What are cell parts
and
their functions?
In this PowerPoint you will learn
the following:
 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




Surrounds and protects the cell
Makes the cell stiff and strong
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”
chloroplast
 only in plant cells
 contains chlorophyll
 captures energy from sunlight and uses it to
produce food for the cell
 It is like the pizza shop in the mall that makes
food.
 “Food Producers”
cytoplasm
 watery, gel-like material in which cell
parts move
 It is like the hallways of the mall where
people move.
 “Area of Movement”
cell membrane
 holds and protects the cell
 controls what substances come into and
out of the cell
 It is like an entrance you have to pass to
get into the shopping mall.
 “Gate of the Cell”
mitochondria
 produces most of the energy for the cell
 It is like an electrical system of the
shopping mall, which supplies electrical
energy.
 “Powerhouse of the Cell” or “mighty
mitochondria”
vacuoles
 store food, water, and chemicals
 It is like water tank and pipes of the mall,
which store water.
 “Storage Tanks”
nucleus
 regulates and controls cell activities
 acts like the “brain” of the cell
 It is like the mall office, which regulates
and controls activities of the shopping
mall.
 “Control Center”
nuclear membrane
 protects the nucleus
 allow substances to pass in and out of the
nucleus, as the cell membrane
 It is 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”
Golgi bodies
 Moves materials within and into the cell
 “packages” proteins
 “packaging plant” or “bag boy”
Endoplasmic reticulum
(ER)
 2 types—smooth and rough
 Smooth ER makes lipids; rough ER
makes proteins
 “ER” or “highway”
ribosomes
 Makes proteins
 Found on rough ER or floating in
cytoplasm

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
