Cells Information Gap Activity - Sheet A
Name: ___________ Homebase: _____________
There are two main types of cells – animal and ____________________ cells. Each cell is made up of parts called
_______________________. Each organelle has a different ___________________ and carries out a different
________________ for the cell.
Animal Cells
Cells from ___________________ have several organelles in
common. They include the cell membrane,
__________________, mitochondrion, __________________,
cytoplasm, __________________________ and many more.
The cell membrane is a thin, flexible ___________________
____________________that encases the cell and
____________________ what goes in or comes out.
Cell membranes are ______________________________ under light microscopes, which is why it can be hard to
___________________ individual animal cells under light microscopes.
The cytoplasm is a ______________________________ liquid that fills most of the cell and contains hundreds of
different chemicals. New substances are ____________ and ___________________ is released and stored there.
Think of the ____________________________________ as the chemical factory of the cell.
Vacuoles are ______________________________areas that may contain air, ________________, wastes and
__________________________________. ______________________________ cells often contain several small
vacuoles. They are not normally visible under light microscopes.
The ________________________________________ is the “control room” of the cell. It contains ____________,
which is like a _________________________________________________________ that tells the cell how to
develop and _______________________________. Nuclei are often visible under light microscopes.
The mitochondria is a small organelle that can’t be seen using a light microscope.
Its job is to ________________________________________ to release the ________________________ that the
cell needs to __________________________.
_________________________ break down, recycle and/or destroy _____________, old organelles, viruses and
_________________________ into other chemicals which the cell can then _________ or dispose of.
Plant Cells
Like animal cells, plant cells also contain a
________________________, lysosomes, cytoplasm,
_______________________, a cell membrane, but instead
of many ________________________, plant cells contain
_______________________________ filled with cell sap.
Unlike _____________________ cells, plant cells contain
___________________________ and a cell wall.
Unlike animals, plants need to make their own _________ in a process
known as photosynthesis. This occurs in ________________________
called chloroplasts inside leaf cells. Chloroplasts may be seen using a
light microscope.
_______________________ in the cell use light energy from the
_______ to convert ___________________________________ and
water into chemical energy in the form of _______________________
(a type of sugar). This is then used as food for the plant.
________________________is made as a waste material.
Unlike animal cells, plant cells have a ______________________which contains a tough, fibrous material called
cellulose and provides the support needed by the ______________________ and the entire plant. Cell walls are
easy to ___________ under microscopes, which makes it easy to identify individual plant cells under microscopes.
There are other organelles, which you might want to know about, but we’ve kept it simple for Grade 6!
Single-Celled (Unicellular) Organisms
These organisms are called _______________________,
meaning “one cell”. This cell carries out all the required
________________________________ such as food
intake and ______________________.
Since some unicellular organisms show both __________
and animal characteristics, they are often classified not
as plants or animals, but as _____________________.
Multicellular Organisms
Organisms with ____________ than one cell are
known as multicellular organisms. The larger the
organism, the more specialized cells it has. A
________________________ cell carries out a very
specific _____________________ for the organism.
____________________ contain more than 200
types of specialized cells. _____________________
cells carry food and oxygen around the body;
muscle cells assist movement; while nerve cells
send messages from the ____________________
to the muscles.
What do you think the other specialized cells do?
Bone cells?_______________________________
________________________________________
Fat cells? _______________________________
________________________________________
Groups of Cells, Tissues and Organs
The different specialized cells in our bodies are organized into
_________________ to help them work more effectively.
Groups of similar________________________cells are called tissue.
________________ in turn may be grouped ___________________
to form an _____________. Just as ______________________ do a
specific job for the cell, organs do a specific job for an organism.
For example, _____________ cells form heart tissue, which makes
up the heart, the _____________ specialized for pumping blood
around the human body. Some other human organs made from
specialized ___________________________________ are the skin,
_______________, intestines, liver, kidneys and _______________.
