Background:
Cells are the smallest living unit and some organisms consist of only one cell (they are unicellular). There
are many types of unicellular organisms, but all of them are quite simple and small. Some examples, as
seen through a microscope, are included in
Figure 4 – 1
E. Coli
Paramecium
Micrasterias
Figure 4-1
Not all cells form single organisms, however. Organisms that can be easily seen with the naked eye are
multicellular (composed of many cells). Multicellular organisms are more complex and usually consist of
organized groups of cells (called tissues) that perform specific functions.
Within cells are specialized structures that perform specific tasks (just as various organs within your body
perform specific functions). These small structures reminded the first scientist who observed them of
body
organs, so they were named organelles (which means “tiny organs”). You may be familiar with one
example of an organelle – the mitochondria- but cells contain many others.
Regardless of whether an organism is unicellular or multicellular, its cells will fall into either of two
distinct categories: prokaryotic (simple structure) or eukaryotic (more specialized).
Fundamentals of Biology. Online Labs. Lab3
There are several ways to distinguish between prokaryotic and eukaryotic cells.
Table 4-1
summarizes
the main differences.
Prokaryotic
Eukaryotic
Organelles not enclosed by a membrane
Many types of membrane-bound organelles
Simple organization
Complex organization
Genetic material free-floating within cell
Genetic material enclosed in a nucleus
Small in size
Many times larger (but still microscopic)
Single celled
Often multicellular
Activity 1
1.
Label each unicellular organism in Figure 4-1 as either prokaryotic or eukaryotic.
2.
Are your body cells prokaryotic or eukaryotic? Explain your answer
Activity 2
1.
Using the characteristics of internal and external structures listed in your text book draw a
simplified prokaryotic cell and a simplified eukaryotic cell in the spaces provided below. Make
your drawings large so you can add additional parts later. Include and label: cell membrane,
cytoplasm, ribosomes, and genetic material
Prokaryotic cell
Eukaryotic cell
2.
What organelle(s) do your two cells have in common?
3.
In regard to your drawings, what are the most important features you used to differentiate
between the prokaryotic and eukaryotic cells?
Fundamentals of Biology. Online Labs. Lab3
Activity 3
Eukaryotic cells are more complex than prokaryotic cells. This complexity derives from the fact that they
contain more organelles and are able to perform a greater variety of functions.
1.
Using information from your textbook and the Internet, go to
Table 4-3
, then, enter the name of
the cellular organelle that performs each of the functions.
2.
Figure 4-3 contains the outline of a eukaryotic plant cell. The outline represents the cell
membrane and cell wall of the cell. Search the Internet for a photo of each organelle listed in
Table 4-3.
Using the photos your find as a guide, add a drawing of each organelle to the cell
diagram in
figure 4-3.

The Importance of the Cell in Human Health The cell is the basic unit of life. It is a highly organized structure composed of organelles, cytoplasm, and cytoskeletal structures and surrounded by a plasma membrane. Each of these structures has a specific function necessary for the proper development and function of tissues, organs, and organ systems. Dysfunction of cellular components may not only affect the individual cell but may affect the entire organism, resulting in a clinical disorder.

To determine:Whether the life of a cell ends after mitosis and cytoplasmic division.Introduction:Ever organisms present in the environment contains cell. The cell is the basic “fundamental unit” of life. Cell performs a number of important functions. These are termed as cellular activities. Reproduction is also an important cellular activity. All the new cells are formed from the old cell. The process by which a cell produces its progenies is termed as reproduction. Mitosis and cytoplasmic division are types of reproduction.

Unit 3 - Activity 7 - Evaluating Advances in Cellular Biology Assignment
Advances in cellular biology have had a major impact on human health worldwide. As one example, when
the first cases of acquired immune deficiency syndrome (AIDS) appeared in the late 1970s, they frustrated
medical researchers who were trying to find the cause of this wasting disease that could quickly
compromise entire body systems. Researchers suspected the cause to be a retrovirus, a type of virus that
can transform its RNA into DNA, which is subsequently incorporated into the host type of virus that can
transform its RNA into DNA, which is subsequently incorporated into the host cell's genome. If host cells
include the crucial T-lymphocytes that are part of the immune system, then a person infected with the
virus can be left defenseless against infections.<

• FIRST SQUARE: Put each component's function in the first square. The function is what the component does in the cell. Please be very detailed in your answer and use your book to help you.
SECOND SQUARE: In the second square, please put the type of cell that the component is found in.
Although you could talk about prokaryotes vs. Eukaryotes, it would be more important to talk about plant vs. animal cells. Also, if possible, please describe where in the cell this component is found.
THIRD SQUARE: In the third square, please make a sketch of the component. Although we are not all gifted artists, please give this a good attempt. You may want to show where it is in the cell, an inside view of the part, or even a combination of both.
• FOURTH SQUARE: Finally, relate the function of the cellular component to something at FHS. Make sure that the connection is clear and well described.
