6. Living things
Living things are organized
Four macromolecules in cells are:
Some living things are unicellular which means:
Examples:
Some living things are multicellular which means:
Multicellular organisms have different levels of organization.
Groups of cells that work together to perform a specific function are:
Tissues that work together and carry out a specific function are called:
Organs that work together and perform a specific function are called:
Organ systems work together and perform all the functions______________________________
Living things grow, develop, and reproduce:
When a unicellular organism grows_________________________________________________
When a multicellular organism grows_______________________________________________
Living things use energy:
Some living things covert light energy to chemical energy. These are called autotrophs. We can also
call them ____________________________. (This isn’t in the book. You know this from the last
chapter!)
Chemoautotrophs _____________________________________________
Animals and fungi are examples of ________________________________.

Living things respond to stimuli:
A change in an organism’s environment is called ____________________________.
Example of an organism responding to a stimulus:
What do living things need?
List the three things all living things need:
A specific environment where an organism lives is called:________________________________
Living things need food and water. Food is used for _______________________. Water is in all
__________ and helps them ___________________________.
Day 2: How are living things classified?
Scientists use a classification system to group organisms with ___________________________.
Classifying living things makes it easier to organize organisms and recall how they are
__________________________________________________________________________.
Scientists use the naming system called____________________________________________.
This system was created 300 years ago by a man named, _______________________________.
All scientific names are in ______________________. ____________________ is the
scientific name for humans.
The branch of science that classifies living things is called _____________________________.
All living things on Earth into three groups called _________________. Domains are divided into
____________, and then ________________________, ______________________,
_____________________, __________________________, _________________________,
and _____________________________.

Day 3: Chapter 5 Lesson 2: What are cells?
All living things have _____________________, the basic unit of an organism. Most organisms
have only ___________________.
Most cells are so small they cannot be seen without a ___________________________.
What are cell made of?
Cells are surrounded by an outer structure called a _______________________________.
The cell membrane keeps substances inside the cell. About 70% of the inside of a cell is
___________.
Types of Cells:
There are two main types of cells. These are _________________________________ and
_______________________________.
Prokaryotic cells do not have a _____________ or other membrane bound organelles.
Organelles are structures in cells that __________________________________________.
Most prokaryotes are ________________________________ such as ________________.
Eukaryotic cells have a _____________________ and other membrane bound organelles.
Most multicellular organisms and some unicellular organisms are _______________________.
What structures are in both prokaryotic cells and eukaryotic cells?
The Outside of a Cell:
The _______________________surrounds a cell. This is similar to a ____________ around a
school. The cell membrane helps keep the ____________________ inside a cell separate from
the ________________________ outside a cell.
Cell Membrane: The cell membrane is made up of ______________ and ______________. Cell
membranes can be found in plant and animal cells.
Cell Wall: Some cells have a cell wall. The cell wall is a ______________, _________________
layer outside the cell membrane. Cells in plants, fungi, and many types of bacteria have cell

walls. Cell walls provide ___________________ and help protect the cell from the
_________________________________.
Day 4: The Inside of a Cell:
Water gives cells their ________________ and helps keep the structures inside a cell
______________. The organelles inside a cell perform __________________________.
They control:
Cytoplasm:
The liquid part of a cell inside the cell membrane is called the ______________________.
Controlling cell activities:
The information that controls all of a cell’s activities is store in the _______________________.
In prokaryotic cells, DNA is stored in the _________________________________________.
In eukaryotic cells, DNA is stored in an organelle called the ________________________. The
nucleus is often called the “brain of the cell.”
Energy for the cell:
Eukaryotes have special organelles, the ______________ and _____________________ that
process energy.
Mitochondria:
____________________________ are organelles that break down food and release energy.
This energy is stored in molecules called _____________________. ATP provides a cell with
energy to perform many functions, such as:
Chloroplasts:
Plants and many other autotrophs have ______________________ and ___________________.
______________________ capture light and convert it into __________________________ in
a process called ____________________________.
Protein Production:
Cells use ___________ for many functions. These proteins are made on the surfaces of
_______________ that are in the cytoplasm. Some ribosome are attached to the
___________________________. It is made of folded _________________. Proteins can be
processed and move inside the cell through the endoplasmic reticulum.
Cell Storage:
The ____________________ packages proteins in tiny organelles called _______________.
Vesicles transport proteins around a cell. A ______________________ is the largest organelle in
