Unit 1 Biology – Introduction to Cells
Minds On . . . What are cells? What do they do? Where are they found? What are they made up of?
Brainstorm the answer to some of these questions:
What do cells look like? Use the microviewers to observe some basic cell structure including cells of your body!
Set 58 Microviewer slide – CELL STRUCTURE (read through the slide pamphlet as you observe the slide and fill in
the blanks below):
In the early part of the 19th century, scientists concluded that _____________________________________________.
These slides have been selected for you to notice that cells of different plants and animals have variations in their
structure adapted to their __________________________. A knowledge of basic ____________________ of the cell
is necessary for _____________________ all ______________ _______________. A magnification of 300x means
___________________ and that the picture that you are looking at is _________________________ than the object.
1) Cork – Mag: ______x. What are the “dark-walled” boxes called that you are looking at? __________________.
Are they “real” cells? Explain.
2) Onion Skin – Mag: ______x. What was this layer stained with and why?
What is inside the cell wall? What does it look like?
What isC and D pointing at?
What structure can you see that is unique to plant cells?
3) Green Leaf – Mag: ______x. What are some structures that you can see in A?
What is B, C, D, and E pointing at?
4) Cheek cells – Mag: ______x. Can you identify the 3 parts that make up almost all cells? What are they?
What are the oval granules seen near the head of the arrow?
5) Blood Cells – Mag: ______x. What is neat about the structure of A?
How is the cell at B identified? What is unique about it?
What is different about the cell at C?
What is D pointing at and what does it look like?
6) Nerve Cells – Mag: ______x. Where was this slide made from?
Describe the structure of a nerve cell. Why can an entire brain cell not be seen here?
7) Bacteria – Mag: ______x. Where are these bacteria from?
How is their structure and cell parts different from other cells?
8) Virus – Mag: ______x. Describe what is seen in this slide.
What was used to take this photo?
Do you think viruses are cells? Why or why not?
Set 10 Microviewer slide – CELLS OF YOUR BODY (read through the slide pamphlet as you observe the slide and
fill in the blanks below):
We have all heard the common phrase, “____________________________________________________________.”
The human body is NOT like a __________ which can be made of a single kind of ____________ ____________.
What are some different kinds of cells in the body? _________________________________________________. A
magnification of 900x means ___________________ and that the picture that you are looking at is
_________________________ than the object.
1) Cheek Cells– Mag: ______x. Describe what you can see including the dark spot.
2) Blood Cells – Mag: ______x. What are some interesting facts about red blood cells?
White blood cells?
3) Lymph Gland cells – Mag: ______x. Where are lymph glands located?
What other cell type are lymph gland cells similar to and why? Describe how they’re similar.
4) Bone cells – Mag: ______x. Is bone alive? _______________________________________________________
Describe the structure of bone including what it is made up of.
5) Voluntary muscle cells – Mag: ______x. Describe these cells including the structures you can see.
6) Involuntary muscle cells – Mag: ______x. This slide was made from a piece of ______________________.
How are these cells different from Voluntary Muscle Cells?
Where are Involuntary muscle cells located?
Where are Voluntary muscle cells located?
7) Nerve Cells – Mag: ______x. What is A and B pointing to?
8) Gland Cells – Mag: ______x. Where are these cells from? ____________________ What can you see at A and B?
2.1 Plant and Animal Cells (Pages 29 – 32)
Biology is a science is built on three simple but very important ideas. These three ideas form the cell theory. The cell
theory states that



All living things are made up of cells, but these cells may be very ______________ or very
____________. The simplest organisms are ____________ and ____________. These simple, singlecelled life forms are called _______________. The cells do not have a ______________. More complex
cells can exist as single-celled organisms or multicellular organisms. The cells of these organisms, knows
as _______________, have a more complex internal organization, including a nucleus. Eukaryotes include
all ___________, __________, __________, and _________, from the tiniest Amoeba to the longest whale
and the tallest tree. The cells of eukaryotes are much ____________ than the cells of prokaryotes: tens to
thousands of times ________.
Cell Structure
Your body is made up of many specialized organs that carry out all the processes needed to live. In
the same way, a _______________ cell also has specialized parts, called ______________, carry out
specific functions necessary for life.
Label the parts of the Plant and Animal Cells
Based on how a cell functions, create an analogy to compare the structure (cell parts) and function of a cell
to something else you know (like a factory or school, etc).
