5. Identifiers for Cell Theory

1. All living things are made of cells

A cell is the building block of all life. It is
the smallest structure that can be classified
as a complete living organism.

Definition: Metabolism is the set of

chemical reactions that occur inside of

cells.

Glucose

metabolism

2. All cells metabolize nutrients

3. All cells can reproduce themselves

4. All cells contain genetic material

in the form of DNA.

DNA stands for

deoxyribonucleic acid

5. All living things maintain a steady

balance of water, nutrients and energy

known as homeostasis.

Multiple Select

What structures do all cells have in common?

• cytoplasm

• Ribosomes

• DNA

• cell membrane

• nucleus

Match

Match the following pictures to the types of cells:

animal

plant

bacteria

• animal

• plant

• bacteria

All cells, and therefore all living things, have
some organelles and structures in common.

Cell Structures

Prokaryote

Eukaryotes

All cells are surrounded by a cell

membrane. Membranes are selectively

permeable which means they only let certain

things enter and exit the cell.

Cell Structures

All cells are full of an aqueous solution call the
cytoplasm. It is an aqueous solution
because the solvent is water! The cytoplasm
contains all of the nutrients and organelles the

cell needs.

Cell Structures

Every cell contains genetic material in the
form of DNA. This DNA is wrapped around
proteins and packaged into large, complex

structures calledchromosomes.

Cell Structures

Prokaryote

Eukaryote

The information that is stored in DNA is used to make

all of the cell’s proteins. Ribosomes of the cell
that read these instructions and make all of

the cell’s proteins.

Cell Structures

Nucleus controls the cell’s
function because it holds

DNA

Cell Structures

Organelles like the ones shown below that have

their own membranes are known as
membrane-bound organelles.

Cell Structures

Golgi
body

Mitochondrion
Endoplasmic

Reticulum

Lysosome

Multiple Choice

To control what enters or leaves the cell is a function of _________.

• Cell Wall

• Cell Membrane

• Nucleus

• Mitochondria

Multiple Choice

I make proteins for the cell. What am I?

• ribosome

• mitochondria

• chloroplast

• lysosome

The Endosymbiotic (Living Inside) Theory

A prokaryotic cell (the first cell) engulfed two other cells, forming eukaryotic cells known as mitochondria and chloroplast organelles.
