CELL EXPLORATION WEBQUEST
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!
To review:
ATOMS ------> MOLECULES -------> CELLS -------> TISSUES -------> ORGANS ------> SYSTEMS ------> ORGANISM
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.)
