Cell Specialization Lab



Cell Specialization Lab

Introduction

The human body, like the body of any animal or plant, is made up of many millions of individual cells. But these cells are not scattered through the body in disorder or confusion. The body is a well-organized community of cooperating cells.

Cells adapt themselves and develop into a remarkable variety of different forms and sizes. Similar cells group together to perform similar work. The work these cells do is called a special function of the cells, and the group of cells itself is called a tissue. In turn, tissues group together to perform a special function. Such groups of tissues are called organs of the body.

Directions

In this lab each student will be observing and reading about different types of tissues found in multi-cellular organisms. For each station, please read the information given on the card. Then, please draw what each tissue looks like. Last, answer the questions about that tissue in the space provided. Each student must stay at his/her station until it is time to rotate.
