.

PROCEDUREReview the following instructions for constructing a paper chain:

A. Use a ruler and pencil to mark strips on a sheet of paper that are 8 inches long and 1 inch wide.

B. Use scissors to carefully cut out each strip.

C. Use a marker to write the entire alphabet on each strip.

D. Make the first loop in the chain by curling the strip end to end and using tape to connect the ends and make a loop.

E. For the rest of the strips, thread one end of the strip through the previous loop, and tape the ends of the strip to form another loop.

Gather your materials.

When your teacher instructs you to begin, make as many loops in your paper chain as you can within 5 minutes. When time is up, count how many loops you have made and record the number below.

__________________________________________________________________________

Form a group with four other students. Add up all the chain loops you each made. What is the total number of paper chain loops made by your group working as individuals?


OBJECTIVES• Evaluate the

advantages of specialization.

• Compare models of unicellular and multicellular processes.

When your teacher says to begin, work with your group to make paper chain loops for 5 minutes. How many paper chain loops did your group make?

__________________________________________________________________________

Did you make more paper chain loops when you were working individually or when you were working with your group?

special powers. Imagine that these superheroes are on a mission inside the human body. Design superhero characters to represent the following specialized cells:

Blood cell Nerve cell Muscle cell

REQUIREMENTS:For each superhero please include:

ILLUSTRATION – Illustrate the superhero inside the body. Make sure it’s superpowers reflect its function (or job) inside the body.

STRUCTURE – Give a 2-3 sentence explanation of the hero’s design and shape.

FUNCTION – Give a 2-3 sentence explanation of the hero’s powers and why they need them.

BACKGROUND INFO:NERVE CELLSCells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 100 billion neurons. Neurons come in many different shapes and sizes. Some of the smallest neurons have cell bodies that are only 4 microns wide. Some of the biggest neurons have cell bodies that are 100 microns wide. Neurons are similar to other cells in the body because they are surrounded by a cell membrane, they have a nucleus that contains genes, and they contain cytoplasm, mitochondria and other organelles. However, neurons differ from other cells in the body because they have specialized cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body. Neurons


Name: _________________________________ Date: _________________ Period: ______

communicate with each other through an electrochemical process. Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).

MUSCLE CELLSA myocyte (also known as a muscle cell) is the type of cell found in muscle tissue. Myocytes are long, tubular cells that develop to form muscles. There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells, with various properties. The striated cells of cardiac and skeletal muscles are referred to as muscle fibers. Cardiomyocytes are the muscle fibers that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the contractions in the esophagus and stomach.

BLOOD CELLSThere are three main types of blood cells: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Hemoglobin (the main component of red blood cells) is an iron-containing protein that facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs. Red blood cells or erythrocytes, primarily carry oxygen and collect carbon dioxide through the use of hemoglobin, and have a lifetime of about 120 days. RBCs (red blood cells) are formed in the red bone marrow in the adults. White blood cells, or leukocytes, are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Platelets, or thrombocytes or yellow blood cells, are very small, irregularly shaped clear cell fragments (i.e. cells that do not have a nucleus containing DNA). They circulate in the blood of mammals and are involved in hemostasis, leading to the formation of blood clots. Platelets release thread-like fibers to form these clots.
