What are cell parts andtheir 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
