What are cell parts and
their functions?
In this PowerPoint you will learn
the following:
nine different cell parts
what function each part has
Even if cells are very tiny,
they are made up of
smaller parts, and the parts
do different jobs.
As you can see cells have many parts. This
week you will learn about 9 of these parts.
cell wall
The cell wall is only in plant cells.
Its purpose is to shape and protect the cell like
the outside wall of a shopping mall, which
provides shape and protection for it.
“Supporter and Protector”
cell membrane
 The cell membrane holds and protects the cell. It
controls what substances come into and out of the cell
like an entrance you have to pass to get into the
shopping mall.
 “Gate of the Cell”
cytoplasm
 The cytoplasm is the watery, gel-like material in which
cell parts move and cell activities take place like the
hallways of the mall where people move.
 “Area of Movement”
mitochondria
 The mitochondria produces most of the energy for the
cell, like an electrical system of the shopping mall,
which supplies electrical energy.
 “Powerhouse of the Cell”
chloroplast
 The chloroplast is only in plant cells, like the cell wall. It
contains chlorophyll, which captures energy from
sunlight and uses it to produce food for the cell like the
pizza shop in the mall that makes food.
 “Food Producers”
vacuoles
 The vacuoles store food, water, and chemicals, like
water tank and pipes of the mall, which store water.
 “Storage Tanks”
nucleus
 The nucleus regulates and controls cell activities, acting
like the “brain” of the cell, like the mall office, which
regulates and controls activities of the shopping mall.
 “Control Center”
nuclear membrane
The nuclear membrane protects the nucleus
and also allow substances to pass in and out of
the nucleus, as the cell membrane does the
same for the cell like the main office like the
walls of the mall and its entrance, which protect
the office and let workers in and out.
“Gate of the Nucleus”
chromosomes
 The chromosomes direct the activities of cells like a mall
office director who works in the office and directs all the
activities of the shopping mall.
 “Director of the Cell”
Practice
1. Choose the wrong statement from the
following.
a) Mitochondria produces most of the
energy for the cell.
b) Chloroplasts are “food producers.”
c) Cell wall controls the movements of
materials into and out of the cell.
d) Nucleus regulates and controls all cell
activities, acting as the “brain” of
the cell.
2. Match the cell part to the nick name.
1) Cytoplasm
2) Nuclear membrane
3) Vacuoles
a. Gate of the nucleus
b. Area of movement where cell parts move
c. Storage tanks
3. This cell part is surrounded by a nuclear
membrane.
Is it a nucleus? YES or NO
4. This cell part is the powerhouse of the cell.
Is it a mitochondria? YES or NO
5. Are these chromosomes? YES or NO
