THE HISTORY OF CELL BIOLOGY
Both Living and Nonliving Things are composed of molecules made from
chemical elements such as carbon, hydrogen, oxygen, and nitrogen. The
organization of these molecules into Cells is one feature that distinguishes Living
Things from all other matter. The CELL is the smallest unit of matter that CAN
Carry on ALL the PROCESSES OF LIFE.
OBJECTIVES:
1. Name the scientists who first observed living and nonliving cells.
2. Summarize the research that led to the development of the cell theory
3. State the three principles of the cell theory.
4. Explain why the cell is considered to be the basic unit of life.
THE DISCOVERY OF CELLS

All living things are made up of one or more cells.

The ______________ is the smallest unit that can carry on all of the
processes of life.

Cells were not discovered until after the invention of the ________________
in the early seventeenth century.

One of the First Microscopes was made by the Dutch drapery store owner
______________________ ______ _________________

In 1665, the English Scientist ____________________used a microscope to
examine a thin slice of cork and described it as consisting of "a great
many little boxes".

It reminded him of the small rooms in which monks lived, so he called the
"________________".

In 1838, German Botanist ________________ ________________ studied a
variety of PLANTS and concluded that all PLANTS "ARE COMPOSED OF
CELLS".

The next year, German Zoologist ________________ ________________
reported that ANIMALS are also made of CELLS.

In 1855, German Physician _____________ _______________ induced that
"THAT CELLS ONLY COME FROM OTHER CELLS".
The COMBINE Work of these early scientists make up what is now known as the
modern ___________________________________.
The Cell Theory consist of THREE Principles:
A.
B.
C.
PART II INTRODUCTION TO CELLS
OBJECTIVES:
1. Explain the relationship between cell shape and function.
2. Identify the factor that limits cell size.
3. Describe the three basic parts of a cell.
4. Compare prokaryotic cells and eukaryotic cells.
5. Analyze the relationship among cells, tissues, organs, organ systems, and
organism.
CELL DIVERSITY

Not all cells are alike.

There are least __________types of cells in the human body, ranging from
flat cells to round cells to rectangular cells.

Cells come in a variety of ___________, ____________, and
________________.

THE __________ OF A CELL DEPENDS ON IT'S ______________.
There are Two MAIN TYPES OF CELLS:
1. ______________________ are small bacterial-type cells
They lack a ___________ - ______________________ nucleus and organelles
2. ______________________ are larger plant and animal cells that have a distinct
nucleus with a ______________ and “tiny organ-like structures” ________________
BASIC PARTS OF A CELL
Cells contain a variety of Internal Structures called ________________________.
Organelles PERFORM SPECIFIC _______________________ FOR THE CELL.
Just as the organs of a multicellular organism carry out the organism's life
functions, the Organelles of a cell Maintain the Life of the Cell.
There are many different cells, however all cells have
an __________________, ___________________, and a ___________ _________.
ORGANELLES OF THE EUKARYOTIC CELL

________________________________________ - (THE OUTER
BOUNDARY)
This is the cell's outer boundary that covers a cell's surface and acts as a
barrier between the inside and the outside of a cell.

Inside the Cell are a Variety of Organelles, most of which are surrounded
by their own Membrane.
____________________________ (THE INTERIOR SUBSTANCE)

EVERYTHING BETWEEN THE PLASMA MEMBRANE AND THE
NUCLEUS
The _____________________ PLUS THE __________________ makes up the
CYTOPLASM.
CONTROL CENTER - (DNA)

A Large Organelle near the Center of the Cell is the
_____________________. IT CONTAINS THE CELL'S GENETIC
INFORMATION AND CONTROLS THE ACTIVITIES OF THE CELL.

The PRESENCE OR ABSENCE of a NUCLEUS is important for
Classifying Cells.

ORGANISMS WHOSE CELL CONTAIN A NUCLEUS AND OTHER
MEMBRANE-BOUND ORGANELLES ARE CALLED
_______________________.

ORGANISMS WHOSE CELLS NEVER CONTAIN (OR LACK) A
NUCLEUS AND OTHER MEMBRANE-BOUND ORGANELLES ARE
CALLED _________________________.
The difference between Prokaryotes and Eukaryotes is such an important
distinction that Prokaryotes are placed in Two Domains Separate from
Eukaryotes - Domains Bacteria and Archaea.
