• movement of muscles attached to the base of the hair

• sensory nerves present at the base of the hair taking information to the brain

• body fat accumulated near the hair follicle

Multiple Choice

An atom of the element strontium has 38 protons, 38 electrons, and 50 neutrons. What is the atomic mass of strontium?

• 76; the atomic mass is the number of protons and electrons

• 88; the atomic mass is the number of protons and neutrons

• 38; the atomic mass is the number of protons

Multiple Choice

Which question could be answered using this data?

• What is the relationship between the amount of CO2 in the atmosphere & the global temp?

• What is the best way to reduce the amount of CO2 in the atmosphere?

Multiple Choice

Which conclusion is best supported by the data shown in the graph?

• Increased concentrations of CO2 in the atmosphere are associated with increased global temp.

• Increased global temps are not caused by changing CO2 levels.

• Both global temp and CO2 in the atmosphere will continue to increase in the future.

I can explain what a
cell is, how they
were discovered, and
the 3 steps of Cell
Theory.

Cells are the primary building blocks of life.
They come in all shapes and sizes.

What is a Cell?

Some cells are so small and can only be
observed under a microscope. But some
are large enough to be held, like eggs!

Multiple Choice

Cells are the primary _________ blocks of life. They come in all shapes and sizes.

• functional
• metabolic
• building

• behavioral

Hooke's discovery led to the development of

The Cell Theory

German scientists Theodor Schwann, Matthias
Schleiden, and Rudolph Virchow consecutively
developed the classical cell theory.

It is a principle in Biology that is fundamental
to our understanding of all living organisms,
summarized into three tenets.

1

A living organism can be made of just one cell

(like an amoeba) or trillions (like the human body!)

All organisms are made up of cells.

2

That's why cells are often referred to as the basic

unit of life. To be considered a life form, something

needs to have at least one cell.

​Cells are the basic unit of life.

Multiple Choice

All organisms are made up of ________.

• Molecules
• Planets
• Cells
• Atoms

3

A cell cannot exist spontaneously nor come

out of a nonliving thing.

All cells come from other cells
that are already existing.

Multiple Choice

Cells are the basic unit of _________.

• matter
• energy
• life
• space

Multiple Choice

All cells come from other _______ that are already ____________.

• atoms, pre-existing
• organisms, newly formed
• cells, existing

• molecules, spontaneously generated

Summing Up Cells

Cells are the building blocks of life, and
they come in various shapes and sizes.

The development of the microscope led
to the discovery of cells.

The three tenets of cell theory state that
all organisms have cells, cells make life
functions happen, and cells can only
come from other living cells.

Multiple Choice

Prokaryote: "Pro" rhymes with "No," so they ______ have a nucleus.

• Do

• Don't

● Single-celled organisms (unicellular)
● simple
● smaller
● nucleoid
● no nucleus
● no membrane bound organelles

Multiple Choice

All of the following are true about a prokaryote except ......

• No nucleus

• Simple

• Multicellular

Why can Prokaryotes reproduce so quickly?

Prokaryotes are simple and smaller in size. They are also unicellular and
do not have membrane bound organelles, therefore they do not have a
nucleus. Instead, they have their DNA as a free floating single circular
chromosome called a “nucleoid.” The nucleoid is located in the
cytoplasm and as a result, it is easy to replicate the DNA and the cell
through binary fission (talk more about later). This allows the cells to
quickly reproduce and the mutate/evolve. It is for this reason there are
billions of different prokaryotes.

Advantages and disadvantages of being
a Prokaryote.

Advantages:

1. simple

2. small

3. reproduce quickly

4. so many of these cells

5. can adapt easily to

environment

6. recycle resources in our

environment

Disadvantages:

1. cannot metabolize quickly so
they stay small
2. may not survive environment
because they mutate so much

Multiple Choice

Which is NOT an advantage of a prokaryote?

• Ability to perform photosynthesis
• Ability to form unicellular structures

• Ability to reproduce faster than eukaryotes.

● DNA in nucleus
● nucleus
● membrane bound organelles
● larger
● complex
● multicellular (many)

Advantage and disadvantages of
being a Eukaryote.

Advantages:
1. larger
2. more complex
3. can be multi or unicellular
4. membrane bound
organelles
(specific roles)
5. DNA - protection and allows
better control in cell
6. waste disposal and
metabolism are better

Disadvantages:

1. not easy to reproduce quickly

(depends on if you are
multicellular or unicellular)

2. cell is more complex

Multiple Choice

"Eu" rhymes with "Do," so a eukaryote _______ have a nucleus.

• don't

• could
• might
• do
