How are living organisms and nonliving things similar?

Everything on Earth is made up of matter (chemical elements)
o
What are the four states of matter?

o
How many elements (types of atoms) are on the periodic table of elements?

o
_______________________________________________________________
_______________________________________________________________
What are the four most common elements in living organisms? (Give name and symbol)

_______________________________________________________________
How are living organisms and nonliving things different?
1. Living organisms are made up of at least one cell
o
Although all living organisms are made up of cells, not all living organisms are made up of the same
type of cells
o
Cells come in many sizes, but most are microscopic
o

What is the average size of plant and animal cells? ____________________________

What is the smallest type of cell? ________________________________________

What is the largest cell (can see without a microscope)? ________________________

What is the longest cell (but still microscopic)? ______________________________
Cells come in many different shapes

How many different cell types are in the human body? _________________________

Each cell type has a different shape because each type of cell has a different job
(Form Fits Function!).

In multicellular organisms, all the cells contain the same DNA, but have become
differentiated.

Describe the shape and job of a human nerve cell. Draw a picture of a nerve cell.

Describe the shape and job of a human skin cell. Draw a picture of a skin cell.
Living organisms are made up of at least one cell (continued)
o
Bacteria come in three different shapes, what are they? Draw a picture of each shape.
2. Living organisms contain DNA
o
What does the abbreviation DNA stand for? ______________________________________
o
DNA is sometimes referred to as a “chromosome”.

How many chromosomes (strands of DNA) do humans have? _____________________

How many chromosomes does E. coli (a type of bacteria) have? ___________________

How many chromosomes does lettuce have? _________________________________

Pick two more living organisms. How many chromosomes does that species have?

3. Living organisms need energy to survive (needs a constant food source).
o
Some living organisms can produce their own food. These are known as autotrophs.
o
Give two examples of autotrophs. Give their common and scientific name. Where do they live?

o
Some living organisms need to eat other living organisms for a food source. These are known as
heterotrophs.
 Give an example of an herbivore (common and scientific name, where does it live?)

4. All living organisms grow (by cell enlargement and adding new cells through cell division)
o
What is the largest animal? (common and scientific name, where does it live?)


o
What is the largest plant? (common and scientific name, where does it live?)


5. All living organisms have a metabolism
o
List three reactions in your body that require energy to occur

__________________________________________________________________
__________________________________________________________________
6. All living organisms maintain homeostasis
o
Homeostasis – stable, internal living conditions
o
What is the word origin of “homeostasis”? _______________________________________
7. Respond to stimuli from the environment
o
What type of sensory organs do humans have? ____________________________________
o
How do plants respond to stimuli (direction of sunlight)? ____________________________
_______________________________________________________________________
8. Reproduce
o
Parents pass down DNA to offspring. Sometimes mutations can occur, changing the DNA.
o
What are two ways DNA mutations can occur?


Discovery of the Cell & The Cell Theory

A cell is the smallest unit of matter that can carry on the process of life

What are the three parts of the Cell Theory (proposed in 1800s)?
1. ____________________________________________________________________
2. ____________________________________________________________________
3. ____________________________________________________________________

Who is Robert Hooke (1635 – 1703) and how did he contribute to creation of the cell theory?
o _______________________________________________________________
_______________________________________________________________
